Connect2id server release notes

15.4 (2024-03-11)

Summary

Adds a new Security Token Service (STS) web API to issue signed JWTs for JWT-secured Authorisation Requests (JAR, see RFC 9101) and private_key_jwt authentication. Intended when an Identity Provider based on the Connect2id server acts an OAuth 2.0 client / OpenID relying party in federated login scenarios. The signature of an issued JWT can be validated using the server JWK set published at the /jwks.json endpoint.

Configuration

/WEB-INF/oidcProvider.properties
- op.sts.apiAccessTokenSHA256.* -- New optional configuration property. Specifies a master access token for the STS web API, represented by its SHA-256 hash (in hexadecimal format). The hashed storage is intended to prevent accidental leakage of the token through configuration files, logs, etc. The token is of type Bearer, non-expiring and must contain at least 32 random alphanumeric characters to make brute force guessing impractical. If not specified the web API is disabled.
  
  Additional access tokens, to facilitate token roll-over or for other needs, can be configured by appending a dot (.) with a unique label to the property name, e.g. as op.reg.apiAccessTokenSHA256.1=abc....
/WEB-INF/log4j.xml
- Updates the PatternLayouts of the RollingFile and Console appenders to comply with a recent Log4j library change.

Web API

/sts/rest/v1/
- New Security Token Service (STS) web API. Enabled if it has a master API access token (op.sts.apiAccessTokenSHA256) configured.
/sts/rest/v1/issuer
- New resource to issue signed JWTs for JWT-secured Authorisation Requests (JAR) and private_key_jwt authentication. Supports the RSxxx, PSxxx and ESxxx JWS algorithm families. The JWTs are generated according to a built-in template that defines the acceptable JWT header parameters and claims set. The template ensures the JWT is compliant with the respective specification and potential errors, such as including a sub claim in signed request object (JAR), are prevented.
  
  Supported templates:
  - JAR -- For issue of signed JWT-secured Authorisation Requests (JAR), also called request objects in OpenID Connect.
  - private_key_jwt -- For issue of private key client authentication JWTs for use at the token and other endpoints of an OAuth 2.0 authorisation server / OpenID provider.

Resolved issues

Corrects the OP5109 log INFO message that records whether a master API token for the client registration endpoint is configured (issue server/978).
Fixes the shipped /WEB-INF/log4j.xml configuration to comply with a recent Log4j library change. In Connect2id server 15.3 this caused the log lines to contain only the log message (%m), with timestamp, etc. missing (issue server/980).
Logs token success response (OP6225) and error response (OP6226) at INFO level, with client ID, grant type and other details (issue server/982).

Dependency changes

Updates to org.slf4j:slf4j-api:2.0.9
Updates to com.github.dubasdey:log4j2-jsonevent-layout:0.0.8

15.3 (2024-03-05)

Web API

/session-store/rest/v2/
- The sessions resource receives a new optional skip_last_used_update query parameter for GET requests for individual subject sessions. When true the internal timestamp that records the last session use will not be updated, leaving the session maximum idle time expiration unaffected. When false the last used timestamp of the session will be updated. The default value is false. Only Connect2id server deployments that persist the subject sessions to a database or Redis can skip the update of the session last used timestamp. In deployments using Infinispan in-memory replication clustering the query parameter will be disregarded and have no effect.

Resolved issues

Updates the SQL store connector to log the SQL transaction isolation level at INFO level at Connect2id server startup. The log message receives the IS0143 identifier (issue sql-store/38).
Removes a redundant ConcurrentMap.remove call in the subject session store when updating the last used timestamp of a retrieved persisted subject session with a positive max_idle value (issue session-store/97).
Improves the performance of the authorisation session web API, the authorisation code grant processing, the refresh token grant processing and the token introspection processing by skipping the last used timestamp update of retrieved subject sessions where appropriate (issue server/975).
Adds a org.apache.logging.log4j:log4j-slf4j-impl dependency to enable jOOQ query logging at DEBUG level (issue server/976).

15.2 (2024-02-16)

Configuration

/WEB-INF/httpClaimsSource.properties
- op.httpClaimsSource.includeSubjectSessionID -- New optional configuration property of type boolean. Enables / disables inclusion in the request of the subject (end-user) session ID where the claims sourcing was authorised. Disabled by default.
- op.httpClaimsSource.includeSubjectSession -- New optional configuration property of type boolean. Enables / disables inclusion in the request of the subject (end-user) session where the claims sourcing was authorised. Disabled by default.

SPI

Upgrades the Connect2id server SDK to com.nimbusds:c2id-server-sdk:5.2
- New ClaimsSourceRequestContext.getSubjectSessionID method that returns the ID of the associated subject (end-user) session where the claims sourcing was authorised.
- New SubjectSessionID interface to represent subject (end-user) session identifiers.

Resolved issues

When the op.issuerAliasMode configuration property is set to PERSISTED_GRANT_ISOLATION back-channel logout notifications on subject session close and expiration events must be disabled (issue server/969).

Upgrades to com.nimbusds:oidc-claims-source-http:3.0
Updates to Log4j 2.22.1

15.1.1 (2024-01-29)

Resolved issues

Fixes generation of the optional "sid" (session ID) claim in ID tokens which relied on a non-thread safe use of a SHA-256 message digest. In Connect2id server deployments when two or more "sid" claims need to be generated within a short length of time (<< 1 second) this could result in the "sid" claim receiving an incorrectly computed value or cause the value to leak into the "sid" claim of another ID token. Connect2id server deployments with clients / OpenID relying parties registered to receive logout notifications with a "sid" parameter are strongly advised to update (issue server/967).

Dependency changes

Updates to com.nimbusds:infinispan-cachestore-dynamodb:6.0.1
Updates to com.nimbusds:c2id-server-property-source:2.0.1
Updates to com.nimbusds:software-statement-verifier:2.2.7

15.1 (2024-01-08)

Configuration

/WEB-INF/oidcProvider.properties
- op.reg.rejectNonTLSRedirectionURIs -- The configuration property is extended to apply to native applications (OAuth 2.0 clients registered with applicattion_type set to native). Previously it applied only to web applications (clients registered with application_type set to web). The default value remains true (non-TLS web host URLs rejected).

Resolved issues

Configured custom scope value to claim name mappings (op.claims.map.*) must be observed when processing prompt=none and equivalent OpenID authentication requests (issue server/961).
Processing of OAuth 2.0 authorisation and OpenID authentication requests is hardened to ignore query parameters with illegal escape sequences in the query parameter name or value. Previously such illegal escape sequences in the query string would produce an unchecked exception resulting in an HTTP 500 Server Error in the authorisation session start (POST) request (issue server/958).
Logs an OP1202 INFO message whenever the SSO for an end-user is disabled due to the requesting client matching the optional op.sso.disableForSelectedClients configuration (issue server/959).

Dependency changes

Updates to com.nimbusds:oauth2-oidc-sdk:11.9.1

15.0 (2024-01-02)

Summary

Upgrades to Java 17.
Upgrades to Jakarta Servlet 6.0 and Jakarta JAX-RS 3.1. The minimum supported Apache Tomcat version becomes 10.1.x.
The Connect2id server SDK (v5.0) is upgraded to Java 17 and Jakarta Servlet 6.0. Plugins that retrieve a ServletContext from the InitContext interface will receive a jakarta.servlet.ServletContext instead of a javax.servlet.ServletContext.
Refresh tokens issued by the Connect2id server can be optionally set to expire after a period of idle time, expressed in seconds. This enables an identity provider to establish a session for a given end-user and client application, with the refresh token remaining active as long as the client keeps using it frequently enough to obtain new tokens. When use of the refresh token stops, due to the end-user leaving the client application, and the maximum idle time is reached, the refresh token becomes invalidated. The client application must make a new authorisation request, to log in the end-user and / or obtain their consent, in order to receive a new refresh token.

The refresh token maximum idle time is settable per end-user and / or client, can be applied to both regular and rotated refresh tokens, and is disabled by default. The refresh token maximum idle time is independent of the optional refresh token lifetime setting, and should not exceed it.
For token responses containing an access and refresh token, the lifetime of the access token will be automatically trimmed so that it doesn't exceed the maximum idle time or lifetime of the refresh token, whichever is shorter.

Configuration

/WEB-INF/oidcProvider.properties
- op.idToken.ignoreClaimsSourceErrors -- New optional configuration property, deprecating the existing op.idToken.ignoreUserInfoError which will be removed in a future major Connect2id server release.
/WEB-INF/infinispan-*-{mysql|oracle|postgres95|sqlserver}.xml
- Sets the HikariCP property "poolName" to sqlStore so that all SQL connection pool related metrics appear under the sqlStore.* prefix instead of the name of the first declared Infinispan map / cache (sessionStore.subjectMap in the regular Connect2id server edition, or tenantRegistry.tenants in the multi-tenant Connect2id server edition).
- Upgrades the SQL schema by adding a new rtm (refresh token maximum idle time) column to the long_lived_authorizations table. In existing deployments the Connect2id server will automatically add the new column on startup, unless dataSource.createTableIfMissing is disabled.

Web API

/authz-sessions/rest/v3/
- The consent object receives a new optional refresh_token.max_idle parameter. May be used to specify a maximum idle time, in seconds, for the issued refresh token. If the refresh token is not used within this time period the Connect2id server will invalidate it due to inactivity. The default value is 0 (no idle time expiration).
/direct-authz/rest/v2
- The request object receives a new optional refresh_token.max_idle parameter. May be used to specify a maximum idle time, in seconds, for the issued refresh token. If the refresh token is not used within this time period the Connect2id server will invalidate it due to inactivity. The default value is 0 (no idle time expiration).
/token
- The token response will include a refresh_token_expires_in parameter for responses that contain a refresh token that is set to expire. When present the value is a positive integer indicating the number of seconds until the refresh token expiration, similar to the standard access token expires_in parameter. Responses with refresh tokens that don't have a maximum lifetime set will not include this parameter. Clients can use this parameter as a hint when to make a new request to the Connect2id server authorisation endpoint. The invalid_grant error code remains the standard and recommended method for clients to detect when the refresh token has become invalid, due to expiration or revocation.
- For token responses with an expiring refresh token, the lifetime of the issued access token is guaranteed to never exceed the lifetime or the maximum idle time of the refresh token. If the lifetime of the access token would exceed the refresh token lifetime or maximum idle time, it will be automatically trimmed to achieve expiration parity with the refresh token.
/authz-store/rest/v3/authorizations
- The OAuth 2.0 / OpenID Connect authorisation object receives a new optional rtm member, representing the refresh token maximum idle time, in seconds. The default value is 0 (no idle time expiration).
/monitor/v1/metrics
- All SQL store Hikari connection pool metrics are now published under the sqlStore.pool.* prefix. The [infinispan-cache-name].sqlStore.pool.* prefix is no longer used.

SPI

Upgrades the Connect2id server SDK to com.nimbusds:c2id-server-sdk:5.1
- Upgrades to Java 17.
- The InitContext.getServletContext() method returns jakarta.servlet.ServletContext instead of javax.servlet.ServletContext (breaking change).
- The ServletInitContext constructor accepts jakarta.servlet.ServletContext instead of javax.servlet.ServletContext (breaking change).
- The RefreshTokenSpec adds support for setting a maximum idle time for the refresh token.

Resolved issues

Fixes the HTML representation of the static pages for HTTP 404, 405, 500 and all other errors that aren't handled by the web application (issue server/953).
Removes support for legacy cnf.x5t encoding in access tokens issued by Connect2id server 7.x and older releases (issue authz-store/229).
The access token lifetime must be automatically trimmed to match the lifetime or the remaining lifetime of the refresh token (for expiring refresh tokens)(issue authz-store/228).
The rtl (refresh token lifetime) value of authorisation objects returned by the authorisation store web API must reflect the remaining lifetime in respect to rti (refresh token issue time) when the refresh token was configured for rotation (issue authz-store/224).
The rti (refresh token issue time) value for long-lived authorisation objects with configured rotation must be updated after a refresh (issue authz-store/224).
The expiration time of self-contained (JWT-encoded) refresh tokens must not be advanced when the refresh token is set for rotation and a new refresh token is returned at the token endpoint in response to a refresh token grant (issue authz-store/225).
Removes the /client-reg/* endpoint alias to /clients/* that was deprecated in Connect2id server 3.0 (2015-03-26) (issue server/911).
Removes the authorisation store and session banner pages (issue server/763).
The SQL store ExpiredEntryPagedReaper must log the IS0128 debug message in all execution paths (issue sql-store/37).
Fixes the Infinispan metadata recreation for authorisation code entries persisted to an SQL database. The bug was introduced in Connect2id server 9.1.1 in response to issue authz-store/176 and caused expired entries to remain persisted in the "pending_codes" table (issue authz-store/230).

14.11.1 (2024-01-29)

Resolved issues

Fixes generation of the optional "sid" (session ID) claim in ID tokens which relied on a non-thread safe use of a SHA-256 message digest. In Connect2id server deployments when two or more "sid" claims need to be generated within a short length of time (<< 1 second) this could result in the "sid" claim receiving an incorrectly computed value or cause the value to leak into the "sid" claim of another ID token. Connect2id server deployments with clients / OpenID relying parties registered to receive logout notifications with a "sid" parameter are strongly advised to update (issue server/967).

14.11 (2023-12-08)

Web API

/logout-sessions/rest/v1/
- Logout requests initiated by an OpenID Relying Party (RP) with a post_logout_redirect_uri parameter will be allowed to proceed if the RP includes its client_id parameter. Previously such redirections were allowed to proceed only when a valid id_token_hint was provided in the request. With this change RPs that wish to perform a post-logout redirection have the choice to include an ID token hint, their client ID, or both, in order to enable the Connect2id server to validate the URI by checking it against the registered post_logout_redirect_uris metadata parameter for the RP.

Resolved issues

The client registration endpoint must allow registration of native applications with a localhost or loopback IP frontchannel_logout_uri (issue server/950).
The SQL database connector must not serialise the jOOQ Query to an intermediate String unless when dealing with Oracle (N)CLOB chunking. By using direct Query execution a PreparedStatement can be correctly inferred (issue sql-store/35).
Updates SQLStore.write() to switch from the deprecated jOOQ mergeInto() to an insertInto() for PostgreSQL and Oracle databases (issue sql-store/34).

14.10 (2023-11-22)

Summary

Connect2id server deployments with an SQL database receive an optimised purge task and SQL query for expired records, such as records for expired subject sessions or identifier-based access tokens. The page limit in the SQL query to select expired records is made configurable, to enable further performance tuning.

A Java system property to override the maximum lifetime of SQL connections in the connection pool is also made available.

Configuration

/WEB-INF/infinispan-*-{mysql|oracle|postgres95|sqlserver}.xml
- Upgrades the SQL store schema to v3.2.
- dataSource.maxLifetime -- New optional Java system property to override the default maximum lifetime of SQL connections in the Hikari connection pool. The value is expressed in microseconds and must not be shorter than 30000 (30 seconds). The default value is 1800000 (30 minutes).
  
  This configuration can be used to address Hikari warnings (recorded in the Connect2id server log) "Failed to validate connection (Closed Connection)".
- dataSource.expiredQueryPageLimit -- New optional Java system property to override the default page limit of SQL queries to select expired records, such as the records of expired subject sessions. The page limit value is 1000 records.
  
  This configuration can be used to optimise the retrieval of expired records by the Infinispan entry purge task.
- Upgrades the SQL database connector and the sessionStore.sessionMap, authzStore.idAccessTokenMap, authzStore.expendedTokenMap, op.authSessionMap, clients.registrationsMap SQL definitions to select only expired records from the respective tables when the Infinispan purge task runs.

Resolved issues

The expired entry reaper in Connect2id server deployments with an SQL database must not terminate when an unchecked exception is encountered during an SQL select or delete query. The exception must be swallowed and an appropriate error logged (issue sql-store/31, sql-store/32).
The infinispan-replication-*.xml configurations must not use passivation for sessionStore.sessionMap and sessionStore.subjectMap as this is incompatible with shared cache stores (issue server/943).
Reduces and aligns the memory max-count limits in the infinispan-*-local-h2.xml configurations (issue server/944).
The page LIMIT in the SQL select query run by the purge task must be inlined (issue sql-store/29).

14.9 (2023-11-13)

Summary

Connect2id server deployments with an AWS DynamoDB receive rate limiting of the paged scan and delete requests that purge the database of expired subject sessions. This enhancement guards regular requests to DynamoDB from potentially being starved of their provisioned database read and write capacity when a purge scan is taking place. Moderating the purge scans may also smooth spikes in DynamoDB consumption over time and thus enable the provisioned capacity to be lowered to save costs.

Note, in deployments where native DynamoDB TTL expiration is enabled for the subject sessions, by setting the "dynamodb.enableTTL.sessionStore.sessionMap" Java system property to true, the sessions will be expired automatically by DynamoDB and the Connect2id server doesn't need to run purge scans on the sessions table. The TTL expiration suits Connect2id server deployments that have no OpenID relying parties registered to receive logout and session expiration notifications. Such notifications can be generated only when the sessions are expired by the Connect2id server itself.

Configuration

/WEB-INF/infinispan-*-dynamodb.xml
- Upgrades the dynamodb schema to v2.1.
/WEB-INF/infinispan-*-{stateless|replication}-dynamodb.xml
- Scan and delete requests that purge the sub_sessions table of expired subject sessions are rate limited to 10% of the reported provisioned read capacity for the table. For example, if the table is provisioned with 100 read capacity units, the consumed purge scan read and delete operations will be rate-limited to 10 capacity units.
  
  To specify a different value set the "dynamodb.purgeMaxReadCapacity" Java system property to the desired maximum read capacity units that may be consumed during a purge, as an absolute value, e.g. 20, or as a percentage of the current provisioned read capacity of the table, e.g. 20%. Any write capacity consumed to delete expired items is bounded by the "dynamodb.purgeMaxReadCapacity" and will always stay below it. The default value of "dynamodb.purgeMaxReadCapacity" is 10%, as explained above.

Resolved issues

The expired entry reaper in Connect2id server deployments with an AWS Dynamo database must not terminate when an unchecked parse or another exception is thrown when parsing a retrieved DynamoDB item. This may occur in DynamoDB items manipulated outside the Connect2id server APIs. Instead, the exception must be swallowed and an error with the offending item logged. This is now done with a DS0152 log error (issue dynamodb-store/21).
The *.dynamoDB.deleteTimer metrics must include DynamoDB delete requests performed as part of purges of expired items (issue dynamodb-store/22).
Removes legacy comma separator support in Scope.parse(String) (issue oidc-sdk/445).

14.8.3 (2023-11-08)

Resolved issues

Fixes a bug introduced in v14.8.1 that affects Connect2id server deployments with an SQL database. The bug resulted in repeat duplicate SQL delete queries when purging expired records in the database, causing excessive slowdown of the purge task in SQL tables with many expired records, such as records for subject sessions (issue server/938, sql-store/25).
The *.sqlStore.deleteTimer metrics must include SQL delete queries performed as part of purges of expired records (issue sql-store/26).

14.8.1 (2023-11-02)

Resolved issues

Updates the expired entry reaper for Connect2id server deployments with an SQL database to conserve memory by employing paged key set seek, in sets of up to 100 SQL records and interleaving the record deletion between the pages. Intended to prevent OOM errors in deployments with a very large number of sessions and other expiring objects (issue server/935).
Optimises the dataSource.createTableIfMissing implementation for Oracle Databases when the queried table has a very large number of records, causing Connect2id server startup to pause for times longer than 1 minute at startup. The issue is addressed by switching from LIMIT 0 to LIMIT 1 in the query to obtain the table's column names (issue server/933).
The expired entry reaper in Connect2id server deployments with an SQL database must not terminate when an unchecked parse or another exception is thrown when parsing a retrieved SQL record. This may occur in SQL records manipulated outside the Connect2id server APIs. Instead, the exception must be swallowed and an error with the offending SQL record logged. This is now done with an IS0141 log error (issue sql-store/23).
Fixes the default value and parsing of the optional sessions form parameter of the /session-store/rest/v2/purge resource (issue session-store/95).

14.8 (2023-10-20)

Summary

Implements configurable replay prevention of "client_secret_jwt" and "private_key_jwt" client authentication JWT assertions based on the optional JWT ID ("jti") claim. The implementation is based on the new expended token registry introduced in Connect2id server 14.0.
Updates the PostgreSQL configuration to enable setting of a JDBC "schema" parameter. Intended for Connect2id server deployments that want to use a database schema other than the default "public".

Configuration

/WEB-INF/oidcProvider.properties
- op.token.authJWTPreventReplay -- New optional configuration property. If true replay of "client_secret_jwt" and "private_key_jwt" client assertions will be prevented, by caching the JWT "jti" claim for the duration of the assertion lifetime but no longer than 5 minutes. The default value is true.
- op.token.authJWTExpMaxAhead -- New optional configuration property. Sets the maximum allowed number of seconds of the expiration time (exp) claim in "client_secret_jwt" and "private_key_jwt" client assertions ahead of the current time. Assertions with longer expiration time will be rejected with an invalid_client error. If zero or negative this check is disabled. When enabled the value must be between 10 and 600 seconds. The default value is -1 (disabled).
/WEB-INF/infinispan-*-postgres95.xml
- dataSource.databaseSchema -- New optional Java system property to set the PostgreSQL schema to use. Corresponds to the HikariCP "schema" configuration property. The default value is empty (implies the default "public" PostgreSQL schema).

Web API

/par
- Requests with "client_secret_jwt" and "private_key_jwt" authentication will be prevented from replaying a used JWT assertion, unless the JWT assertion is missing the optional the JWT ID (jti) claim or the replay prevention is disabled by setting the op.token.authJWTPreventReplay configuration property to false.
/token
- Requests with "client_secret_jwt" and "private_key_jwt" authentication will be prevented from replaying a used JWT assertion, unless the JWT assertion is missing the optional the JWT ID (jti) claim or the replay prevention is disabled by setting the op.token.authJWTPreventReplay configuration property to false.
/token/introspect
- Requests with "client_secret_jwt" and "private_key_jwt" authentication will be prevented from replaying a used JWT assertion, unless the JWT assertion is missing the optional the JWT ID (jti) claim or the replay prevention is disabled by setting the op.token.authJWTPreventReplay configuration property to false.

Resolved issues

Updates the authz-session log INFO "OP2101" and "OP2103" messages to include the current issuer URL when issuer aliasing is enabled (issue server/925).
Updates the authz-session log DEBUG "OP2130" and WARN "OP2131", "OP2132" messages to include the authorisation session ID (issue server/925).

Summary

The support for native applications is updated to enable registration of redirection http URIs with a loopback IP. Native applications with a localhost or loopback http redirection URI may also use a variable port, in cases when the application is not guaranteed to be able to bind to a predetermined port.
The Connect2id server can now be configured to load only selected signing keys from a PKCS#11 (HSM) store. This can enable deployments where the HSM is shared with other applications.
The Connect2id server /jwks.json endpoint may include public-only signing keys, for historical or other purposes.
The Infinispan configuration supports the setting of custom expiration intervals for all Connect2id server objects that require expiration. The expiration interval of subject sessions remains separately configurable. This enables strategies such as:
- Dedicating a set of Connect2id server nodes to processing OAuth 2.0 and OpenID Connect requests and one (or more) nodes to the task of object expiration.
- Disabling the periodic execution of the subject session expiration task and invoking it externally, for example by a cron-style job at a time that is deemed optimal.

Configuration

/WEB-INF/jwkSet.json
- The JWK set may include JWK instances without private parameters. These keys will be published at the /jwks.json endpoint and not used internally by the Connect2id server.
  
  Public signing and encryption Connect2id server keys may be included to be published at the /jwks.json endpoint for historical purposes.
/WEB-INF/federationJWKSet.json
- The federation entity JWK set may include JWK instances without private parameters. These keys will be included in issued Entity Configurations and not used internally by the Connect2id server.
  
  Public signing federation entity keys may be included for historical purposes.
/WEB-INF/jose.properties
- pkcs11.keyIDs.* -- New optional configuration property. Specifies an explicit list of identifiers (aliases) of PKCS#11 keys to load from the HSM device (when an HSM is configured). If omitted or blank all recognised keys will be loaded.
  
  This configuration property can be used to filter the PKCS#11 keys to load from an HSM that is shared by several applications.
/WEB-INF/sessionStore.properties
- sessionStore.sessionMap.expirationInterval -- Increases the default value from 300000 ms (5 minutes) to 600000 ms (10 minutes).
- sessionStore.internal.subjectIndexPurgeInterval -- Receives a new default value of -1 (disabled).
/WEB-INF/infinispan-*.xml
- Adds a new "infinispan.defaultExpirationInterval" configuration property with a default value of 300000 ms (5 minutes) to enable override of the default expiration purge interval for all Infinispan maps and caches where an expiration is required by the Connect2id server. Non-expiring maps and caches are not affected by this configuration property. The session map expiration interval override remains in the "sessionStore.sessionMap.expirationInterval" configuration property.
/WEB-INF/infinispan-stateless-{mysql|oracle|postgres95|sqlserver}.xml
- Enabled for the "sessionStore.sessionMap.expirationInterval" configuration property.
/WEB-INF/infinispan-multitenant-stateless-{mysql|oracle|postgres95|sqlserver}.xml
- Enabled for the "sessionStore.sessionMap.expirationInterval" configuration property.

Web API

/clients/
- Native applications (with the application_type metadata parameter set to native) may register redirection URIs with a loopback IP address -- 127.0.0.1 in IPv4 and 0:0:0:0:0:0:0:1 (short form ::1) in IPv6. Previously clients using the loopback interface to receive OAuth 2.0 redirections could only register with the "localhost" hostname in the URL.
- Native applications (with the application_type metadata parameter set to native) may register localhost and loopback IP redirection URIs with a variable port, by specifying port zero in the URI, for example http://localhost:0/callback. Authorisation requests can then use any port in the 1 to 65535 range, provided the other components in the redirection URI match the registered URI exactly. Example permitted redirection URI for on the given registered example: http://localhost:1234/callback.
/session-store/rest/v2/
- The /purge resource is updated, changing the default action to force a purge of the expired session only. The purging of expired and orphaned index keys is redundant and become optional operations now.
  
  Changes to the resource:
  - Adds a new form parameter with name sessions and a default value true. When true all expired sessions will be purged. When false the expired sessions purge will be skipped.
  - Adds a new form parameter with name index and a default value false. When true all expired subject index keys will be purged. When false the expired subject index keys purge will be skipped.
  - Adds a new form parameter with name orphaned_index_keys and a default value false. When true all orphaned subject index keys will be purged. When false the orphaned subject index keys purge will be skipped.
  - Adds a new form parameter with name async and a default value false. When true the purges will be performed asynchronously.
  - The async query parameter of the /purge resource is deprecated. Use the new async form parameter instead.

Resolved issues

The default value of sessionStore.internal.subjectIndexPurgeInterval is changed to -1 (disabled). In most practical cases the periodic purge task is redundant, due to the automatic subject index max_life expiration (in deployments with DynamoDB or Redis) or the purge on new subject session insertion when the subject session quota is reached. The session store /purge resource remains available (issue session-store/91).
Changes the SS0233 log message to level WARN when the purged number of orphaned subject keys is greater than zero, otherwise the level remains INFO (issue session-store/90).
Fixes an issue affecting grant isolation at the token endpoint when the Connect2id server is configured with issuer aliasing in mode PERSISTED_GRANT_ISOLATION (issue server/923).

14.5 (2023-09-03)

Web API

/clients
- Prevents registration of clients with "redirect_uris" that include a "code", "state" or "response" query parameter. OAuth 2.0 generally allows a client "redirect_uri" to include query parameters, which may be used, for instance, to process authorisation responses from multiple OAuth 2.0 servers or OpenID providers. This is a security measure that follows a recent recommendation that clients must not include query parameters in a registered "redirect_uri" with names used by the OAuth 2.0 authorisation response.
/authz-sessions/rest/v3/
- The authorisation session object (obtainable via an HTTP GET request) receives an optional "auth_req.max_age" member of type array to represent the maximum authentication age in OpenID authentication requests.
- The authorisation session object (obtainable via an HTTP GET request) receives an optional "auth_req.acr_values" member of type array to represent the Authentication Context Class Reference values in OpenID authentication requests.
- The authorisation session object (obtainable via an HTTP GET request) receives an optional "auth_req.login_hint" member of type string to represent the login hint in OpenID authentication requests.
- Rejects OAuth 2.0 authorisation and OpenID authentication requests with a "redirect_uri" that includes a "code", "state" or "response" query parameter with an "invalid_request" error. Redirection URIs with query parameters that match the name of an OAuth 2.0 authorisation response parameter are deemed unsafe. Clients that use such query parameters in a "redirect_uri" must re-register with a new compliant redirection URI.

14.4 (2023-08-11)

Summary

Connect2id server deployments that implement OAuth 2.0 Rich Authorisation Requests (RAR) (RFC 9396) can use a new "op.rar.supportedTypes" configuration property to let the server check the types of "authorization_details" in received requests and reject requests with unsupported RAR types. The supported types will also be advertised in the "authorization_details_types_supported" OpenID provider metadata field.
Connect2id server deployments with an embedded H2 database are upgraded from 2.1.x to the latest stable 2.2.x release. Database files created in the older H2 version are not compatible. Existing records (where they must be retained) must be migrated.

Configuration

/WEB-INF/oidcProvider.properties
- op.rar.supportedTypes -- New optional configuration property to list the supported OAuth 2.0 Rich Authorisation Request (RAR) (RFC 9396) types. When specified the "authorization_details" in OAuth 2.0 authorisation / OpenID authentication requests and token requests will be checked and those with an unsupported type will be rejected with an "invalid_authorization_details" error. The types will also be advertised in the "authorization_details_types_supported" OpenID provider metadata field. The default value is none (no check).

Web API

/.well-known/openid-configuration
- authorization_details_types_supported -- New optional metadata field listing the supported OAuth 2.0 Rich Authorisation Request (RAR) (RFC 9396) types. Omitted if not specified.
/authz-sessions/rest/v3/
- The authorisation session object (obtainable via an HTTP GET request) receives an optional "auth_req.authorization_details" member to represent the Rich Authorization Request (RAR) (RFC 9396) parameter in OAuth 2.0 authorisation requests and OpenID authentication requests.

Resolved issues

The UserInfo endpoint must not request claims from the sourcing SPI that are pre-set (e.g. supplied via "preset_claims.userinfo" in the authorisation session API) (issue server/885).
Updates JWT minting to support the inclusion of null-valued top-level claims, which can legitimately occur in data returned from the claims source SPI. The claims set in plain (unsecured) UserInfo responses and JWT-secured UserInfo responses will thus be identical for those cases when claims with null values are included, previously omitted in a JWT (issue server/906).
The "authorization_details" parameter must be obtainable in the AuthorizationRequestValidator and PARValidator SPIs (issue server/907).

14.3 (2023-08-07)

Summary

Connect2id server 14.x deployments with a Redis store should update to this release which fixes an issue related to ProtoBuf marshalling.
The OAuth 2.0 / OpenID Connect SDK dependency was updated to v10.13.2 which includes native OAuth 2.0 Rich Authorisation Requests (RAR) (RFC 9396) support. CustomTokenResponseComposer SPI plugins that implement RAR should be recompiled and updated if feasible to utilise the new type-safe methods of AccessTokenResponse when adding an "authorization_details" parameter to the response.

Built-in RAR support is on the Connect2id server roadmap and will be included in a future release.

Configuration

/WEB-INF/oidcProvider.properties
- op.reg.clientIDByteLength -- Updates the configuration property check, the length of generated client identifiers must not exceed 48 bytes.

Resolved issues

14.0 (2023-06-27)

Summary

Support for refresh token rotation on an individual authorisation basis, overriding the global Connect2id server configuration.

Self-contained (JWT-encoded) refresh tokens, which are linked to transient / non-persisted ("long_lived":false) authorisations, also receive the ability to be rotated.

Previously refresh token rotation could only be set globally and apply only to identifier-based refresh tokens, which are linked to long-lived / persisted ("long_lived":true) authorisations.
Support for ID token refresh at the token endpoint, settable on an individual authorisation basis. The token response will include a new ID token when the refresh token authorisation allows such refresh and the subject (end-user) session bound to the refresh token is still present. If the session was closed or expired no ID token will be included in the token response.

An authorised OpenID relying party may use the ID token refresh to do a back-channel check whether the end-user session with the OpenID provider still exists (i.e. that the session wasn't closed or expired). OpenID relying parties should use the standard "prompt=none" OpenID authentication request to ensure the end-user is actively present and properly authenticated, since this method involves the front-channel (the browser). An ID token refresh thus isn't equivalent to or a substitute for a "prompt=none" OpenID authentication request.
Public clients registered for OAuth 2.0 mutual TLS (RFC 8705) and the OAuth 2.0 refresh token grant will receive refresh tokens that are client X.509 certificate bound.
Allows registration of native applications (the client "application_type" metadata field set to "native") with non-localhost https redirection URIs, e.g. https://app.example.com/callback.
Introduces "urn:c2id:introspection_endpoint" as alternative fixed scope value for authorising access to the token introspection endpoint of the Connect2id server. Authorisations with a scope value set to the token introspection endpoint, e.g. https://op.example.com/token/introspect continue to be supported. The fixed scope value is intended for introspecting clients registered in Connect2id server deployment configured with OP / AS issuer aliases.
A new "op.authz.limitScopeToRegistered" configuration property to filter the requested scope values in the consent prompt of the authorisation session API to those registered in the metadata of the requesting client. If disabled or no "scope" client metadata field is registered, the authorisation request scope will be passed to the consent prompt as it is. Enabled by default.
The Connect2id server configuration properties were revised and given appropriate default values where applicable. Intended to reduce the configuration effort and the number of Java system properties necessary to deploy a Connect2id server.
Updates the TokenIntrospectionResponseComposer SPI to provide access to the subject (end-user) session where the token consent occurred, when the session is still present (not closed or expired). The subject session may be used by customised token introspection endpoints to include selected claims or other details from the session in the introspection responses.
Updates the AdvancedClaimsSource SPI to provide access to the subject (end-user) session where the claims sourcing was authorised, provided the session is still present (not closed or expired). The subject session may be used to source claims for UserInfo responses and ID tokens.
A Software Bill Of Materials (SBOM) in CycloneDX JSON and XML format is included in the c2id.war under /WEB-INF/sbom/CycloneDX-Sbom.json and /WEB-INF/sbom/CycloneDX-Sbom.json
Upgrades to Infinispan 14.0.

Due to the switch of the internal object serialisation in Infinispan to Protocol Buffers (Protobuf) existing in-memory data in Connect2id server 13.x deployments in replication cluster mode or with Redis as in-memory data and cache store will not be recognised and hence ignored by a Connect2id server v14.0 deployment. If such in-memory data (subject sessions, etc.) needs to be preserved it must be manually migrated.
Adds Oracle 12c r1+ Database support.
Removes LDAP backend database support as part of the Infinispan 14.0 upgrade. Connect2id server deployments with an LDAP backend database can migrate to a supported SQL RDBMS or to AWS DynamoDB.

/WEB-INF/infinispan-*-{mysql|postgres95|sqlserver|oracle|h2}.xml
- New optional "dataSource.createTableIfMissing" Java system property. When "true" (the default value) the Connect2id server will automatically create the required SQL tables on startup. It will also perform automatic table alternations where necessary in new major releases. When "false" the database administrator must create or alter the tables manually before server startup.
- New optional "dataSource.maxPoolSize" Java system property. Controls the maximum size the SQL connection pool is allowed to reach, including both idle and in-use connections. The default size is 5.
- Upgrades the SQL schema (the Connect2id server will automatically add the new table and columns on startup unless "dataSource.createTableIfMissing" is disabled):
  - Adds an "expended_tokens" table.
  - Adds a "sik" (session identifier key) column to the "id_access_tokens" table.
  - Adds an "idr" (ID token rotate) column to the "long_lived_authorizations" table.

/token
- Supports issue of rotated self-contained (JWT-encoded) refresh tokens.
- Supports ID token refresh. Requires the refresh token authorisation to explicitly allow ID token refresh and the subject (end-user) session bound to the refresh token to be still present (not closed or expired), else an ID token will not be included in the token response.
  
  The expiration of the refreshed ID token will be set according to the globally configured "op.idToken.defaultLifetime". An ID token lifetime supplied to the consent object (with "id_token.lifetime") will not be replicated in refreshed ID tokens.
  
  The "max_age" OpenID authentication request parameter will trigger inclusion of the "auth_time" claim only in the ID token issued in the direct response to it, not in refreshed ID tokens. For an OpenID relying party to receive the "auth_time" claim in refreshed ID tokens it must be registered as client for the "require_auth_time" metadata parameter.
  
  The refreshed ID token will include all consented claims as well as any claims found in the subject session "claims" field (unless the "op.authz.feedSubjectSessionClaimsIntoIDToken" configuration property prevents this). Preset ID token claims supplied to the consent object (with "preset_claims.id_token") will not be replicated in refreshed ID tokens.
/token/introspect
- Introduces "urn:c2id:introspection_endpoint" as alternative fixed scope value for authorising access to the token introspection endpoint of the Connect2id server.
/authz-sessions/rest/v3/
- Adds an optional "refresh_token.rotate" parameter of type boolean to the consent object. Sets the refresh token rotation for the current authorisation. When omitted the "authzStore.refreshToken.defaultRotate" configuration will apply.
- Adds an optional "id_token.allow_refresh" parameter of type boolean to the consent object. Allows an OpenID relying party to receive a new ID token at the token endpoint in exchange for a valid refresh token, with the subject session bound to the refresh token still being present.
/direct-authz/rest/v2/
- Adds an optional "refresh_token.rotate" parameter of type boolean to the request object. Sets the refresh token rotation for the individual authorisation. When omitted the "authzStore.refreshToken.defaultRotate" configuration will apply.
- Adds an optional "id_token.allow_refresh" parameter of type boolean to the request object. Allows an OpenID relying party to receive a new ID token at the token endpoint in exchange for a valid refresh token, with the subject session bound to the refresh token still being present.
- Adds an optional "claims_data" parameter of type JSON object to the request object. The parameter will be passed in the request to retrieve the consented OpenID claims from the configured source(s). The claims data will be included in a "cld" (claims data) field in the issued access token(s) and in the long-lived authorisations if the consent is persisted. If the claims data must be kept confidential from the client either an identifier access token encoding must be chosen or if a self-contained (JWT) access token is chosen it must be additionally encrypted. An AdvancedClaimsSource SPI implementation can retrieve the claims data JSON object by a call to the "ClaimsSourceRequestContext.getClaimsData" method.
  
  This parameter is identical to the "claims_data" parameter in the consent object of the authorisation session web API.
/authz-store/rest/v3/
- New "rtr" authorisation field of type boolean for the refresh token rotate setting. The default value is false.
- New "idr" authorisation field of type boolean for the allow ID token refresh setting. The default value is false.
- Removes the "/config" resource for retrieval (via HTTP GET) of the public authorisation store configuration.
/monitor/v1/metrics
- Adds new "authzStore.numExpendedTokenEntries" gauge.
- Removes the "clientStore.numCachedExpendedTokens" gauge (replaced by the new "authzStore.numExpendedTokenEntries" gauge).

SPI

Upgrades the Connect2id server SDK to com.nimbusds:c2id-server-sdk:4.58
- The RefreshTokenSpec class receives a new optional rotation setting. If empty the default Connect2id server refresh token rotation policy will apply.
- The IDToken spec class receives a new optional allow refresh setting. The default setting is no ID token refresh allowed.
- The PasswordGrantHandler SPI can set a refresh token rotation preference.
- The TokenExchangeGrantHandler SPI can set a refresh token rotation preference.
- The TokenIntrospectionResponseComposer SPI adds access to the subject (end-user) session used for the token consent, provided the session is still present (not closed or expired). The session object can be accessed via the "TokenIntrospectionContext.getSubjectSession" method. The subject session may be used by customised token introspection endpoints to include subject claims or other details from the session in the responses.
- The TokenIntrospectionResponseComposer SPI extends Lifecycle.
- The AdvancedClaimsSource SPI adds access to the subject (end-user) session where the claims sourcing was authorised, provided the session is still present (not closed or expired). The session object can be accessed via the "ClaimsSourceRequestContext.getSubjectSession" method.
  
  The subject session is supplied in the following cases:
  - Claims sourcing for the UserInfo endpoint where the subject session where the claims consent occurred is still present (not expired or closed);
  - Claims sourcing for ID token issue for an OAuth 2.0 authorisation code, implicit (including OpenID Connect hybrid response type) and refresh token grants;
  - Claims sourcing for a direct authorisation request where a valid subject session ID was supplied, or a new subject session was created.
  - Claims sourcing made available to the TokenIntrospectionResponseComposer SPI.
  The subject session may be used as a source of subject authentication claims, or claims from the optional "claims" session field.
- Adds an "AccessTokenAuthorization.getSubjectSessionKey" method, returns null by default. Intended to represent the new encrypted subject session ID key attribute ("sik") in access tokens. Connect2id server deployments with a custom codec (SelfContainedAccessTokenClaimsCodec SPI implementation) for the JWT claims for access tokens should update it to include the new attribute.
- The IdentifierAccessTokenCodec SPI extends Lifecycle.
- The SelfContainedAccessTokenClaimsCodec SPI extends Lifecycle.
- Removes deprecated ServiceContext interface.
- Removes deprecated InitContext.getIssuer method. Use the SPI request context getIssuer method instead.
- Removes deprecated InitContext.getOPIssuer method. Use the SPI request context getIssuer method instead.
- Removes deprecated InitContext.getTokenEndpoint method.
- Removes deprecated InitContext.getServiceContext method.

Summary

Updates to the logout session API.

Web API

/logout-sessions/rest/v1/
- Adds new "sub_session_closed" parameter to the logout-end message, of type boolean {true|false}. When true indicates the Connect2id server closed the end-user session in response to an IdP-initiated logout request, or in response to an RP-initiated logout request with a submitted end-user confirmation that included the choice to log out of the IdP as well. To be used as a hint to delete the browser cookie linked to the session. Note that the deletion of the session cookie is not critical, because the session ID is invalidated on the server side.
- The logout session API is updated to proceed with a requested "post_logout_redirect_uri" when there is no present end-user session, or the session has expired. Previously the redirection request by the relying party (RP) would be silently ignored. This change conforms with OpenID Connect RP-Initiated Logout 1.0 (see section 4).

Dependency changes

Updates to com.nimbusds:nimbus-jose-jwt:9.31

13.5 (2023-02-20)

Summary

Single sign-on (SSO) can be disabled for selected clients.
New session store web API resource for modifying the authentication lifetime of an end-user session.
Client secret store SPI plugins can return the encoded secret in client read responses with a new custom "encoded_client_secret" client metadata field.

Configuration

/WEB-INF/oidcProvider.properties
- op.sso.disableForSelectedClients -- New optional configuration property to disable single sign-on (SSO) for selected registered clients. Ensures end-users will be always (re)authenticated on the first OAuth 2.0 authorisation / OpenID authentication request when end-user has an existing session with the Connect2id server. Subsequent requests from the client received into the same end-user session will be processed as usual, without triggering re-authentication of the end-user.
  
  Disabling SSO for a client creates the effect of "virtual" client-based sessions with the Connect2id server.
  
  Clients with disabled SSO are selected by configuring a JSON query that accepts the client registration (as JSON object representation) and returns a boolean true result. The default configuration property is no selector specified.
  
  Example JSON query to disable SSO for clients which registered a custom data JSON object containing a disable_sso member set to true: .data.disable_sso==true.
  
  The Connect2id server logs the configured JSON query at INFO level with the ID OP0090.

Web API

/session-store/rest/v2/
- Adds a new /sessions/subject-auth-life resource supporting a PUT method to change the authentication lifetime of a session. The value is specified as an integer number of minutes, where -1 means infinite (no timeout) and 0 implies the default lifetime from the sessionStore.authLifetime configuration property. Returns HTTP 204 No Content on success.
/clients/
- Connect2id server deployments with a ClientSecretStoreCodec plugin for encoding (hashing or encrypting) client secrets before committing them to storage will include the stored client secret in an "encoded_client_secret" metadata field in responses to client registration read (HTTP GET) requests. Note, in order to provide the metadata field in registration read responses the ClientSecretStoreCodec.decode method must return a DecodedSecret.withEncodedValue.
/monitor/v1/metrics
- Adds new sessionStore.sessionAuthLifetimeUpdates meter.

Resolved issues

The OpenID Connect Federation 1.0 "value" policy check must support JSON objects (issue oidc-sdk/419).

Resolved issues

The "aud" of request objects (JARs) passed by OpenID Connect Federation 1.0 clients must include the OpenID provider issuer URL, not the authorisation endpoint URL (issue server/825).
Fixes a bug that prevented client metadata shaped by a FinalMetadataValidator SPI plugin from appearing in the authentication prompt message when the op.authz.includeClientInfoInAuthPrompt configuration property is set to true and the requesting client is an automatic OpenID Federation 1.0 client that was just registered (issue server/826).
The signing JWK feeder when dealing with X.509 certificate based JWKs should bias the key selection to pick the key with the farthest certificate expiration date. This is to ensure optimal roll-over of RSA and EC signing JWKs with an X.509 certificate (issue jwk-set-loader/5).
Fixes the SE2000 error log message on failing to find a signing key with a currently valid X.509 certificate (according to its not-before and not-after attributes). The message must apply to both regular (in-memory) keys with an X.509 certificate and HSM keys with a certificate (issue jwk-set-loader/4).

13.4 (2023-01-30)

Summary

Updates the Connect2id server to support the Java 17 runtime.

Due to the secp256k1 elliptic curve no longer being available in the default Java Cryptography Architecture (JCA) provider the Connect2id server will use the alternative open source BouncyCastle JCA provider for the ES256K (secp256k1 curve) JWS algorithm when it's used to secure ID tokens, UserInfo JWTs, request objects (JAR), authorisation responses (JARM) or self-contained (JWT) access tokens.

The Java 11 runtime support remains.
Adds support for registering OAuth 2.0 clients with redirect_uri templates, to enable Connect2id server deployments to set the redirection URI at the time when the authorisation request is processed.

This can facilitate scenarios where the exact redirect_uri is not known at the time of client registration or where a client may require a multitude of redirection URIs that conform to a certain pattern. The redirect_uri templates apply to authorisation requests as well as pushed authorisation requests (PAR).

Example template where the [param] is a placeholder for a parameter to be set when the Connect2id server processes the authorisation request:

urn:c2id:redirect_uri_template:https://[param].example.com/login-callback

Web API

/clients/
- Supports registration of OAuth 2.0 web and native clients with templates in the redirect_uris parameter. The template is a URN with format urn:c2id:redirect_uri_template:[URI], where URI is the final redirection URI which must contain a single [param] placeholder. The [param] placeholder will be set by the Connect2id server when it processes authorisation requests from the client.
/authz-sessions/rest/v3/
- Adds an optional redirect_uri_template_param parameter of type string to the authorisation session start request object. Used to set the [param] in a redirect_uri of an authorisation request where the URI is a template. The template URI must be registered just as any regular redirection URI in the client's record under the redirect_uris field.
  
  The [param] setting will apply to all authorisation requests, including JAR and PAR.
  
  If the Connect2id server doesn't set the [param] for some reason the redirect_uri will remain unchanged, which will later cause the redirection to fail because of the URN scheme.

13.3 (2023-01-23)

Summary

Token exchange (RFC 8693) plugins can now optionally specify the issue of a refresh token and ID token (in addition to the access token) when authorising a request received via the TokenExchangeGrantHandler SPI. The plugin can also flag the authorisation as long-lived (persisted), to cause the granted scope values and other attributes to be remembered for the subject and the requesting client. This also enables control of the refresh token encoding (if issued) - persisted or stateless.
Resource owner password credentials grant plugins can now specify the issue of stateless (JWT-encoded) refresh tokens. Previously only persisted refresh tokens could be issued.
Updates the plugin for handling OAuth 2.0 grants at an external web service (web hook) to support token exchange (RFC 8693) authorisations for refresh token and ID token issue.

Web API

/token
- Adds support for refresh token and ID token issue for a OAuth 2.0 token exchange grant (RFC 8693).

SPI

Upgrades the Connect2id server SDK to com.nimbusds:c2id-server-sdk:4.52
- The TokenExchangeAuthorization class is updated to support optional persistence of the authorisation (with the long-lived flag), issue of a refresh token (stateless or persisted) and issue of an ID token.
- The PasswordGrantAuthorization class is updated to support issue of a stateless refresh token when the long-lived authorisation flag is set to false. Previously only persisted refresh tokens could only be issued, when the long-lived authorisation flag was set to true.

Fixes two bugs affecting deployments of Connect2id server v13.0 and v13.1 with an SQL database. Updating is strongly recommended (see issue server/816 for details).

Web API

/.well-known/openid-configuration
- signed_jwks_uri -- New optional metadata field specifying an endpoint where the OpenID provider JWK set is published as a signed JWT. Available when OpenID Connect Federation 1.0 is enabled, else omitted.
/jwks.jwt -- New endpoint publishing the OpenID provider JWK set as a signed JWT when OpenID Connect Federation 1.0 is enabled. The JWT is signed with the RS256 algorithm using the first RSA key in the configured Connect2id server federation entity JWK set. The JWT typ (type) header is set to jwk-set+jwt. The JWT contains the iss (issuer), sub (subject), iat (issued-at time) and keys (JWK set keys) claims, as specified in OpenID Connect Federation 1.0, section 4.1.

Resolved issues

Fixes a bug introduced in Connect2id server 13.0, multi-tenant edition, affecting deployments with MySQL, PostgreSQL and MS SQL Server that may cause false HTTP 404 (invalid authorisation session ID) responses from the authorisation session web API. Connect2id server 13.0 and 13.1 multi-tenant deployments are strongly recommended updating (issue server/816).

13.1 (2022-12-23)

Summary

OpenID Connect Federation 1.0 upgrade.

The pushed authorisation request (PAR) endpoint is now able to handle automatic registration clients authenticating with a public key using a JWT assertion (private_key_jwt) or mutual TLS (tls_client_auth or self_signed_tls_client_auth).

The entity configuration, trust chain resolution and client registration is updated to draft 25 of the OpenID Connect Federation 1.0 specification.

See https://openid.net/specs/openid-connect-federation-1_0.html
The token introspection endpoint receives a new configuration to control the pruning of audience ("aud") values in responses.

Configuration

/WEB-INF/oidcProvider.properties
- op.token.introspection.pruneAudience -- New optional configuration property to override the default Connect2id server filtering (since v7.17 (2019-10-12)) of audience ("aud") values in token introspection responses. If true causes the audience to be pruned to the client_id of the introspecting client, intended to prevent revealing information about recipients other than the intended in multi-audience tokens. If false the complete token audience will always be shown. Has no effect on tokens that don't specify an audience. The default value is true.
- op.federation.autoClientAuthMethods.par -- New optional configuration property listing the enabled methods for authenticating OpenID Connect Federation 1.0 automatic client registration requests at the OAuth 2.0 pushed authorisation request (PAR) endpoint. Supported methods: private_key_jwt, tls_client_auth and self_signed_tls_client_auth.
- op.federation.logoURI -- New optional configuration property specifying the logo URI of the OpenID provider as an OpenID Connect Federation 1.0 entity. Will appear in the entity configuration published at the /.well-known/openid-federation endpoint, under the metadata.federation_entity.logo_uri claim.
jose.federationJWKSet -> jose.federation.jwkSet -- Renames the Java system property name for setting the OpenID Connect Federation 1.0 entity JWK set. The Java system property overrides the /WEB-INF/federationJWKSet.json JWK set file content.

Web API

/.well-known/openid-federation
- Updates the published entity configuration to OpenID Connect Federation 1.0 draft 25.
- metadata.federation_entity.logo_uri -- New optional federation entity claim, configured by the op.federation.logoURI property.
/par
- Supports OpenID Connect Federation 1.0 compliant automatic registration clients that use the private_key_jwt, tls_client_auth and self_signed_tls_client_auth methods (must be enabled in the op.federation.autoClientAuthMethods.par configuration property).
/federation/clients
- Updates explicit client registration to OpenID Connect Federation 1.0 draft 25.
/token/introspect
- Pruning of the audience ("aud") values in token introspection responses can be now be controlled by the optional op.token.introspection.pruneAudience configuration property.

Resolved issues

The PAR endpoint should clear client_secret_post, client_secret_jwt and private_key_jwt form parameter artifacts from the stored authorisation request (issue server/813).

13.0 (2022-11-30)

Summary

Individual clients can be registered to require use of Proof Key for Code Exchange by OAuth Public Clients (RFC 7636) by means of the code_challenge_method client metadata.
Upgrades the OpenID provider / OAuth 2.0 authorisation server issuer alias model.

Issuer aliasing was introduced in v12.3 (2021-09-17) to enable a Connect2id server deployment to migrate seamlessly and over time from one issuer identifier URL to another. Issuer aliases can also be used when an OpenID provider / OAuth 2.0 authorisation server is known by multiple URLs.

This release introduces two differentiated issuer alias modes (configurable by op.issuerAliasMode):
- MIGRATION -- Intended to facilitate issuer URL migration or deployments where the OpenID provider is known by multiple URLs. This is the default mode and how the Connect2id server previously behaved with enabled issuer aliases.
- PERSISTED_GRANT_ISOLATION -- Enforces complete OAuth 2.0 grant isolation between issuer aliases. Has the effect of disabling long-lived (persisted) consent, forcing issue of self-contained (stateless) refresh tokens only, and blocking the use of any previously issued identifier-based refresh tokens. This mode is intended for deployments that for some reason choose not to operate a multi-tenant Connect2id server where the OpenID providers / OAuth 2.0 authorisation servers completely isolated.
For security reasons both issuer alias modes will now behave as follows:
- Prevent switching of the issuer URL during an OAuth authorisation code, implicit or hybrid flow (which may involve the PAR endpoint).
- Prevent switching of the issuer URL in the authorisation session API at the user authentication or consent step.
- The token introspection endpoint will mark any token issued under a different alias as invalid and the scope to access the endpoint must also be set to the current issuer URL.
- The UserInfo endpoint will reject access tokens issued under a different alias.
Note, in the MIGRATION issuer alias mode refresh tokens which are tied to long-lived (persisted) consent can be shared across all issuer aliases. The resulting access tokens however will be issued and remain valid for the current issuer alias only.

Finally, the issuer aliasing was updated to enable dynamic addition and removal of issuer alias URLs, with no changes to the Connect2id server configuration.
Upgrades H2 SQL database support from v1.x to v2.x. This is a breaking change that affects the persisted H2 data format. Data stored by H2 v1.x is not compatible and cannot be read by H2 v2.x. Connect2id server deployments that use H2 to persist server data will need to perform a migration. See the Data Migration guide for more information.

Configuration

/WEB-INF/oidcProvider.properties
- op.issuerAliases -- New optional configuration property for Connect2id server deployments that need to support issuer alias URLs of the OpenID provider / OAuth 2.0 authorisation server. By setting the configuration property to "*" (asterisk) the HTTP reverse proxy in front of the Connect2id server is enabled to determine the whitelisted issuer alias URLs when setting the "Issuer" security header. This can be useful in deployments where issuer aliases must be added or removed dynamically, without restarting the server (in the regular edition) or updating the OpenID provider / OAuth 2.0 authorisation server configuration via the tenants web API (in the multi-tenant edition). Previously the Connect2id server supported only a static whitelist of allowed issuer aliases.
- op.issuerAliasMode -- New optional configuration property introducing two differentiated modes of issuer aliasing:
  - MIGRATION -- Enables seamless migration over time to a new issuer URL. This is the default mode and how the Connect2id server previously behaved with enabled issuer aliases.
  - PERSISTED_GRANT_ISOLATION -- Enforces persisted grant isolation between issuer aliases: disables long-lived (persisted) consent; forces issue of self-contained (stateless) refresh tokens; blocks the use of any previously issued identifier-based refresh tokens.
- op.reg.httpMaxRequestSize -- New optional configuration property enabling override of the size limit of the entity body of HTTP POST and PUT requests to the client registration web API. Configurable via Java system property only! The default value is 250 thousand (250000) characters.
/WEB-INF/infinispan--redis-.xml
- New redisMapPassword and redisCachePassword configuration properties of type string to set a password for accessing Redis. The default value is no password.
/WEB-INF/infinispan-*-{mysql|postgres95|sqlserver|h2}.xml
- Adds new "code_challenge_method" column to the "clients" table. In existing Connect2id server deployments with an SQL RDBMS the server will automatically add the new column (with an appropriate default value) on startup.
/WEB-INF/infinispan-*-ldap.xml
- Adds new "oauthCodeChallengeMethod" attribute to the "oauthClientMetadata" object classes. Connect2id server deployments with an LDAP v3 backend database (such as OpenLDAP or OpenDJ) must update the LDAP schema manually to version 1.19 see https://bitbucket.org/connect2id/server-ldap-schemas/src/1.19/ , the OpenLDAP schema diff https://bitbucket.org/connect2id/server-ldap-schemas /diff/src/main/resources/oidc-client-schema-openldap.ldif?at=1.19 &diff2=97f372ce82ddd94e08a3937c4169f3a190aed2b2 and the OpenDJ schema diff https://bitbucket.org/connect2id/server-ldap-schemas /diff/src/main/resources/oidc-client-schema-opendj.ldif?at=1.19 &diff2=97f372ce82ddd94e08a3937c4169f3a190aed2b2

Web API

/clients
- Supports registration of clients with the optional custom code_challenge_method metadata field of type string and values S256 and plain to force the client to use a code challenge method (see Proof Key for Code Exchange by OAuth Public Clients, RFC 7636) at the authorisation and the pushed authorisation request (PAR) endpoints. The default value is no code challenge method.
  
  Note that the Connect2id server op.authz.allowedPKCE and op.authz. requiredPKCE configuration properties will always override this client metadata.

Resolved issues

Upgrades the security of the authorisation code grant at the token endpoint by adding an immediate code invalidation to complement the usual invalid_grant OAuth 2.0 error in the following cases: 1) mismatch between token request client_id (for a public or successfully authenticated confidential client) and the client_id associated with the issued code at the authorisation endpoint; 2) invalid or missing redirect_uri; 3) missing, invalid or unexpected code_verifier (PKCE); 4) mismatch between the code issuer and the tenant issuer at the token endpoint (issue authz-store/195).
Improves the data layer performance of code for token exchange at the token endpoint (issue authz-store/195).
Updates the token endpoint unauthorized_client error description in the case when the request is rejected because the client is not registered for the grant type (issue server/798).

12.18 (2022-10-25)

Configuration

/WEB-INF/oidcProvider.properties
- op.metadataOverlay -- New optional configuration property for a JSON object overlay to apply to the OpenID provider / OAuth 2.0 authorisation server metadata published at the ".well-known/openid-configuration" and ".well-known/oauth-authorization-server" endpoints. Non-null values in the overlay object replace existing metadata fields, null values remove them. Note, the overlay does not affect the internal Connect2id server configuration and after its application the resulting JSON object is not checked for being a legal representation of OpenID provider / OAuth 2.0 authorisation server metadata. If set the overlay must be represented as a JSON object string, and can be additionally BASE64 encoded to ease passing the configuration property from a command line shell.

- Adds support for an optional "quiet" query parameter when posting a revocation. When set to quiet=true an HTTP 204 No Content response will be returned; if any authorisation(s) were matched by the revocation parameters and removed they will not be returned in the response body.

Resolved issues

The authorisation session web API must not set the "required_sub" parameter in the authentication prompt to the end-user ID when the Connect2id server is configured with alwaysPromptForAuth=true and the end-user has an active session. This resulted in a incorrect OpenID Connect login_required error if the current end-user is (re)authenticated to another subject (end-user ID) as a result of the authentication prompt. The fix corrects the behaviour so that the original session is closed and a new one with the new subject (end-user ID) is started (issue server/781).
The op.grantHandler.tokenExchange.webAPI.actorToken.types configuration property of the token exchange grant handler plugin must support setting of no actor token types accepted. The default value must also be none (issue grant-handlers-web/1).

12.16 (2022-08-12)

Summary

Adds new plugin for handling OAuth 2.0 token exchange (RFC 8693) grants that passes processing of the grant authorisation to an external web service (web hook). The plugin implements the TokenExchangeGrantHandler SPI introduced in Connect2id server 12.14.

Features:
- Supports arbitrary "subject_token" and "actor_token" types.
- The acceptable "subject_token", "actor_token" and requested token types are configurable.
- Optional automatic introspection of the received "subject_token" of type access token. Calls upon the internal Connect2id server introspection for access tokens that are locally issued, or one or more configured token introspection endpoints compliant with RFC 7662.
- Optional automatic JWT verification of the received "subject_token" of type JWT, access token or ID token. The JWT signature is verified using a set of JWKs at one or more configured URLs.
- Received "subject_token" and "actor_token" instances can also be passed in their original form for verification by the web service itself.
- Supports passing of selected client metadata parameters to the web service, in addition to the client_id and confidential status, to be used as inputs in the authorisation decision. The "scope" and "data" client metadata fields are included by default.
- Supports setting of HTTP connect and read timeouts, for the underlying web service, the configured token introspection endpoints and JWK set URLs.
Replaces the existing plugin for handling OAuth 2.0 client credentials grants at an external web service (web hook) with a new one that enables configuration of the client metadata fields to pass to the handler. Also supports multi-tenant operation.
Replaces the existing plugin for handling OAuth 2.0 resource own password credentials grants at an external web service (web hook) with a new one that enables configuration of the client metadata fields to pass to the handler. Also supports multi-tenant operation.

Configuration

/WEB-INF/tokenExchangeGrantHandlerWebAPI.properties -- New configuration file for the new web-based token exchange grant handler, containing the default configuration properties. They can be selectively overridden with Java system properties.
/WEB-INF/clientGrantHandlerWebAPI.properties
- op.grantHandler.clientCredentials.webAPI.customParams -- New optional configuration property to list the names of custom token request parameters to include as top-level members in the handler request JSON object.
- op.grantHandler.clientCredentials.webAPI.clientMetadata -- New optional configuration property to list the names of client metadata fields to include in the "client" JSON object which is part of handler request. If not specified the following client metadata fields are included by default: "scope", "application_type", "sector_identifier_uri", "subject_type", "default_max_age", "require_auth_time", "default_acr_values", "data"
/WEB-INF/passwordGrantHandlerWebAPI.properties
- op.grantHandler.clientCredentials.webAPI.customParams -- New optional configuration property to list the names of custom token request parameters to include as top-level members in the handler request JSON object.
- op.grantHandler.clientCredentials.webAPI.clientMetadata -- New optional configuration property to list the names of client metadata fields to include in the "client" JSON object which is part of handler request. If not specified the following client metadata fields are included by default: "scope", "application_type", "sector_identifier_uri", "subject_type", "default_max_age", "require_auth_time", "default_acr_values", "data".

Web API

/authz-sessions/rest/v3/
- Designates the "invalid_target" OAuth 2.0 error code, defined in RFC 8707, as a standard acceptable code to indicate an error condition during end-user authentication / consent. Deployments that use this error code are no longer required to list it in the op.authz. customErrorCodes configuration.

SPI

Upgrades the Connect2id server SDK to com.nimbusds:c2id-server-sdk:4.51

Summary

Updates OpenID Connect RP-Initiated Logout 1.0 support to draft 02. Introduces new logout_hint, client_id and ui_locales request parameters. See https://openid.net/specs/openid-connect-rpinitiated-1_0.html
PrivateKeyJWTCertificateVerifier SPI plugins can override the default error_description and error_uri in invalid_client errors returned to the authenticating OAuth 2.0 client.
New dynamodb.enableContBackups configuration property to enable DynamoDB continuous backups / point-in-time recovery for tables holding crucial or long-lived Connect2id server data. Previously continuous backups could be enabled only via the AWS CLI, SDK, API or web console.

Configuration

/WEB-INF/infinispan-*-dynamodb.xml
- New dynamodb.enableContBackups configuration property of type boolean (true|false) to enable continuous backups / point-in-time recovery for all DynamoDB tables where crucial or long-lived Connect2id server data is persisted: id_access_tokens, long_lived_authorizations, revocation_journal, clients, federation_clients and tenants (in the multi-tenant Connect2id server edition). Applied at Connect2id server startup on new table creation as well as for existing tables. The default value is false (no continuous backups).

Web API

Logout (end-session) endpoint
- id_token_hint -- Relying parties can submit ID token hints encrypted with JSON Web Encryption (JWE) for confidentiality. The ID token can be encrypted with a public encryption RSA or EC JWK published at the Connect2id server's jwks.json endpoint. A relying party that is provisioned with a client_secret can alternatively encrypt the ID token with a symmetric AES key using the JWE dir algorithm and a JWE method listed in the id_token_encryption_enc_values_supported OpenID provider metadata field, as specified in OpenID Connect Core 1.0 incorporating errata set 1, section 10.2.
- client_id -- New optional RP-initiated logout request parameter, of type string, representing the client ID of the relying party. A relying party should use it to identify itself in a request when the recommended id_token_hint parameter isn't included or when the id_token_hint represents a symmetrically encrypted (JWE) ID token so the OpenID provider can resolve the relying party's registered client_secret necessary for the ID token decryption. If both id_token_hint and client_id are included in a logout request the client ID must be found in the ID token audience.
  
  Note, a valid id_token_hint remains required for RP-initiated logout requests that include a post_logout_redirect_uri parameter.
- logout_hint -- New optional RP-initiated logout request parameter, of type string, representing a hint about the end-user that is logging out, such as the user's email address, telephone number or username. Analogous to the login_hint OpenID authentication request parameter.
- ui_locales -- New optional parameter, of type string and consisting of one or more space delimited BCP47 (RFC 7231) language tags, representing the end-user's preferred languages and scripts for the logout UI.
/logout-sessions/rest/v1/
- Adds support for the optional client_id RP-initiated logout request parameter. The Connect2id server will use it to identify the calling relying party when the recommended id_token_hint logout request parameter isn't included or represents an ID token that is symmetrically encrypted with a client_secret. If both id_token_hint and client_id are present in a logout request the Connect2id will check the ID token was issued to the client_id; if not an invalid_id_token_hint error will be returned.
- New id_token_hint_present parameter in the logout prompt message, of type boolean (true|false), to show if the relying party included an id_token_hint in the logout request.
  
  Note, if the id_token_hint logout request parameter failed the Connect2id server verification (covers all standard ID token checks, save for its exp claim), the logout session API will return an invalid_id_token_hint error. Hence, the id_token_hint_present when true will always indicate a valid ID token.
- New optional op_logout parameter in the logout confirmation message, of type boolean (true|false) and a default value false, to indicate an end-user request for IdP-wide logout in addition to confirming the RP logout. This new parameter deprecates the existing confirm_logout parameter.
- New optional logout_hint parameter in the logout prompt message, of type string, representing the logout_hint RP-initiated logout request parameter.
- New optional ui_locales parameter in the logout prompt, logout end and logout error messages, of type string array, representing the ui_locales RP-initiated logout request parameter.
- New invalid_request error code to indicate an invalid RP-initiated logout request.

SPI

Upgrades the Connect2id server SDK to com.nimbusds:c2id-server-sdk:4.49
- New ExposedInvalidClientException class that extends the common InvalidClientException for representing OAuth 2.0 invalid_client errors, to indicate that the default Connect2id server error_description and error_uri must be overridden with specific values.
  
  The Connect2id has a security policy to log the message of InvalidClientException instances and return a general error_description in the HTTP 401 Unauthorized response that doesn't reveal the exact cause why client authentication failed. The new ExposedInvalidClientException lets client authentication related plugins override this policy and set the error_description and error_uri in the HTTP 401 Unauthorized response. This facility must be used judiciously.
- Connect2id server plugins implementing the PrivateKeyJWTCertificateVerifier SPI can throw the new ExposedInvalidClientException instead of the common InvalidClientException to override the default Connect2id server error_description and error_uri in the resulting HTTP 401 Unauthorized response.
  
  When using the ExposedInvalidClientException to set a custom invalid client error_description care must be taken not to divulge sensitive or more information than necessary.

Resolved issues

Updates the access token (as subject_token) introspection in token exchange grant handling (RFC 8693) to mark tokens which client_id doesn't match the client_id of the requesting OAuth 2.0 client as invalid. In addition, an OP6216 warning will be logged when this condition is encountered (issue server/768).
The logout session web API must not log request query strings at INFO level (issue server/770).

12.14 (2022-06-30)

Summary

Support for OAuth 2.0 Token Exchange (RFC 8693). This is an OAuth 2.0 extension that specifies a generic mechanism for clients to obtain an access token in exchange for another token, which type and encoding can be arbitrary and which issuer can be the same OAuth 2.0 authorisation server or another trusted 3rd party token service. This grant also supports impersonation (act-as) and delegation (on-behalf-of) scenarios. See https://datatracker. ietf.org/doc/html/rfc8693

Web API

/clients
- Supports registration of clients for the OAuth 2.0 token exchange grant ("urn:ietf:params:oauth:grant-type:token-exchange"). The clients can be confidential (with authentication credentials) or public.
/token
- Supports the OAuth 2.0 token exchange grant (RFC 8693), identified by the grant_type "urn:ietf:params:oauth:grant-type:token-exchange". Requires a TokenExchangeGrantHandler SPI plugin.
/monitor/v1/metrics
- Adds new tokenEndpoint.tokenExchange.successfulRequests, tokenEndpoint.tokenExchange.invalidClientErrors, tokenEndpoint.tokenExchange.unauthorizedClientErrors, tokenEndpoint.tokenExchange.invalidGrantErrors and tokenEndpoint.tokenExchange.invalidScopeErrors meters for the OAuth 2.0 token exchange grant.

SPI

Upgrades the Connect2id server SDK to com.nimbusds:c2id-server-sdk:4.48
- TokenExchangeGrantHandler -- New SPI for implementing OAuth 2.0 token exchange (RFC 8693) scenarios. Accepts subject_token and actor_token instances of any token type and issuer. The requested_token_type must be an access token (locally issued). The access token can be of type Bearer, with a client X.509 certificate binding (RFC 8705), or DPoP bound (draft-ietf-oauth-dpop-09). Issue of other types of tokens as well as refresh tokens currently isn't supported.
- ClientCredentialsGrantHandler -- Adds new processGrant method to the SPI to enable handling of token parameters other than scope and provide access to the configured OP / AS issuer URI (necessary for grant handler plugins in multi-tenant Connect2id server deployments). The old processGrant method is deprecated. The new processGrant method has a default implementation that passed the call to the old deprecated method so existing plugins can continue functioning as they are.
- ResourceOwnerPasswordCredentialsGrant -- Adds new processGrant method to the SPI to enable handling of token parameters other than scope and provide access to the configured OP / AS issuer URI (necessary for grant handler plugins in multi-tenant Connect2id server deployments). The old processGrant method is deprecated. The new processGrant method has a default implementation that passed the call to the old deprecated method so existing plugins can continue functioning as they are.
- SelfIssuedJWTGrantHandler -- Adds new processGrant method to the SPI to enable handling of token parameters other than scope and provide access to the configured OP / AS issuer URI (necessary for grant handler plugins in multi-tenant Connect2id server deployments). The old processGrant method is deprecated. The new processGrant method has a default implementation that passed the call to the old deprecated method so existing plugins can continue functioning as they are.
- ThirdPartyJWTGrantHandler -- Adds new processGrant method to the SPI to enable handling of token parameters other than scope and provide access to the configured OP / AS issuer URI (necessary for grant handler plugins in multi-tenant Connect2id server deployments). The old processGrant method is deprecated. The new processGrant method has a default implementation that passed the call to the old deprecated method so existing plugins can continue functioning as they are.
- SelfIssuedSAML2GrantHandler -- Adds new processGrant method to the SPI to enable handling of token parameters other than scope and provide access to the configured OP / AS issuer URI (necessary for grant handler plugins in multi-tenant Connect2id server deployments). The old processGrant method is deprecated. The new processGrant method has a default implementation that passed the call to the old deprecated method so existing plugins can continue functioning as they are.
- ThirdPartySAML2GrantHandler -- Adds new processGrant method to the SPI to enable handling of token parameters other than scope and provide access to the configured OP / AS issuer URI (necessary for grant handler plugins in multi-tenant Connect2id server deployments). The old processGrant method is deprecated. The new processGrant method has a default implementation that passed the call to the old deprecated method so existing plugins can continue functioning as they are.
- Adds a ClaimsSpec field to the GrantAuthorization class. This enables plugins implementing the ClientCredentialsGrantHandler SPI to authorise OAuth 2.0 clients registered for the client_credentials grant to receive an access token for OpenID claims at the UserInfo endpoint. This also enables the existing Connect2id server feature where authorised OpenID claims specified with the access_token: prefix will be fed into the access token.

Resolved issues

Increases the entity size limit of HTTP requests to the client registration endpoint from 20K chars to 250K chars to cater for client registrations with exceptionally large metadata. The entity size limit has been present to prevent DoS attacks in client registration that is open or managed in a way that doesn't enforce a limit on the submitted client metadata (issue server/765).

12.13 (2022-06-20)

Summary

The default Connect2id server codec for self-contained (JWT-encoded) access tokens can now insert selected elements from the client data field and the authorisation data fields as top-level JWT claims. Deployments can use this feature to conform to access token profiles without a custom SelfContainedAccessTokenClaimsCodec plugin.

Configuration

/WEB-INF/authzStore.properties
- authzStore.accessToken.codec.jwt.copyClientData -- New optional configuration property of the default Connect2id server codec for JWT-encoded access tokens. Lists names of members in the client registration's "data" JSON object to copy as top-level JWT claims. An "*" (asterisk) selects all members. If a custom JWT codec (implementing the SelfContainedAccessTokenClaimsCodec SPI) is plugged this setting has no effect.
- authzStore.accessToken.codec.jwt.moveAuthzData -- New optional configuration property of the default Connect2id server codec for JWT-encoded access tokens. Lists the names of members in the authorisation "dat" (data) JSON object to move to top-level JWT claims in access tokens minted by the default self-contained access token encoder. An "*" (asterisk) selects all members. If a custom JWT codec (implementing the SelfContainedAccessTokenClaimsCodec SPI) is plugged this setting has no effect.

SPI

Upgrades the Connect2id server SDK to com.nimbusds:c2id-server-sdk:4.45

12.12 (2022-06-03)

Summary

New plugin interface (Service Provider Interface, or SPI) for accepting qualified X.509 certificates to verify the digital signature in private_key_jwt client authentications.
New plugin interface (SPI) for intercepting client authentication success and failure events at all Connect2id server endpoints where client authentication occurs. Can be used for logging, reporting, audit, debugging and other purposes.
Introduces a secure random 12 byte "client_auth_id" to identify each individual client authentication performed by the Connect2id server in log messages, OAuth 2.0 invalid_client errors and calls to SPIs like the new private key JWT certificate verifier and the client authentication interceptor.
Includes a web-based handler plugin for the OAuth 2.0 client credentials grant, implementing the ClientCredentialsGrantHandler SPI from the Connect2id server SDK. This handler is not compatible with the multi-tenant edition of the Connect2id server. Disabled by default. The default client credentials handler remains the existing local one (com. nimbusds:oauth-client-grant-handler:2.0.2).

Web API

/token
- OAuth 2.0 invalid_client error objects include a "client_auth_id" to identify the client authentication event in server log messages and SPI calls.
/token/introspect
- OAuth 2.0 invalid_client error objects include a "client_auth_id" to identify the client authentication event in server log messages and SPI calls.
/token/revoke
- OAuth 2.0 invalid_client error objects include a "client_auth_id" to identify the client authentication event in server log messages and SPI calls.
/par
- OAuth 2.0 invalid_client error objects include a "client_auth_id" to identify the client authentication event in server log messages and SPI calls.

Configuration

/WEB-INF/clientGrantHandlerWebAPI.properties -- New configuration file for the client credentials grant handler plugin that delegates processing of the grant authorisation to a web-service. The configuration properties can be overridden or set with Java system properties.

SPI

Upgrades the Connect2id server SDK to com.nimbusds:c2id-server-sdk:4.44
- com.nimbusds.openid.connect.provider.spi.clientauth. PrivateKeyJWTCertificateVerifier -- New SPI for verifying an X.509 certificate (x5c) in private_key_jwt} client authentications. This can be used to enable private_key_jwt authentication based on qualified certificates and without a prior client JWK set registration (via the "jwks" or "jwks_uri" client metadata parameters).
  
  The SPI enables implementation of policies where only selected clients are allowed or required to include a certificate for the private_key_jwt, based on the client's registered metadata or other criteria.
  
  A client can place the certificate in the private_key_jwt "x5c" header. Alternatively, the certificate can be put in the "x5c" parameter of a matching public JWK and have the key pre-registered via the "jwks" or "jwks_uri" client metadata parameter.
  
  Implementations must be thread-safe.
- com.nimbusds.openid.connect.provider.spi.clientauth. ClientAuthenticationInterceptor -- New SPI for intercepting successful and failed client authentications at all Connect2id server endpoints where client authentication occurs, such as the token, token introspection, token revocation and pushed authorisation request (PAR) endpoints. Successful client authentications can be subjected to additional checks and rejected with an OAuth 2.0 invalid_client error.
  
  Implementations must be thread-safe. Interceptors that create events should use a separate thread for blocking operations.

Resolved issues

Fixes an HTTP 500 Internal Server Error on a token revocation request with client authentication where the client_id resolves to an invalid client registration (issue server/760).
The message OP0131 ("Couldn't determine Connect2id server local host") should be logged at WARN level, not ERROR (issue server/759).

12.11 (2022-05-22)

Configuration

/WEB-INF/oidcProvider.properties
- op.splashPage -- New configuration property for the splash page to display at the Connect2id server issuer URL (op.issuer).
  
  Supported values:
  - urn:c2id:splash_page:default -- The default splash page, an HTML page showing the Connect2id server version, a list of the available endpoints and links to public online documentation.
  - urn:c2id:splash_page:blank -- A blank page.
  - urn:c2id:splash_page:op_metadata -- Redirects (HTTP 301) to the OpenID provider metadata at /.well-known/openid-configuration
  - https or http URL -- Redirects (HTTP 301) to the specified HTTPS or HTTP URL.

Resolved issues

Fixes a bug that affected the correct handling of the subject session "auth_life" property (for values > 0) in the authorisation session web API, used to determine when the authentication lifetime (in minutes) of a session expires and the subject (end-user) must be re-authenticated in the same session (issue server/756).
Adds custom static error pages for 404, 405 and other HTTP status codes handled by the Servlet container to hide the Servlet container version and other potentially sensitive information (issue server/745).

12.10 (2022-05-03)

Summary

Support for OpenID authentication requests with prompt=create to enable relying parties to instruct the OpenID provider to present the user with a sign-up screen. After the user is successfully registered the flow proceeds as usual. Support for the "create" prompt value is advertised in a new "prompt_values_supported" OpenID provider metadata field. Login handlers integrating with the authorisation session API will receive indication of a prompt=create in a new "create_account" {true|false} parameter of the "auth" message. If the OpenID provider has no requirement or wish to honour prompt=create the login handler can safely ignore the "create_account" flag and render the usual user authentication screen. OpenID prompt=create requests will always trigger an "auth" prompt message in the authorisation session API, similarly to OpenID prompt=select requests.

The Connect2id server will reject OpenID authentication requests with a prompt parameter that contains values other than "create", in accordance with the specification recommendation.

This new prompt "create" value is specified in Initiating User Registration via OpenID Connect - draft 04, see https://openid.net/ specs/openid-connect-prompt-create-1_0.html
Support for minting back-channel logout notification tokens with explicit JWT typing. This is a simple measure to help relying parties simplify the prevention of mix-up of logout token JWTs with other types of JWT without having to examine the JWT claims structure. Enabled by default.

Configuration

/WEB-INF/oidcProvider.properties
- op.logout.backChannel.jwtTypeExplicit -- New configuration property to enable / disable explicit typing of the issued back-channel logout tokens by setting the JWT type ("typ") header to "logout+jwt". Explicit logout token typing is a new recommendation in OpenID Connect Back-Channel Logout 1.0 - draft 07, section 4.1. This is a simple measure to prevent mix-up of logout token JWTs with other types of JWT without having to examine the JWT claims structure. Enabled by default.
  
  See https://openid.net/specs/openid-connect-backchannel-1_0.html
/WEB-INF/infinispan-*-dynamodb.xml
- Removes the default "dynamodb.region" setting of "us-east-1". The purpose of this change is to enable DynamoDB configurations where the AWS region is determined by the default AWS region provider chain, for example by setting the "AWS_REGION" environment variable. The DynamoDB store XML schema is updated to v1.19. See https://docs.aws.amazon.com/ sdk-for-java/v1/developer-guide/java-dg-region-selection.html

Web API

/.well-known/openid-configuration
- prompt_values_supported -- New metadata field defined in Initiating User Registration via OpenID Connect - draft 04. Lists the supported prompt values in OpenID authentication requests. The Connect2id server supports the following prompt values: none, login, consent, select_account and create.
/authz-sessions/rest/v3/
- The authentication prompt (message with type "auth") receives a new "create_account" member of type boolean to indicate an OpenID authentication request with a prompt=create parameter.

Resolved issues

Sourcing of "access_token:*" claims must call the AdvancedClaimsSource SPI instead of the basic ClaimsSource SPI in order to pass optional "claims_data" (issue server/753, authz-store/191).

12.9 (2022-03-23)

Configuration

/WEB-INF/oidcProvider.properties
- op.token.idToken.jwtType -- New configuration property to set the type ("typ") header of issued ID tokens. Explicit JWT typing is a simple measure to prevent mix-up of ID token JWTs with other types of JWT without having to examine the JWT claims structure. Note this is a non-standard feature and may result in rejection of ID tokens by client libraries not able or not configured to handle typing. Typing is disabled by default.
- op.token.userinfo.jwtType -- New configuration property to set the type ("typ") header of issued UserInfo JWTs. Explicit JWT typing is a simple measure to prevent mix-up of UserInfo JWTs with other types of JWT without having to examine the JWT claims structure. Note this is a non-standard feature and may result in rejection of UserInfo JWTs by client libraries not able or not configured to handle typing. Typing is disabled by default.

Web API

/clients/
- Adds support for a new optional "refresh_client_secret" client metadata field of type boolean for use in client update requests. When the "refresh_client_secret" is set to true in a client update request the Connect2id server will refresh the client secret, overriding a disabled op.reg.alwaysRefreshClientSecretOnUpdate configuration setting. When "refresh_client_secret" is set to false or omitted the refresh of the client secret will be determined by the configured op.reg. alwaysRefreshClientSecretOnUpdate setting.
  
  The intent of "refresh_client_secret" is to give registered clients a direct control over how soon or often to refresh their secret. This is a non-standard metadata field.

- com.nimbusds.openid.connect.provider.spi.authz.ValidatorContext -- Adds new getRawRequest method returning the original raw OAuth 2.0 authorisation / OpenID authentication request, as received at the authorisation endpoint and prior to any JAR unwrapping / resolution if JWT-secured.

Resolved issues

Fixes a vulnerability in the Connect2id server banner (splash) page that allowed injection of HTML or JavaScript via an invalid "Issuer" HTTP header. No feasible exploits found, but upgrading is generally recommended. The banner page also receives a Content-Security-Policy to allow only local content (issue server/733).
Fixes a vulnerability at the token endpoint that allowed log injection of CR and LF characters via a client_id prior to client validation. In Connect2id server deployments with a plain text Log4j appender the vulnerability may be exploited to compromise the integrity of the log messages and potentially forge log events. The severity of the vulnerability is low, upgrading is recommended (issue server/734).
Fixes the log label for the token introspection HTTP request logging and the OP6500 internal server error message (issue server/735).
The token and UserInfo endpoints must return an HTTP 400 Bad Request with an invalid_dpop_proof error when receiving a DPoP HTTP request header with a header value that doesn't parse to a signed JWT. Previously the Connect2id server ignored th DPoP header when JWT parsing failed (issue server/736).

Web API

/clients
- Allows registration of a frontchannel_logout_uri with a custom URI scheme. Intended to support front-channel logout notifications to mobile applications (application_type=native) with a custom URI scheme. Previously only https URLs were allowed. The http URL scheme remains disallowed.
/authz-sessions/rest/v3/
- Consent: The API is updated to support opting out of the additional encryption of self-contained (JWT-encoded) access tokens which the Connect2id server will apply when the OpenID relying party is registered for pairwise subjects (with subject_type=pairwise) and the access token subject is also set for a pairwise identifier (with access_token.sub_type=PAIRWISE). The default behaviour of the Connect2id server is to always apply encryption to the JWT-encoded access tokens when the OpenID relying party is registered for pairwise subjects, in order to prevent exposing of information about the underlying subject ID which would happen if the self-contained access token was only signed. When the token subject is made pairwise there is still a theoretical possibility for the OpenID relying party to perform some correlation between the end-users, by observing the variations of the pairwise identifier across multiple token audiences (resource servers), hence the strict default Connect2id policy to also encrypt access tokens with a pairwise subject. To opt out of the default encryption use access_token.encrypt=false in the consent object.
/direct-authz/rest/v2/
- Direct authorisation request: The API is updated to support opting out of the additional encryption of self-contained (JWT-encoded) access tokens which the Connect2id server will apply when the OpenID relying party is registered for pairwise subjects (with subject_type=pairwise) and the access token subject is also set for a pairwise identifier (with access_token.sub_type=PAIRWISE). See the explanation about the related authorisation session web API change. To opt out of the default encryption use access_token.encrypt=false in the consent object.

12.4 (2021-10-27)

Summary

Expands the cryptographic capabilities of the Connect2id server with the ES256K algorithm for JWS, RSA-OAEP-384 and RSA-OAEP-512 for JWE and XC20P (extended nonce ChaCha20 / Poly1305) as JWE encryption method. The ES256K and EdDSA (with 25519 curve) JWS algorithms can now be used to sign ID tokens, UserInfo responses and authorisation responses (JARM). JWT-encoded access tokens can now be signed with the ES256, ES256K, ES384 and ES512 JWS algorithms.

12.3 (2021-09-17)

Summary

Supports issuer URL aliases. An issuer alias URL can be configured to migrate a Connect2id server deployment seamlessly and over time from one issuer identifier URL (op.issuer) to another. Issuer aliases can also be used when an OpenID provider / OAuth 2.0 authorisation server is known by multiple URLs.

The allowed issuer aliases, if any, are configured in a new optional op.issuerAliases.* property.

A Connect2id server endpoint or API will process a request under an issuer alias when the HTTP request header "Issuer" is present and set to a value matching a configured alias. If no "Issuer" header is specified the default issuer configured in op.issuer will be assumed. The default op.issuer will also be assumed when the "Issuer" header is explicitly set to it. If the "Issuer" header is set to an issuer URL that isn't configured the Connect2id server will return an HTTP 400 error with a message.

The "Issuer" header must be set by the reverse HTTP proxy or similar trusted internal infrastructure. It must not be settable by client applications. Connect2id server deployments must scrub the incoming client application HTTP requests from any "Issuer" headers.

Issuer aliases are supported in the regular as well as the multi-tenant Connect2id server edition.

Configuration

/WEB-INF/oidcProvider.properties
- op.issuer.aliases.* -- New optional configuration property for setting one or more issuer alias URLs of the OpenID provider / OAuth 2.0 authorisation server. Can be used to migrate from one issuer URL (op.issuer) to another, or to operate an OpenID provider / OAuth 2.0 authorisation server that is known by multiple URLs. Blank if none.

Web API

The standard OAuth 2.0 / OpenID Connect endpoints and Connect2id server specific web APIs will process a request under a configured issuer alias (op.issuerAliases.*) when the HTTP request includes an "Issuer" header set to the issuer alias URL. The header value must match the configured issuer alias URL exactly. If the "Issuer" header is set to an issuer URL that isn't configured the Connect2id server will return an HTTP 400 "Bad Request" error with an appropriate message.

Summary

Supports issue of access tokens of type DPoP, where the token is bound to a private RSA or EC key generated and held by the OAuth 2.0 client, potentially in secure storage preventing the key's extraction. Use of the DPoP token at a resource server requires proof of possession of the private key, preventing the use of an accidentally or maliciously leaked token by an unauthorised party. The original Bearer tokens in OAuth 2.0 offer no such protection to constrain their use.

DPoP is intended primarily for browser based applications (also commonly called single page applications, or SPAs) where the alternative standard method to constrain a token, by binding it to a client X.509 certificate (RFC 8705), is not suitable, due to the browsers' poor support for dealing with client certificates and mutual TLS in JS application code.

SPAs should use the WebCrypto browser API to generate the necessary private keys (with disabled extraction) for signing the DPoP proofs and actual signing.

The Connect2id server accepts the following JWS algorithms for the signed DPoP proof JWTs: RS256, RS384, RS512, PS256, PS384, PS512, ES256, ES256K, ES384 and ES512.

The Connect2id server will reject DPoP proof JWTs with an "iat" (issued-at time) that is more than 30 seconds behind or ahead of the current system time. Proof JWTs with a repeated "jti" (JWT ID) will also be rejected to prevent replay.

See OAuth 2.0 Demonstrating Proof-of-Possession at the Application Layer (draft-ietf-oauth-dpop-03).
The Connect2id server can now be configured with longer RSA signing and encryption keys, with lengths of 3072 and 4096 bits. The 2048 RSA key length remains the recommended for now and also the default for in provided jwkset-gen.jar tool for generating server JWK sets (the latest tool version is 1.22).

Summary

Uniform pairwise subject IDs

Adds support for issuing pairwise subject identifiers with a uniform string length which is not affected by the length of the local (system) subject identifiers. This measure is intended to prevent leaking information about the length of the local subject identifiers. Uniformity is configured with a new "op.pairwiseSubjects.padLocalSubjectsToLength" property. It specifies a length to which a local subject identifier will be padded before input to the pairwise codec (SIV mode deterministic AES encryption). For uniform pairwise subject lengths the property should be set to the maximum expected length of the local subjects. Subject IDs longer than the configured length will result in a pairwise encoding that is proportionally longer.

Setting the property to -1 (negative integer) disables padding, which is the behaviour of the pairwise codec in previous Connect2id server versions.

Example pairwise IDs for local subjects "alice", "bob" and "claire" with no padding:

myzM-ARj7vYBH9NOIog9Sf5xklhU_rkLenu8mOtfLv6L Q20o2EYNsamhlOh2RbteNp7Te7AilmMPVk3cyhmCBA rNW4ByxEQd06rNCLLMvH2-d1WRumrJcSrmDGA6FlvtxeGw

With padding up to 10 characters:

pxXoRPqPpLy3fBbLNV22KRCghztrFMtGV3AxDnQH_erfB4dwZ_0 s10h_EEMtYHaNSZuMBznfvupKqC2mznkIGnmxRevffJGo4ybRrM uLfwVCpRUu1ltEeXqRt_Yik7SN5-yKabYwXan-xYCwgJlDZubSA

Important: Changing the padding length will reset all previously issued pairwise subject identifiers!

Configuration choices for "op.pairwiseSubjects.padLocalSubjectsToLength":
- Configure a length to issue uniform pairwise subject IDs: if pairwise subjects have never been issued or to benefit from the new improved security. In the latter case don't forget to notify the relying parties of the reset!
- No padding: to ensure backward compatibility if pairwise subjects have already been issued and a reset is not desirable. Also, if the local subjects have a uniform length, for example when based on a GUUID which has a constant length of 37 characters.
OpenID provider managed sector IDs

Connect2id server deployments that need to issue ID tokens and UserInfo responses with pairwise (pseudonymous) subject (end-user) identifiers to two or more OpenID relying parties under single administrative control can now do so without requiring the relying parties to host a JSON document for the "sector_identifier_uri" client registration parameter. A single OpenID relying party can also choose to register a "sector_identifier_uri" to ensure the pairwise "sub" values in the received ID tokens and UserInfo responses remain consistent if its registered redirection URI changes in future. See OpenID Connect Dynamic Client Registration 1.0 incorporating errata set 1, section 5, for an explanation of the "sector_identifier_uri" parameter and its validation.

For such relying parties an OpenID provider can now manage the sector IDs internally, in some a database or portal, by assigning unique sector ID URNs to them prior to registration. Those URNs will not get resolved and validated in the same way a standard https URL in the "sector_identifier_uri" parameter gets, by downloading a JSON document from the URL. Instead, the URN will be used to provide the sector ID directly. The expected URN format is urn:c2id:sector_id:<id> where <id> represents the sector ID assigned to a relying party or group of relying parties.

To use this feature the new "op.reg.enableProviderManagedSectorIDs" configuration property must be turned on. The client registration POST or PUT request must be authorised with a master API token or one-time registration token with a "client-reg:set-sector-id-urn" scope value. Unauthorised requests (if open registration is allowed) cannot use sector ID URNs.
Access tokens with pairwise subjects

The Connect2id server can now optionally issue access tokens with a subject (end-user) identifier made pairwise for the token's intended audience (resource server).

Use tokens with a pairwise subject:
- To keep the local (system) end-user ID confidential from the resource servers, as privacy measure, especially if the subject identifier represents or contains personal information, such as the user's email address or social security number.
- To minimise the possibility for resource servers to link or correlate the identity of users. The pairwise identifier for a given subject (end-user) in an access token will be different, unique and not-reversible for each resource server (token audience).
The Connect2id server computes the pairwise identifier for an access token by applying strong deterministic SIV AES based encryption over the concatenation of the token audience and the local subject identifier.

pairwise_sub = SIVAES(aud|local_sub)

The algorithm is identical to the one the Connect2id server uses to compute pairwise subject identifiers for ID tokens and UserInfo responses and uses the same "subject-encrypt" AES key from the configured server JWK set.

JWT-encoded as well identifier-based access tokens are supported.

Note, to issue access tokens with a pairwise subject the token authorisation must specify an explicit token audience for the intended resource server(s). If the audience is a list of multiple values the first one will be used to compute the pairwise subject. This enables the issue of tokens with a pairwise subject where there are multiple audiences as aliases specified, for example the resource indicator, e.g. "https://api.example.com", as primary audience and the resource server client ID, e.g. "Zoo0rah0", to enable token introspection at the Connect2id server endpoint with an audience restriction check on the client_id.

Also note that access tokens with a pairwise subject that grant release of OpenID claims at the UserInfo endpoint, as only or additional scope, need not specify the UserInfo endpoint or the OpenID provider issuer URL as audience.

If required for audit purposes a pairwise subject identifier can be decrypted (reversed) with the Connect2id server's configured "subject-encrypt" JSON Web Key (JWK). See https://bitbucket.org/connect2id/pairwise-subject-codec/ .
Allows issue of the access and refresh tokens without a scope, to ease handling of OAuth 2.0 Rich Authorisation Requests (RAR). See https://datatracker.ietf.org/doc/html/draft-ietf-oauth-rar-05

Configuration

/WEB-INF/oidcProvider.properties
- op.pairwiseSubjects.padLocalSubjectsToLength -- New configuration property to enable output of pairwise subject identifiers with a uniform string length which is not affected by the length of the local (system) subject identifier. Intended to prevent leaking information about the length of the local subject identifiers. Uniformity is achieved by padding local subject identifiers up to the specified length, which should be the maximum expected length of the local subjects. Subjects longer than the configured length will result in a pairwise encoding that is proportionally longer.
  
  -1 (negative integer) disables padding.
  
  Important note: Changing the padding length will reset all previously issued pairwise subject identifiers!
- op.reg.enableProviderManagedSectorIDs -- New configuration property to enable registration of OpenID provider managed sector identifiers for the computation of pairwise subject (end-user) identifiers. A managed sector ID can be registered with the "sector_identifier_uri" set to a URN with the format urn:c2id:sector_id:<id>. The registration requires a master API token or a one-time registration token with a "client-reg:set-sector-id-urn" scope value. The default value is false (disabled).
/WEB-INF/infinispan-*-{mysql|postgres95|sqlserver|h2}.xml
- Adds new "ats" (access token subject type) columns to the "id_access_tokens" and "long_lived_authorizations" tables. In existing Connect2id server deployments with an SQL RDBMS the server will automatically add the new columns (with an appropriate default value) on startup.
/WEB-INF/infinispan-*-ldap.xml
- Adds new "authzAccessTokenSubjectType" attribute to the "oauth2IdAccessToken" and "oauth2Authz" object classes. Connect2id server deployments with an LDAP v3 backend database (such as OpenLDAP or OpenDJ) need to update the LDAP schema manually to version 1.17 see https://bitbucket.org/connect2id/server-ldap-schemas/src/1.17/ , the OpenLDAP schema diff https://bitbucket.org/connect2id/server-ldap-schemas/diff/ src/main/resources/oidc-authz-schema-openldap.ldif?at=1.17 &diff1=4c78a00734bfeb9abdd4c9dec76d9fbc51216faa &diff2=cdfdb912753b17a0fed7c08aa500be53cb767cd7 and the OpenDJ schema diff https://bitbucket.org/connect2id/server-ldap-schemas/diff/ src/main/resources/oidc-authz-schema-opendj.ldif?at=1.17 &diff1=4c78a00734bfeb9abdd4c9dec76d9fbc51216faa &diff2=cdfdb912753b17a0fed7c08aa500be53cb767cd7

Web API

/clients
- Adds support for registering OpenID relying parties for pairwise subject identifiers where the "sector_identifier_uri" parameter is a URN for a sector ID that is managed by the OpenID provider. The expected URN format is urn:c2id:sector_id:<id>. The OpenID provider must manage the assignment of the URN sector IDs to relying parties prior to registration and ensure that the ID stays unique for a given OpenID relying party, unless the sector ID is allowed to be shared by two more relying parties, typically when those are under single administrative control. To register URN sector IDs the "op.reg.enableProviderManagedSectorIDs" configuration property must be enabled. The registration must be authorised with a master API token or a one-time registration token with a "client-reg:set-sector-id-urn" scope value.
- Will return an "invalid_client_metadata" OAuth 2.0 error with a suitable description message when the client registration request is not authorised for a "preferred_client_id", "preferred_client_secret" or custom "data" parameter. Previously those parameters will be silently scrubbed from the registration request if not authorised (by means of the master API token or a specific one-time registration token).
/token
- Supports issue of access tokens with a pairwise subject identifier encoded for the token audience as sector identifier. If the token has multiple audiences the first audience value in the list is taken as the sector identifier. Access tokens for releasing OpenID claims at the UserInfo endpoint that have pairwise subject need not include the UserInfo endpoint or the OpenID issuer URL in its audience.
/token/introspect
- Supports introspection of access tokens with a pairwise subject identifier. The standard "sub" (subject) field will be set to the pairwise identifier.
/token/revoke
- Supports revocation of access tokens with a pairwise subject identifier.
/userinfo
- Supports access tokens with a pairwise subject identifier. Note, access tokens for OpenID claims that have a pairwise subject identifier need not include the UserInfo endpoint or the OpenID issuer URL in its audience.
/authz-sessions/rest/v3/
- Consent prompt: Adds new optional "sub_type" member of type string with values "PUBLIC" (default) or "PAIRWISE" to the "access_token" JSON object. When set to "PAIRWISE" the Connect2id server will issue an access token with a pairwise subject identifier. This requires the consent to specify a token "audience" (if multiple audience values are set the first in the list will used to compute the pairwise identifier).
- Consent: The consent can now specify an empty or null "scope" to enable handling of Rich Authorisation Requests (RAR). In this case the issued access and refresh tokens will not contain a scope. Previously a consent PUT with an empty scope would cause an "access_denied" OAuth error to be returned to the client. Integrations must now explicitly trigger an "access_denied" OAuth 2.0 error via the authorisation session web API.
/direct-authz/rest/v2/
- Direct authorisation request: Adds new optional "sub_type" member of type string with values "PUBLIC" (default) or "PAIRWISE" to the "access_token" JSON object. When set to "PAIRWISE" the Connect2id server will issue an access token with a pairwise subject identifier. This requires the request to specify a token "audience" (if multiple audience values are set the first in the list will used to compute the pairwise identifier).
/authz-store/rest/v3/
- OAuth 2.0 / OpenID Connect authorisation object: Adds new optional "ats" (access token subject type) member of type string with values "PUBLIC" (default) or "PAIRWISE".

Summary

Adds a set of new Connect2id server configuration properties for setting up OAuth 2.0 servers conforming to version 2021-03-12 of the FAPI 1.0 Advanced security profile. See Financial-grade API Security Profile 1.0 - Part 2: Advanced (2021-03-12).
Adds configuration properties for causing selected OAuth 2.0 authorisation request parameters, including custom parameters, to appear in the authentication or consent prompt in the authorisation web API. Intended to save HTTP GET calls to the authorisation session resource when access to those parameters is needed.

Configuration

/WEB-INF/oidProvider.properties
- op.authz.alwaysRequireRedirectURI -- New configuration property to specify whether the redirect_uri parameter is required for all authorisation requests. The default value is false (required only for OpenID authentication requests).
- op.authz.alwaysRequireSignedRequestJWT -- New configuration property to specify whether a JWS signed request JWT passed inline via "request" or by URL reference via "request_uri" will be required for all authorisation requests. The default value is false (not required unless the client is explicitly registered for it).
- op.authz.requireRequestJWTNotBefore -- New configuration property to specify whether received request object JWTs must include a not before (nbf) claim. The default value is false.
- op.authz.maxLifetimeRequestJWTExpiration -- New configuration property to specify the maximum accepted lifetime in seconds of an expiration (exp) claim in request JWTs. The lifetime is computed from the not before (nbf) claim if present, otherwise from the current time. The default value is -1 (not specified).
- op.authz.maxAgeRequestJWTNotBefore -- New configuration property to specify the maximum accepted age in seconds of a not before (nbf) claim in request JWTs. The default value is -1 (not specified).

Configuration

/WEB-INF/infinispan-stateless-redis-dynamodb.xml -- New Infinispan configuration file for storing short-lived and cached data in Redis, and long-lived data in DynamoDB. Long-lived data in DynamoDB can be transparently cached by turning the optional Amazon DynamoDB Accelerator (DAX) for the DynamoDB tables.

This Infinispan configuration is suitable for single-region deployments in AWS as well as multi-region deployments where only replication of long-lived data in DynamoDB via the "global-tables" feature is required.

This Infinispan configuration is an alternative to the existing available "infinispan-stateless-dynamodb.xml" configuration where the long-lived as well as the short-lived and cached data is stored in DynamoDB. Both types of data in that configuration can be replicated via the "global-tables" feature.
/WEB-INF/cors.properties
- cors.enable -- New configuration property for disabling the CORS Filter. If false the CORS Filter is disabled and will pass all HTTP request and response headers unmodified. The CORS Filter can be disabled if the Connect2id server is provisioned with a reverse proxy handling CORS. The default value is true enabling the CORS Filter to process cross-domain requests according to its configuration.

Disables access to external entities in XML parsing in the OAuth 2.0 SDK SAML2AssertionValidator, closing a potential vulnerability when processing OAuth 2.0 grants of type SAML 2.0 bearer assertion (urn:ietf:params:oauth:grant-type:saml2-bearer). The exchange of SAML 2.0 bearer assertions for OAuth access tokens is not enabled by the Connect2id out of the box and requires a plugin. Deployments that have implemented such a plugin for the SelfIssuedSAML2GrantHandler or ThirdPartySAML2GrantHandler should upgrade (issue oidc-sdk/356).

11.1 (2021-02-17)

Summary

Support for AWS DynamoDB in the multi-tenant edition of the Connect2id server. Persisted tenant specific objects are isolated in their DynamoDB tables by means of a range (sort) key named "tid".
Reduces the footprint of AWS related dependencies by switching from the AWS Java SDK bundle to smaller service specific dependencies. The size of the final WAR file is reduced from 244 megabytes to 68 megabytes. If an SPI implementation (custom plugin) requires an AWS dependency previously available through the AWS Java SDK bundle it now needs to be explicitly included as a dependency.

11.0 (2021-02-09)

Summary

Supports OAuth 2.0 client authentication with a client X.509 certificate issued by a trusted Certificate Authority (CA), as specified in OAuth 2.0 Mutual-TLS Client Authentication and Certificate-Bound Access Tokens (RFC 8705), section 2.2.

When registering a client for the "tls_client_auth" method the "tls_client_auth_subject_dn" metadata parameter must be set to the expected subject distinguished name (DN) of the client certificate. Other client metadata parameters defined in RFC 8705 for identifying the certificate subject are not presently supported.

The client certificate is to be validated at a terminating TLS reverse proxy which must pass a successfully validated certificate to the Connect2id server in the HTTP security header set by the existing "op.tls.clientX509CertHeader" configuration property.

Note, due to limitations of the commonly available TLS termination software, configuring simultaneous validation of CA-issued client certificates as well as acceptance of self-signed client certificates is normally not possible. Because of that a Connect2id server deployment can be configured to support either "tls_client_auth" or "self_signed_tls_client_auth" from RFC 8705, but not both.
Supports the JWT-secured authorisation response mode (JARM). An OAuth 2.0 client can utilise JARM to receive signed and optionally encrypted authorisation responses. All standard response modes in JARM are supported: "query.jwt", "fragment.jwt", "form_post.jwt" and the "jwt" shorthand.

A client can request an RS256 signed authorisation response by setting the optional "response_mode" authorisation request parameter to "jwt" or a more specific value, such as "query.jwt". If the client is registered with an "authorization_signed_response_alg" metadata parameter all authorisation responses will be signed with the specified JWS algorithm, even if there is no explicit request for JARM in the "response_mode" authorisation request parameter. If the client is also registered with the "authorization_encrypted_response_alg" and "authorization_encrypted_response_enc" metadata parameters the signed authorisation response will be additionally encrypted.

See Financial-grade API: JWT Secured Authorization Response Mode for OAuth 2.0 (JARM), draft 02 from 2018-10-17.
Adds a codec plugin interface (SPI) for persisting client secrets in a encrypted, hashed or otherwise encoded form. The codec interface also enables import of OAuth 2.0 client registrations via the custom "preferred_client_secret" metadata field where the secret is passed in a hashed form, for example using the BCrypt, SCrypt, Argon2 or another hash algorithm.
Supports seamless "client_secret" rollover. After an update of a client's secret via the client registration endpoint the previous secret will remain valid for client authentication purposes for a period of 30 minutes. HMAC-secured ID tokens hints ("id_token_hint" with JWS HS256, HS384 or HS512) will also be checked against the previous replaced "client_secret".
Upgrades the OAuth 2.0 / OpenID Connect SDK to major release 9.x which in turn upgrades to Nimbus JOSE+JWT 9.x. The objective of the Nimbus JOSE+JWT 9.0 release was to shade the JSON Smart dependency and make it optional. Plugged SPI implementations that rely on Nimbus JOSE+JWT 8.x and earlier interfaces and classes may be affected and should be recompiled / rebuilt and if necessary, modified.
Upgrades the schemas of backend RDBMS and LDAPv3 stores to support the client metadata fields required for "tls_client_auth" and JARM. See the configuration section below for more information.

Configuration

/WEB-INF/oidProvider.properties
- op.authz.responseModes -- Adds support for the "query.jwt", "fragment.jwt", "form_post.jwt" and "jwt" (shorthand) response modes from JARM.
- op.authz.responseJWSAlgs -- New configuration property, sets the accepted JWS algorithms for signed OAuth 2.0 authorisation responses (JARM). Supported JWS algorithms: HS256, HS384, HS512, RS256, RS384, RS512, PS256, PS384, PS512, ES256, ES384 and ES512.
- op.authz.responseJWEAlgs -- New configuration property, sets the accepted JWE algorithms for encrypted OAuth 2.0 authorisation responses (JARM). Note, encryption is always applied after signing. Supported JWE algorithms: RSA-OAEP-256, RSA-OAEP (use no longer recommended), RSA1_5 (use no longer recommended), ECDH-ES, ECDH-ES+A128KW, ECDH-ES+A192KW, ECDH-ES+A256KW and dir.
- op.authz.responseJWEEncs -- New configuration property, sets the accepted JWE content encryption methods for encrypted OAuth 2.0 authorisation responses (JARM). Supported JWE methods: A128CBC-HS256, A192CBC-HS384, A256CBC-HS512, A128GCM, A192GCM and A256GCM
- op.token.authMethods -- Adds support for "tls_client_auth", PKI client authentication where the client must include a CA-issued client X.509 certificate in requests. Note, the "tls_client_auth" and "self_signed_tls_client_auth" methods cannot be enabled simultaneously.
- op.tls.clientX509CertHeader -- The existing Connect2id server configuration property for specifying an HTTP header name for receiving validated client X.509 certificates from the TLS proxy will also apply to the new "tls_client_auth" method. The configuration property was originally introduced in Connect2id server 6.12 to facilitate the "self_signed_tls_client_auth" method.
/WEB-INF/infinispan-*-{mysql|postgres95|sqlserver|h2}.xml
- Adds new "tls_client_auth_subject_dn", "tls_client_auth_san_dns", "tls_client_auth_san_uri", "tls_client_auth_san_ip", "tls_client_auth_san_email", "authorization_signed_response_alg", "authorization_encrypted_response_alg" and "authorization_encrypted_response_enc" columns to the "clients" table. In existing Connect2id server deployments with an SQL RDBMS the server will automatically add the new columns (with an appropriate default value) on startup.
/WEB-INF/infinispan-*-ldap.xml
- Adds new "oauthTLSClientAuthSubjectDN", "oauthTLSClientAuthSANDNS", "oauthTLSClientAuthSANURI", "oauthTLSClientAuthSANIP", "oauthTLSClientAuthSANEmail", "oauthAuthorizationResponseJWSAlg", "oauthAuthorizationResponseJWEAlg" and "oauthAuthorizationResponseJWEEnc" attributes to the "oauthClientMetadata" object class. Connect2id server deployments with an LDAP v3 backend database (such as OpenLDAP or OpenDJ) need to update the LDAP schema manually to version 1.15 see https://bitbucket.org/connect2id/server-ldap-schemas/src/1.15/ , the OpenLDAP schema diff https://bitbucket.org/connect2id/server-ldap-schemas/diff/ src/main/resources/oidc-client-schema-openldap.ldif?at=1.15 &diff1=c8ba0c6a092c409e43b9efe7360cd76a460a2b95 &diff2=cb3676cefe8bbccbcdb4352cc707a53ef53ae28a and the OpenDJ schema diff https://bitbucket.org/connect2id/server-ldap-schemas/diff/ src/main/resources/oidc-client-schema-opendj.ldif?at=1.15 &diff1=c8ba0c6a092c409e43b9efe7360cd76a460a2b95 &diff2=cb3676cefe8bbccbcdb4352cc707a53ef53ae28a
/WEB-INF/oidcClientInfoMap.json -- File removed, switched to programmatic configuration.

Web API

/.well-known/openid-configuration, /.well-known/oauth-authorization-server
- response_modes_supported -- Will include the supported OAuth 2.0 response modes for JARM if enabled -- "query.jwt", "fragment.jwt", "form_post.jwt" and "jwt".
- authorization_signing_alg_values_supported -- New optional JSON array listing the supported JWS algorithms for signed OAuth 2.0 authorisation responses (JARM).
- authorization_encryption_alg_values_supported -- New optional JSON array listing the supported JWE algorithms for encrypted OAuth 2.0 authorisation responses (JARM).
- authorization_encryption_enc_values_supported -- New optional JSON array listing the supported JWE content encryption methods for encrypted OAuth 2.0 authorisation responses (JARM).
/clients
- Supports the "authorization_signed_response_alg", "authorization_encrypted_response_alg" and "authorization_encrypted_response_enc" client metadata parameters from JARM.
- Supports registration of clients for PKI mutual-TLS client authentication ("tls_client_auth") with the "tls_client_auth_subject_dn" metadata parameter used to set the expected subject DN in the client's certificate.
- Updating a "client_secret" will cause the previous value to remain valid for client authentication purposes for another 30 minutes, to facilitate seamless rollover.

SPI

Upgrades the Connect2id server SDK to com.nimbusds:c2id-server-sdk:4.27.1
com.nimbusds.openid.connect.provider.spi.secrets.ClientSecretStoreCodec -- New Service Provider Interface (SPI) for encoding OAuth client secrets before persisting them to storage. Can be used to symmetrically encrypt (e.g. with AES) or to hash secrets (e.g. with SCrypt, BCrypt, Argon2) before committing them to storage. Note, OAuth clients registered for "client_secret_jwt" authentication where the secret must be available in plaintext to perform HMAC must not be hashed. This also applies to secrets which may otherwise require the plain secret to be available for decoding, for example to facilitate symmetric encryption of ID tokens or UserInfo.

The supplied SecretCodecContext provides access to the Connect2id server JWK set to retrieve any configured symmetric keys for the client secret encryption, as well as the client metadata to determine the registered client authentication method.

Implementations must be thread-safe.

Resolved issues

The Connect2id server should also include the previous replaced client_secret when validating an id_token_hint secured with JWS HS256, HS384 and HS512 (issue server/12).
Adds missing persistence for the "software_version" client metadata field in LDAP stores (iss #623).
The Connect2id server must not redirect back to an OAuth 2.0 client with an otherwise redirectable authorisation error if no "redirect_uri" was set in the original plain OAuth 2.0 authorisation request and the client has more than one "redirect_uri" registered (issue server/630).
Revises Connect2id server error reporting on invalid a "request_uri" and "request" JWT in a authorisation request. Errors due to the JWT claims including a "sub" (subject) claim that equals the "client_id" will be reported to the client with an "invalid_request" code, instead of resulting in a non-redirecting error. Errors due to a JWT that cannot be decrypted will also be reported to the client with an "invalid_request_object" code, instead of resulting in a non-redirecting error (issue server/631).
Caches single-tenant static OP / AS metadata to increase performance (iss server/627).

10.4 (2020-12-21)

Summary

Adds a plugin for verifying software statements in OAuth 2.0 client registration requests.
Introducing configurable caching for selected metrics which report Connect2id server object count in order to conserve database query resources.
Upgrades OpenID Connect Federation 1.0 support to draft 14.

Configuration

/WEB-INF/monitor.properties
- monitor.entryCountCacheTimeout -- New configuration property, specifies a timeout for caching entry count results, in seconds. Zero disables caching, negative disables readings, causing the gauge to always return -1. The default timeout value is 1800 seconds (30 minutes).
  
  Gauges with entry count caching:
  - authzSessionStore.numSessions
  - sessionStore.numSessions
  - clientStore.numRegistrations
  - clientStore.numCachedRemoteJWKSets
  - clientStore.numCachedRemoteRequestObjects
  - authzStore.numAuthzCodes
  - authzStore.numIdAccessTokens
  - authzStore.numLongLivedAuthorizations
  - authzStore.numRevocationJournalEntries

Web API

/federation/clients
- Upgrades explicit federation Relying Party (RP) registration to draft 14. The trust_anchor_id will now be returned as top-level entity statement claim about the registered RP, instead of as RP metadata parameter.
/monitor/v1/metrics
- Introduces caching to the following gauges which report the number of persisted or cached Connect2id server objects for a given type. Intended to conserve database resources when querying the object count is expensive, for example in MySQL tables with millions of rows. The caching and timeout is controlled by the new monitor.entryCountCacheTimeout configuration property.
  - authzSessionStore.numSessions
  - sessionStore.numSessions
  - clientStore.numRegistrations
  - clientStore.numCachedRemoteJWKSets
  - clientStore.numCachedRemoteRequestObjects
  - authzStore.numAuthzCodes
  - authzStore.numIdAccessTokens
  - authzStore.numLongLivedAuthorizations
  - authzStore.numRevocationJournalEntries

SPI

com.nimbusds.openid.connect.provider.spi.grants.ClientCredentialsGrantHandler
- Upgrades the included OAuth 2.0 client credentials grant handler plugin, see https://bitbucket.org/connect2id/client-credentials-grant-handler .
  - New op.grantHandler.clientCredentials.simpleHandler.accessToken.includeClientMetadataFields configuration property to specify names of client metadata fields to include in the optional access token data field, empty set if none. To specify a member within a field that is a JSON object member use dot (.) notation.
  - The op.grantHandler.clientCredentials.simpleHandler.enable configuration property receives a default value false (disabled).
  - Lets op.grantHandler.clientCredentials.simpleHandler.accessToken.audienceList also apply to identifier-based access tokens.
  - Makes the /WEB-INF/clientGrantHandler.properties configuration file optional.
com.nimbusds.openid.connect.provider.spi.reg.RegistrationInterceptor
- Allows more than one RegistrationInterceptor SPI implementation to be present, but only at most one can be enabled.
- New plugin for verifying optional software statements included in OAuth 2.0 client registration requests. Also supports registration requests encoded into a signed JWT and submitted over mutual TLS with a client X.509 certificate, to conform with Open Banking and other profiles. See https://bitbucket.org/connect2id/software-statement-verifier .

Resolved issues

Submitted client X.509 certificate must be supplied to the RegistrationInterceptor SPI (issue server/618).
Client certificate extraction log messages OP6020 and OP6021 must be assigned to the appropriate Connect2id server endpoint (issue server/617).
Improves exception messaging and logging when parsing corrupted string array fields from SQL records (issue server/470).

- op.authz.allowedPKCE -- New optional configuration property specifying the allowed PKCE (RFC 7636) code challenge methods which OAuth 2.0 clients may use at the authorisation endpoint, as comma and / or space separated list. The default allowed code challenge methods are "plain" and "S256" (all RFC 7636 methods).
  
  Authorisation requests which use a code challenge method that isn't allowed by the configuration will be rejected with an invalid_request error.
  
  The allowed code challenge methods will be advertised in the OpenID provider / OAuth 2.0 authorisation server "code_challenge_methods_supported" metadata field.

10.2 (2020-11-13)

Summary

Includes the Connect2id server issuer URL as "iss" parameter in authorisation responses. Intended for OAuth 2.0 clients using more than one authorisation server to prevent a class of attacks called "mix-up" attacks. Clients interacting with a single OAuth 2.0 server and OpenID relying parties which receive an ID token (and accordingly validate the "iss" claim) are not affected. See OAuth 2.0 Authorization Server Issuer Identifier in Authorization Response (draft-meyerzuselhausen-oauth-iss-auth-resp-01) for further details.
Tightens the URI scheme policy for OAuth 2.0 client metadata to prevent potential attacks using malicious "javascript", "data" and "vbscript" schemes in old and insufficiently protected web browsers. Deployments which utilise open client registration are advised to upgrade. See the article at https://security.lauritz-holtmann.de/post/sso-security-redirect-uri/ for further details.
Updates the logout web API to facilitate post-logout redirections in cases when the end-user session has expired.

Configuration

/WEB-INF/oidcProvider.properties
- op.policy, op.tos, op.serviceDocs -- If the optional policy, terms of service and service documentation links are specified by absolute URL, the scheme must be either "https" or "http".

Web API

/.well-known/openid-configuration, /.well-known/oauth-authorization-server
- Adds the "authorization_response_iss_parameter_supported" metadata parameter (the value is set to true), as specified in OAuth 2.0 Authorization Server Issuer Identifier in Authorization Response (draft-meyerzuselhausen-oauth-iss-auth-resp-01).
/authz-sessions/rest/v3/
- Includes an "iss" (issuer) parameter in OAuth 2.0 authorisation success and error responses, as specified in OAuth 2.0 Authorization Server Issuer Identifier in Authorization Response (draft-meyerzuselhausen-oauth-iss-auth-resp-01). Intended for OAuth 2.0 clients using more than one authorisation server to prevent a class of attacks called "mix-up" attacks. Clients interacting with a single OAuth 2.0 server and OpenID relying parties which receive an ID token (and accordingly validate the "iss" claim) are not affected.
/clients
- Registration of OAuth 2.0 clients and OpenID relying parties with "redirect_uris" or "post_logout_redirect_uris" containing the custom URI schemes "javascript", "data" and "vbscript" is prohibited for security reasons. Native applications can continue registering redirection URIs with custom URI schemes which don't match the prohibited.
- Registration of OAuth 2.0 clients with "client_uri", "policy_uri" or "tos_uri" with URI schemes other than "https" and "http" is prohibited for security reasons.
- Registration of OpenID relying parties will no longer permit custom URI schemes for "frontchannel_logout_uri" and "backchannel_logout_uri". The only permitted URI scheme is "https".
/logout-sessions/rest/v1/
- Updates the logout session web API to not return an "invalid_session" error when the submitted end-user session SID (typically stored in a browser cookie at the IdP domain) is invalid or expired. OpenID relying parties (RP) making a logout request with a valid "post_logout_redirect_uri" will thus be able to complete the redirection, regardless of the end-user session state at the IdP.
  
  Following this change "invalid_session" errors will no longer be returned by the logout session web API.

Resolved issues

Prohibits registration of OAuth 2.0 clients and OpenID relying parties with "redirect_uris" or "post_logout_redirect_uris" with the custom URI schemes "javascript", "data" and "vbscript" for security reasons. Also requires browser rendered URIs derived from client and server metadata, such as "client_uri", "policy_uri" and "tos_uri" to have an "https" or "http" URI. See https://security.lauritz-holtmann.de/post/sso-security-redirect-uri/ for more information (issue server/611).
Prohibits registration of OpenID relying parties with custom "frontchannel_logout_uri" and "frontchannel_logout_uri" URI schemes, thus making "https" the only allowed URI scheme (issue server/612).
Improves INFO logging at the logout session endpoint (issue server/610).

10.1 (2020-10-29)

Summary

Adds support for OpenID Connect Federation 1.0 (draft 12) automatic clients. Automatic clients don't register explicitly with the Connect2id server, instead they proceed directly to the authorisation endpoint, where they submit a signed request object (JWT) containing additional federation- specific claims, thus letting the request object also serve as an implicit authenticated registration request. The Connect2id server will perform the regular federation trust chain resolution and retrieve the client's metadata from its federation entity statement published at a well-known endpoint. The client registration will expire according to a configured policy - a set lifetime or the trust chain lifetime.

See https://openid.net/specs/openid-connect-federation-1_0-12.html.
Updates OpenID Connect for Identity Assurance 1.0 (draft 11) support to accept "claims" authentication request parameters where the "verified_claims" element is a JSON array. This is intended to enable requests for claims sets with different verification requirements (e.g. different trust frameworks). Previously such requests will result in a invalid_request error at the authorisation endpoint.

Example "claims" request for two verifications, using the "eidas_ial_substantial" and the "de_aml" trust frameworks:
```
{
"userinfo": {
  "verified_claims": [
    {
      "verification": {
        "trust_framework": {
          "value": "eidas_ial_substantial"
        }
      },
      "claims": {
        "given_name": null,
        "family_name": null
      }
    },
    {
      "verification": {
        "trust_framework": {
          "value": "de_aml"
        }
      },
      "claims": {
        "birthdate": null
      }
    }
  ]
}
}
```
The consent prompt in the authorisation session API will list the requested verified claims across all elements in the "verified_claims" JSON array.

Note that "claims" -> "verification" will only present the first requested "verification" element if multiple are found. Use the "claims" -> "raw_request" to obtain all verifications. A future version of the Connect2id server will update the consent prompt to simplify handling of verified claims requests with multiple verifications.

See https://openid.net/specs/openid-connect-4-identity-assurance-1_0-11.html, section 6.3.3.
Connect2id server deployments with an AWS DynamoDB backend can be configured to include a SHA-256 based message authentication code (HMAC) in each stored item to guarantee its integrity and authenticity while stored in the database.

Configuration

/WEB-INF/oidcProvider.properties
- op.federation.clientRegistrationTypes -- The configuration property for the supported OpenID Connect Federation 1.0 client registration types now allows for automatic as well as explicit registration.
- op.federation.autoClientAuthMethods.ar -- New configuration property specifying the supported methods for authenticating implicit registration requests of OpenID Connect Federation 1.0 automatic clients at the OAuth 2.0 authorisation endpoint. The only currently supported method is "request_object".
- op.federation.autoClientLifetime -- New configuration property for the lifetime of registered OpenID Connect Federation 1.0 automatic clients, in seconds. If zero or negative the lifetime will be determined by the trust chain expiration time. When explicitly set must not be shorter than 5 minutes (300 seconds) to allow sufficient time for the completion of a single OAuth 2.0 flow with an authorisation, token and UserInfo request by the registered relying party. The default lifetime is one hour (3600 seconds).
/WEB-INF/infinispan-*-dynamodb.xml
- Updates the DynamoDB store schema to v1.8 and adds the option to secure the integrity and authenticity of the stored DynamoDB items with a SHA-256 based Message Authentication Code (HMAC), appended to each item in a "_hmac#256" binary attribute. If a retrieved DynamoDB item is missing the "_hmac#256" attribute or its verification fails the Connect2id server will produce an HTTP 500 Internal Server Error, log the error with a "DS0131" code and increment the ".dynamoDB.invalidItemHmacCounter" metric.
  
  To enable this HMAC protection the Connect2id server must be configured with a secret 256 bit key (as BASE-64 encoded string) in the "dynamoDB.hmacSHA256Key" Java system property.
  
  The HMAC protection must be enabled for newly provisioned or empty DynamoDB tables. Enabling the protection for DynamoDB tables with prior existing items will cause HMAC validation errors on their retrieval.
/WEB-INF/infinispan-stateless-dynamodb.xml
- DynamoDB consistent reads for "sessionStore.sessionMap" can be enabled by setting the "dynamodb.consistentReads.sessionStore.sessionMap" Java system property to true.

Web API

/authz-sessions/rest/v3/
- The consent prompt "claims" parameter adds support for verified claims requests (OpenID Connect Identity Assurance 1.0) with multiple verifications.
  
  The "claims" -> "new" -> "essential", "voluntary" arrays will list the requested verified claims (prefixed with "verified:") across all "verified_claims" elements (if multiple are found).
  
  The "claims" -> "verification" -> "id_token", "userinfo" objects will include the first found verification element (if multiple are found), the full list of verification objects can be obtained by parsing the "claims" -> "raw_request" parameter (requires op.authz.includeRawClaimsRequestInPrompt=false).
/monitor/v1/metrics
- Adds new ".dynamoDB.invalidItemHmacCounter" metric of type counter for Connect2id server deployments with a DynamoDB database. Counts the number of retrieved DynamoDB items which failed the HMAC SHA-256 check (if enabled).

SPI

PasswordGrantHandler, JWTGrantHandler, SAML2GrantHandler
- Consented claims which name is prefixed with "id_token:" will be included in the ID token instead of via the default method, the UserInfo endpoint. This feature is adopted from the authorisation session web API.
Included OpenID Connect HTTP claims source
- Updates the included AdvancedClaimsSource SPI implementation for sourcing OpenID claims from an HTTP endpoint to version 2.1 (com.nimbusds:oidc-claims-source-http:2.1). The JSON object representing the request will now include a "claims_transport" parameter hinting how the requested claims are going to be transported to the relying party: "userinfo" for the UserInfo endpoint, "id_token" for the ID token, omitted if not applicable (for claims requested by an internal plugin, such as an access token codec).

Resolved issues

OpenID claims requests with JSON array of verified_claims must not fail (issue server/605).
Fixes NPE in OpenID Connect Federation 1.0 client registration error processing logic (issue server/585).
Front-channel logout requests must not include the issuer identifier (iss) as query parameter when a session identifier (sid) isn't included (issue server/595).
Updates the OAuth 2.0 authorisation endpoint to reject signed (JWS) request objects (JARs) where the optional JWT "sub" (subject) claim is set to the client_id value, see the latest cross-JWT confusion security recommendation in https://tools.ietf.org/html/draft-ietf-oauth-jwsreq-29#section-10.8 (issue server/588).
Fixes the reported "request" (JAR) parameter name in illegal_request error messages from the OAuth 2.0 authorisation endpoint (issue server/589).
Ignore unknown key types in a JWK set, when parsing a client JWK set and in other cases (issue nimbus-jose-jwt/377).
Logs at INFO level the enabled / disabled status of every loaded claims source at Connect2id server startup under OP7107 (issue server/600).
Logs at TRACE level the decoded self-contained access token authorisation under AS0544 (issue authz-server/178).
HTTP POST and PUT requests to the client registration endpoint where the entity body exceeds the hard-wired character limit must return a HTTP 400 Bad Request, not HTTP 500 Internal Server Error. Raises the limit from 15 thousand to 20 thousand characters (issue server/579).

10.0 (2020-08-18)

Summary

Supports OpenID Connect Federation 1.0 (draft 12) with explicit client registration. The extension to OpenID Connect enables seamless single sign-on and identity provisioning in a federation of OpenID providers and relying parties approved by one or more operators (trust anchors), potentially involving intermediate authorities. See https://openid.net/specs/openid-connect-federation-1_0-12.html
Enables issue of refresh tokens for transient (non-persisted) authorisations, where the authorisation data is contained in the refresh token (as encrypted JWT). Previously refresh tokens could be issued only for long-lived (persisted) authorisations, where the refresh token is an encrypted key pointing to the authorisation record. The Connect2id server can issue an unlimited number of self-contained refresh tokens for a given client and subject (end-user). This can be useful in cases where an end-user has instances of a public client on several devices, but the granted authorisations must not be shared between the client instances. Revocation applies to all client instances.
Supports setting of global or client-specific policy for enforcing use of pushed authorisation requests (PAR) only, and rejecting regular requests at the authorisation endpoint (including JAR). The new op.par.require configuration sets the global PAR policy. The new require_pushed_authorization_requests client metadata parameter sets the PAR policy for an individual OAuth 2.0 client. Clients which must use PAR will receive an invalid_request error with message "PAR required" from the authorisation endpoint if they attempt a regular request. See OAuth 2.0 Pushed Authorization Requests (draft-ietf-oauth-par-02).
The authorisation store web API receives a new version with endpoint /authz-store/rest/v3 with an updated "revocation" resource, to handle revocation of non-persisted authorisations tied to self-contained refresh tokens. The previous web API version at endpoint /authz-store/rest/v3 remains available.
Supports the tls_client_certificate_bound_access_tokens client metadata parameter from OAuth 2.0 Mutual-TLS Client Authentication and Certificate-Bound Access Tokens (RFC 8705). Intended for enforcing issue of X.509 client certificate bound access tokens to a public (non-authenticating) client. The client must present a client certificate (self-signed or CA issued) at the token endpoint; if no certificate is presented the client will receive an invalid_client token error response with HTTP status code 401 Unauthorized.
Supports configuration of unlimited additional access tokens for the Connect2id server integration web APIs, to facilitate token roll-over and for other purposes.
Upgrades the OAuth 2.0 / OpenID Connect SDK to major release 8.0 which removes the deprecated javax.mail dependency and all deprecated API methods relying on its classes. ClaimsSource and AdvancedClaimsSource SPI implementations which rely on the javax.mail.Address class for the "email" claim need to switch to an alternative java.lang.String based getter / setter method of the UserInfo class.

Configuration

/WEB-INF/federationJWKSet.json -- New JSON Web Key (JWK) set file for configuring one or more RSA keys for signing the issued federation entity statements. The RSA keys must have a size of 2048 bits, a unique key identifier (kid), a key use (use) set to signature (sig) and an algorithm (alg) set to RS256. The first RSA JWK in the list will be used for signing. Previously used keys to facilitate roll-over can follow. The federation JWK set can be alternatively passed via a op.federationJWKSet Java system property, optionally with additional BASE64URL encoding to avoid shell escaping of special JSON characters.

9.4 (2020-05-20)

Summary

Adds support for issuing EdDSA signed JWT-encoded access tokens. Choose EdDSA (RFC 8037) for increased performance and compact signatures. Connect2id benchmarks show EdDSA signature generation with an Ed25519 key receiving a 62x boost over 2048-bit RSA (RS256), with verification remaining roughly on par. The JWT signature size is reduced 4 fold.

To roll-over to EdDSA signed JWT-encoded access tokens provision the Connect2id server JWK set with a signing Ed25519 key and set the JWS algorithm for access tokens to "EdDSA". Check the configuration notes for details.

Configuration

/WEB-INF/jwkSet.json
- Introduces a new optional Ed25519 octet key pair JWK (key type "OKP") with curve "Ed25519", use "sig" (signature) and requiring a unique key ID. Intended for issuing EdDSA signed JWT-encoded access tokens. To generate and roll-over the EdDSA signing key you can use the latest available Connect2id server JWK set generator, see https://connect2id.com/products/server/docs/config/jwk-set#generation
/WEB-INF/authzStore.properties
- authzStore.accessToken.jwsAlgorithm -- Adds support for signing issued JWT-encoded access tokens with the "EdDSA" JWS algorithm (RFC 8037). Requires the Connect2id server JWK set to be provisioned with a signing Ed25519 key. The default JWS algorithm for signing remains "RS256" with an 2048-bit RSA key due to the ubiquitous JWT library support for RS256.

Resolved issues

Calls to the ClaimsSource from a TokenIntrospectionResponseComposer SPI implementation should automatically include any "claims_data" if available for the introspected access token (issue server/561).
Fixes a bug which prevented persistence of client registrations into an SQL database where the client_id contains a colon (:) character in combination with some non-alphanumeric characters preceding it. Affected the single-tenant edition of the Connect2id server (issue server/563).

/WEB-INF/infinispan-*-{mysql|postgres95|sqlserver|h2}.xml
- Updates the SQL store schema to v2.7 and switches to a single shared database connection pool for all Infinispan map and cache structures used by the Connect2id server. Support for per map / cache connection pool to spread the load over multiple databases (vertical partitioning) is still available.
/WEB-INF/infinispan-*-dynamodb.xml
- Updates the DynamoDB store schema to v1.7 and adds support for configuring an optional HTTP proxy for connections to the DynamoDB endpoint. The HTTP proxy is configured by setting the Java system properties "dynamodb.httpProxyHost" and "dynamodb.httpProxyPort".

Web API

/authz-sessions/rest/v3/
- Exposes the optional "id_token_hint" OpenID authentication request parameter in the authorisation session object (under "auth_req").

SPI

Upgrades the Connect2id server SDK to com.nimbusds:c2id-server-sdk:4.20
com.nimbusds.openid.connect.provider.spi.tokens.response.CustomTokenResponseComposer
- New SPI for composing custom token success and error responses. Can be used to include additional parameters in an access token response based on the authorisation (consent) "data" parameter, such as an "authorization_details" parameter required in OAuth 2.0 Rich Authorization Requests (draft-lodderstedt-oauth-rar-03).

Resolved issues

Previously consented claims appearing in the consent prompt (authorisation session API) must not include language tags. Fixed a bug which prevented stripping of the tags from claim names retrieved from the "clm" field in authorisation records (issue server/558).
Enhances the authorisation session API by automatically stripping language tags in the names of consented claims (issue server/559).

9.2 (2020-04-21)

Summary

Updates support for "JWT Secured Authorization Request (JAR)" to draft-ietf-oauth-jwsreq-21. client_id becomes the sole required query parameter for JAR requests, in addition to the query parameter for the JWT itself (request for a JWT passed inline or request_uri for a JWT passed by URI reference).
Adds new "op.authz.oAuthRequestJWTPolicy" configuration setting for specifying a policy for merging unsecured parameters in a JWT-secured OAuth 2.0 authorisation request (JAR) (excluding OpenID authentication requests). The default policy is to accept only the JWT-secured parameters, with unsecured query parameters being ignored.
Adds new "op.authz.openIDRequestJWTPolicy" configuration setting for specifying a policy for merging unsecured parameters in a JWT-secured OpenID authentication request. The default policy is merge unsecured OpenID authentication request query parameters, with the JWT-secured parameters having precedence.

Configuration

/WEB-INF/oidcProvider.properties
- New "op.authz.oAuthRequestJWTPolicy" configuration setting for specifying a policy for merging unsecured parameters in a JWT-secured OAuth 2.0 authorisation request (JAR) (excluding OpenID authentication requests).
  
  Supported policies:
  - STRICT -- Use only JWT-secured parameters, unsecured query parameters will be ignored. This is the default policy for OAuth 2.0 authorisation requests.
  - MERGE_UNSECURED -- Merge unsecured authorisation request query parameters, with the JWT-secured parameters having precedence.
- New "op.authz.openIDRequestJWTPolicy" configuration setting for specifying a policy for merging unsecured parameters in a JWT-secured OpenID authentication request.
  
  Supported policies:
  - STRICT -- Use only JWT-secured parameters, unsecured query parameters will be ignored.
  - MERGE_UNSECURED -- Merge unsecured OpenID authentication request query parameters, with the JWT-secured parameters having precedence. This is the default policy for OpenID authentication requests.

Resolved issues

Adds missing AccessTokenKeyExternalizer and AccessTokenAuthorizationExternalizer declarations for "authzStore.idAccessTokenMap" in the infinispan-*.xml configs (issue server/545).
Fixes handling of GeneralException instances thrown from ClaimSource SPIs when no error code and HTTP status code is specified. The correct response is to return an HTTP status code 500 instead of an empty UserInfo (issue server/547).
Fixes "userInfoEndpoint.serverErrors" metering on a ClaimsSource SPI throwing an unchecked Exception or a GeneralException (with no parameters) instance (issue server/548).
Fixes the supply of optional claims data to ClaimsSource SPI implementations for OpenID claims requests for ID tokens (issue server/549).

Resolved issues

Fixes premature expiration of OAuth 2.0 authorisation codes resulting from prompt=none or persisted consent authorisations in stateless Connect2id server deployments (single node or cluster) with an SQL RDBMS database (MySQL, PostgreSQL, Microsoft SQL server). Applies to Infinispan configurations infinispan-stateless-{mysql|postgres95|sqlserver}.xml (where Redis is not used as an in-memory cache / store). Affected deployments should update (issue authz-store/176).
Adds debug logging for authorisation grant put (AS0230) and authorisation grant retrieval (AS0222) (issues authz-store/174 and 175).

Web API

/token/introspect
- Updates "JWT Response for OAuth Token Introspection" support to the upcoming draft-ietf-oauth-jwt-introspection-response-09 version.
  
  For a client (resource server) to obtain a JWT-secured introspection response it must submit an introspection request with the Accept HTTP request header set to "application/token-introspection+jwt". The request must be authorised with the registered client authentication method or with an access token.
  
  The JWT response will be JWS signed and include the following JWT claims:
  - "iss" -- Set to the OpenID Provider / Authorisation server issuer URL.
  - "aud" -- Set to the client_id of the caller (resource server).
  - "iat" -- The issue timestamp.
  - "token_introspection" -- A JSON object containing the token introspection response members, such as "active", etc.
  The optional op.token.introspection.jwtType configuration property that overrides the JWT "typ" (type) header applies.
  
  Legacy JWT-secured introspection responses (according to draft-ietf-oauth-jwt-introspection-response-09) will continue to be supported, for a client (resource server) to request one the Accept HTTP request header must be set to "application/jwt".

SPI

9.0 (2020-03-18)

Summary

Updates support for OpenID Connect for Identity Assurance 1.0 to draft 09 (see https://openid.net/specs/openid-connect-4-identity-assurance-1_0-09.html). Requested verified claims will now be automatically marked and processed as such in the authorisation session API. The requested "verification" and individual claim "purpose" parameters will be presented in the consent prompt.
Updates the authorisation session API and the OAuth 2.0 grant handler SPIs to enable passing of additional JSON data with requests to the configured claims source(s). This can be used to pass claim values from the authorisation handler or when implementing Identity Assurance the necessary verification element for verified claims in the UserInfo response or the ID token.

The included HTTP-based claims source SPI implementation is updated to include a "claims_data" parameter (of type JSON object) in the request to represent the optional claims data.
Upgrades the Infinispan and backend database schemas for the identifier-based access tokens and the long-lived (persisted) authorisation records.

On startup the Connect2id server will automatically create the new required "id_access_tokens" and "long_lived_authorizations" table columns for a relational MySQL, PostgreSQL or Microsoft SQL Server database.

Connect2id server deployments with an LDAP v3 backend database (such as OpenLDAP or OpenDJ) need to update the LDAP schema manually to version 1.12 see https://bitbucket.org/connect2id/server-ldap-schemas/src/1.10/ , the OpenLDAP schema diff https://bitbucket.org/connect2id/server-ldap-schemas/diff/src/main/resources/ oidc-authz-schema-openldap.ldif?at=1.12 &diff1=49115daf531b48c2d9fd0f766721d84c28576eae &diff2=4c78a00734bfeb9abdd4c9dec76d9fbc51216faa and the OpenDJ schema diff https://bitbucket.org/connect2id/server-ldap-schemas/diff/src/main/resources/ oidc-authz-schema-opendj.ldif?at=1.12 &diff1=49115daf531b48c2d9fd0f766721d84c28576eae &diff2=4c78a00734bfeb9abdd4c9dec76d9fbc51216faa

Connect2id server deployments with a DynamoDB database are essentially schema-less and no specific action is required.

Configuration

/WEB-INF/oidcProvider.properties
- New "op.token.introspection.jwtType" configuration property. Sets the "typ" (type) header of JWT introspection responses. The default value is "token-introspection+jwt". This configuration allows the type header to be set to "JWT" for non-compliant clients and JWT libraries which cannot handle header values other than "JWT".
/WEB-INF/log4j.xml
- Adds an optional console (SYSTEM_OUT) appender. Setting the Java system property log4j.loggers.root.appender to console switches logging from the rolling-file appender to the standard output. Can be useful in container deployments.

Web API

/authz-sessions/rest/v3/
- The consent prompt identifies requested verified OpenID claims by prefixing their name with "verified:", for example "verified:given_name", "verified:family_name" or "verified:address". When submitting consent to the Connect2id server the names of the verified claims must also be prefixed with "verified:".
  
  To process verified OpenID claims OpenID Connect for Identity Assurance 1.0 must be enabled (op.assurance.supportsVerifiedClaims=true).
- The consent prompt is updated to include the optional "purpose" attribute of requested verified OpenID claims (OpenID Connect for Identity Assurance 1.0) as well as regular claims. If the attribute is set for one or more claims the purpose strings will appear in a new claims.purposes JSON object containing the claim name / purpose string pairs.
  
  The accepted purpose string length is between 3 and 300 characters, according to the Assurance specification. The Relying Party may use the "ui_locales" OpenID authentication request parameter to set the preferred language for the purpose strings.
  
  In order to prevent injection attacks all special characters in a purpose string must be escaped before shown in a user interface.
- The consent prompt is updated to include the optional "verification" JSON object for a requested verified claims set (OpenID Connect for Identity Assurance 1.0). If the verification element is set for a requested verified claims set to be returned in the UserInfo response it will appear in a new claims.verification.userinfo JSON object. Likewise, if the element is set for a requested claims set to be returned with the ID token it will appear in a claims.verifiction.id_token JSON object.
  
  To include the "verification" element in the consent prompt OpenID Connect for Identity Assurance 1.0 must be enabled (op.assurance.supportsVerifiedClaims=true).
- The consent is updated to include an optional "claims_data" JSON object parameter. The data will be made available in the ClaimsSourceRequestContext.getClaimsData method when the configured claims source(s) get called at the UserInfo endpoint or when feeding the consented claims into the ID token.
  
  The "claims_data" can be used to provision entire claims from the authorisation session and the front-channel. It can also be used in Identity Assurance to construct the "verification" element in the authorisation session and then have it included in the UserInfo response, for example in remote in-person proofing scenarios.
  
  The "claims_data" will be included in the issued access token and in long-lived (persisted) authorisations in a new "cld" (claims data) JSON object field. To keep the claims data confidential from the relying party (client) either an identifier access token encoding must be chosen (access_token.encoding = IDENTIFIER in the consent) or if a self-contained (JWT) encoding is chosen the JWT must be additionally encrypted (access_token.encrypt = true).
  
  An AdvancedClaimsSource SPI implementation can retrieve the claims data JSON object by a call to the ClaimsSourceRequestContext.getClaimsData method.
/authz-store/rest/v2/authorizations
- The OAuth 2.0 / OpenID Connect authorisations includes a new optional "cld" (claims data) JSON object field to represent claims data to be passed to the OpenID claims source(s) with access tokens consumed at the UserInfo endpoint.
/token/introspect
- The access token introspection response includes a new optional "cld" (claims data) JSON object field to represent claims data to be passed to the OpenID claims source(s) with access tokens consumed at the UserInfo endpoint.

SPI

Upgrades the Connect2id server SDK to com.nimbusds:c2id-server-sdk:4.18

com.nimbusds.openid.connect.provider.spi.claims.ClaimsSource, AdvancedClaimsSource
- The names of verified OpenID claims passed via the "claims" argument of the "getClaims" method will be prefixed with "verified:" by the Connect2id server (OpenID Connect for Identity Assurance 1.0).
com.nimbusds.openid.connect.provider.spi.claims.ClaimsSourceRequestContext
- Adds new "getClaimsData" method to obtain optional data set by an authorisation handler to fulfill OpenID claims provision, for example to construct the "verification" element for a verified claims set (OpenID Connect for Identity Assurance 1.0).
com.nimbusds.openid.connect.provider.spi.tokens.AccessTokenAuthorization
- Adds new "getClaimsData" method to the interface to represent OpenID claims fulfillment data. The default implementation returns null.
com.nimbusds.openid.connect.provider.spi.grants.BasicClaimsSpec
- Adds new constructor and "getData" method for passing optional claims fulfillment data to the configured OpenID claims source(s).

Resolved issues

Fixes a security bug which caused the Connect2id server to redirect to a supplied invalid redirect_uri in a OAuth 2.0 authorisation request when the request includes a request object that doesn't parse to a valid JWT and the "redirect_uri" is present as top-level parameter. The redirection will occur with the error code and description from the failed request. The correct behaviour is to not redirect back to the client with an error unless the client_id and the redirect_uri are valid. Deployments are advised to update to prevent potential misuse of such redirections (issue server/537).
Fixes a bug introduced in Connect2id server 8.1 which prevented output of the "verification" element in the OpenID "claims" authentication parameter output in /authz-sessions/rest/v3/ GET responses. The bug was caused by a faulty consent-all keyword sanitization (issue server/532).
Removes an erroneous standard output print (issue server/535).

8.2 (2020-02-25)

Configuration

/WEB-INF/oidcProvider.properties
- "op.token.authMethods" -- Basic authentication ("client_secret_basic") is no longer required when configuring the enabled client authentication methods. Connect2id server deployments can now be configured with a single enabled client authentication method other than Basic, for example with "self_signed_tls_client_auth" only for client X.509 certificate authentication.
  
  The first authentication method (ignoring "none") in the list will now specify the default method for clients which don't set one explicitly during registration.
/WEB-INF/authzStore.properties
- New "authzStore.refreshToken.defaultLifetime" configuration property. Specifies a default refresh token lifetime in seconds. Can be overridden by individual authorisations. If zero or omitted defaults to permanent (no expiration). Must be zero or a positive integer. The default value is zero (no expiration).
/WEB-INF/cors.properties
- Any property in the configuration file can be overridden with a Java system property, e.g. by setting the optional -D argument at JVM startup -Dcors.allowOrigin=https://example.com

Web API

/authz-sessions/rest/v3/
- Includes the OpenID authentication request "purpose" parameter (from OpenID Connect for Identity Assurance 1.0) in the "auth_req" JSON object which exposes selected request parameters when the authorisation session is queried with a GET. Normally the "purpose" parameter is only provided during the consent step. With this the logic page can access it at any one time during the authorisation session.

Resolved issues

Fixes the URL encoding of the query parameters in front-channel logout notification URIs. The query parameters were receiving a double URL encoding (issue server/520).
Fixes an OpenID "claims" request parameter sanitisation bug which prevented output of the parameter in the consent prompt when op.authz.includeRawClaimsRequestInPrompt is enabled (issue server/523).
Updates the UserInfo endpoint to log (INFO level, log line with ID OP7301) the missing token scope if a bearer token error "insufficient_scope" is returned (issue server/517).

8.1 (2020-02-03)

Summary

Updates mTLS client authentication by accepting client X.509 certificates with additional URL-encoding on top of the PEM encoding when the certificate is received from a TLS termination proxy via the HTTP security header configured by "op.tls.clientX509CertHeader".
Adds a new "authzStore.options.issueLegacyRefreshTokens" configuration property to facilitate seamless rolling cluster upgrades from Connect2id server 7.x and earlier versions to 8.x. When this setting is enabled Connect2id server 8.1 instances will issue refresh tokens in the old encoding supported and recognised in 7.x (instead of the new refresh token encoding with additional encryption of metadata, introduced in 8.0). After the rolling upgrade is completed and all instances are 8.1 the setting can be disabled (on a subsequent upgrade) to start issuing new refresh tokens with the new encoding.

Configuration

/WEB-INF/oidcProvider.properties
- Client X.509 certificates received with the HTTP security header configured by "op.tls.clientX509CertHeader" can have an optional additional URL-encoding (also called percent encoding) of the PEM-encoded string. The presence of additional URL-encoding is automatically detected.
/WEB-INF/authzStore.properties
- New "authzStore.options.issueLegacyRefreshTokens" configuration property. If true the Connect2id server will issue refresh tokens in the legacy format supported up to v7.x. Intended to facilitate seamless rolling cluster upgrades to v8.x and later without producing invalid_grant errors when a new 8.x refresh token is used at a Connect2id server 7.x instance. The default value is false (no issue of legacy refresh tokens).

Resolved issues

Fixes parse exception reporting when reading DynamoDB items from "pending_codes" and "id_access_tokens", logs JSON with error message (issue authz-store/169).
Fixes loading of OAuth 2.0 grant handler SPIs when multiple implementations are available (broken in Connect2id server 8.0, issue server/515).
Logs the names of the OAuth 2.0 grant handler SPI classes when multiple are enabled for a given grant type (issue server/515).
Logs the names of an SPI class when a single must be loaded and multiple are available (issue common/60).
Disables the setting of the "jsessionid" cookie in the Connect2id server banner page (index.jsp) as no cookie or session is required by the page (issue server/516).

8.0 (2020-01-01)

Summary

Supports OAuth 2.0 Pushed Authorization Requests. See https://tools.ietf.org/html/draft-ietf-oauth-par-00
Supports OpenID Connect for Identity Assurance 1.0 (draft 08). See https://openid.net/specs/openid-connect-4-identity-assurance-1_0.html
The default self-contained (JWT) access token codec implementing the SelfContainedAccessTokenClaimsCodec SPI now supports multiple JWT profiles:
- c2id-1.1 -- Connect2id server specific profile, available since v7.17, with the JWT "typ" (type) header set to "at+jwt".
- c2id-1.0 -- Connect2id server specific profile, available since v1.0, outputs identical JWT claims as c2id-1.1 but doesn't set the JWT "typ" (type) header.
- oauth-1.0 -- Standard profile in development at the OAuth working group, see draft-ietf-oauth-access-token-jwt-03
The active JWT profile for access tokens is selected by a new optional "authzStore.accessToken.codec.jwt.profile" configuration property.
Consented OpenID claims can now be fed into the access token by prefixing their name with "access_token:". For example, "access_token:email" will cause the "email" claim to be retrieved from the configured OpenID claims source and fed into each access token for the given OAuth 2.0 grant. If the access token is self-contained (JWT) the "email" claim will be added as a top-level claim with the same name. If the access token is identifier-based the "email" claim will appear as top-level claim in the token introspection response.

Two additional prefixes are supported:
- "access_token:uip:" -- Causes the OpenID claim to be merged into the top-level "uip" (optional preset UserInfo claims) JSON object claim.
- "access_token:dat:" -- Causes the OpenID claim to be merged into the top-level "dat" (optional data) JSON object claim.
If the claim name clashes with an existing top-level access token claim it will be ignored and not fed into the access token.
Identifier-based (or key-based) access tokens are now stored in hashed form (SHA-256 truncated to 128 bits) to prevent token leakage if the database or a database backup is exposed and the HMAC SHA-256 key (the Connect2id server JWK with key ID "hmac") to attach an authenticity and integrity code to each token identifier is also compromised. Previously the only protection against undetected token identifier leaks from the database or a backup was the HMAC SHA-256 key remaining secret.

When upgrading to Connect2id server 8.0 if there are existing identifier-based access tokens in the database issued by a previous Connect2id server version the "authzStore.options.legacyPlainKeysInStorage" configuration property can be set to true to enable their successful introspection, otherwise they will be deemed invalid.
Upgrades the Infinispan and backend database schemas for the identifier-based access tokens.

On startup the Connect2id server will automatically create the new required "id_access_tokens" table columns for a relational MySQL, PostgreSQL and Microsoft SQL Server databases.

Connect2id server deployments with an LDAP v3 backend database (such as OpenLDAP or OpenDJ) need to update the LDAP schema manually to version 1.10 see https://bitbucket.org/connect2id/server-ldap-schemas/src/1.10/ , the OpenLDAP schema diff https://bitbucket.org/connect2id/server-ldap-schemas/diff/src/main/resources/ oidc-authz-schema-openldap.ldif?at=1.10 &diff1=d9599b598753ec3037b784b29baeac0e28bf7615 &diff2=49115daf531b48c2d9fd0f766721d84c28576eae and the OpenDJ schema diff https://bitbucket.org/connect2id/server-ldap-schemas/diff/src/main/resources/ oidc-authz-schema-opendj.ldif?at=1.10 &diff1=d9599b598753ec3037b784b29baeac0e28bf7615 &diff2=49115daf531b48c2d9fd0f766721d84c28576eae

Connect2id server deployments with a DynamoDB database are essentially schema-less.

Connect2id server deployments with Redis as the primary in-memory and caching store use a new bucket (database) with number 14 to store tokens in the new format. Cached tokens in the old format in Redis bucket 4 will remain there until they expire.
Introduces a new AES JSON Web Key (JWK) in the Connect2id server JWK set for encrypting and authenticating refresh tokens without the need for a database lookup. The encryption will also enable the inclusion of additional metadata and the implementation of advanced security measures in future Connect2id server versions. Existing refresh tokens without the additional encryption layer will continue to be valid and will be handled transparently.

Configuration

/WEB-INF/jwkSet.json
- Introduces a new AES 256 bit octet sequence JWK with use "enc" (encryption) and ID "refresh-token-encrypt" for encrypting issued refresh tokens. This key is required, starting from Connect2id server 8.0.
/WEB-INF/oidcProvider.properties
- New "op.par.lifetime" configuration property which sets the lifetime of the pushed authorisation requests (PAR), in seconds. Must not be shorter than 10 seconds. The default value is 60 seconds.
- New "op.authz.includeRawClaimsRequestInPrompt" configuration property which enables / disables inclusion of the raw OpenID "claims" request parameter in the consent prompts of the authorisation session web API, under "claims" -> "raw_request". Access to the raw "claims" request parameter may be required when processing requests for verified claims (OpenID Connect for Identity Assurance 1.0). The default values is false (disabled).
- New "op.assurance.supportsVerifiedClaims" configuration property which enables / disables advertisement of OpenID Connect for Identity Assurance 1.0 support in OpenID provider metadata and inclusion of the optional transaction specific "purpose" OpenID authentication parameter in the consent prompts of the authorisation session web API. Corresponds to the "verified_claims_supported" OpenID provider metadata parameter. The default values is false (disabled).
- New "op.assurance.supportedTrustFrameworks" configuration property. Lists the supported trust frameworks if OpenID Connect for Identity Assurance 1.0 support is enabled. Corresponds to the "trust_frameworks_supported" OpenID provider metadata parameter.
- New "op.assurance.supportedIdentityEvidenceTypes" configuration property. Lists the supported identity evidence types if OpenID Connect for Identity Assurance 1.0 support is enabled. Corresponds to the "evidence_supported" OpenID provider metadata parameter.
- New "op.assurance.supportedIDDocumentTypes" configuration property. Lists the supported ID document types if OpenID Connect for Identity Assurance 1.0 support is enabled. Corresponds to the "id_documents_supported" OpenID provider metadata parameter.
- New "op.assurance.supportedIdentityVerificationMethods" configuration property. Lists the supported identity verification methods if OpenID Connect for Identity Assurance 1.0 support is enabled. Corresponds to the "id_documents_verification_methods_supported" OpenID provider metadata parameter.
- New "op.assurance.supportedVerifiedClaims" configuration property. Lists the supported verified claims if OpenID Connect for Identity Assurance 1.0 support is enabled. Corresponds to the "claims_in_verified_claims_supported" OpenID provider metadata parameter.
/WEB-INF/authzStore.properties
- New "authzStore.accessToken.codec.jwt.profile" configuration property. Sets the JWT profile to use for access tokens minted by the default self-contained access token codec. See the SelfContainedAccessTokenClaimsCodec SPI JavaDoc for more information.
  
  Supported profiles:
  - c2id-1.1 -- Connect2id server specific profile, available since v7.17, with the JWT "typ" (type) header set to "at+jwt".
  - c2id-1.0 -- Connect2id server specific profile, available since v1.0, outputs identical JWT claims as c2id-1.1 but doesn't set the JWT "typ" (type) header.
  - oauth-1.0 -- Standard profile in development at the OAuth working group, see draft-ietf-oauth-access-token-jwt-03
  The default value is c2id-1.1.
- New "authzStore.options.legacyPlainKeysInStorage" configuration property. If true the Connect2id server will support retrieval of legacy plain keys for identifier-based access tokens from storage after upgrading to Connect2id server 8.x, false to ignore such keys which will cause the introspection of the linked access tokens to flag them as invalid. Note that enabling this configuration causes additional database reads and a performance penalty during introspection. The default value is false (no support for legacy plain access token keys).
/WEB-INF/log4j.xml
- The root logger level ("INFO") can now be overridden by setting the "log4j.level" Java system property.
/WEB-INF/infinispan-*.xml
- Updates the data structure for the identifier-based access tokens, which is now named "authzStore.idAccessTokenMap".
/WEB-INF/infinispan--redis-.xml
- Deployments using Redis as primary caching and in-memory store will use a new bucket with number 14 for the identifier-based access tokens. Cached tokens in the old format in Redis bucket 4 will remain there until they expire.

Web API

/par
- New endpoint for receiving back-channel OAuth 2.0 authorisation and OpenID authentication requests, also called Pushed Authorization Requests (PAR). Confidential clients must authenticate with the same registered method as for the token endpoint. The complete specification is at https://tools.ietf.org/html/draft-ietf-oauth-par-00

- If op.authz.includeRawClaimsRequestInPrompt=true the raw OpenID "claims" request parameter will be included in the consent prompt API responses (as JSON object member "claims" -> "raw_request").
- If OpenID Connect for Identity Assurance 1.0 is enabled (op.assurance.supportsVerifiedClaims=true) and the OpenID authentication request includes the transaction specific purpose parameter, the parameter will be included in the consent prompt API responses (as JSON object member purpose).
- The "claims" parameter of the consent objects enables OpenID claims to be fed into the access token by prefixing their name with "access_token:". For example, "access_token:email" will cause the "email" claim to be retrieved from the configured OpenID claims source and fed into each access token for the given OAuth 2.0 grant. If the access token is self-contained (JWT) the "email" claim will be added as a top-level claim with the same name. If the access token is identifier-based the "email" claim will appear as top-level claim in the token introspection response.
  
  Two additional prefixes are supported:
  - "access_token:uip:" -- Causes the OpenID claim to be merged into the top-level "uip" (optional preset UserInfo claims) JSON object claim.
  - "access_token:dat:" -- Causes the OpenID claim to be merged into the top-level "dat" (optional data) JSON object claim.
  If the claim name clashes with an existing top-level access token claim it will be ignored and not fed into the access token.

- Adds new meters for the Pushed Authorisation Request (PAR) endpoint:
  - "parEndpoint.successfulRequests" -- Meters successful PAR requests.
  - "parEndpoint.invalidRequests" -- Meters invalid PAR requests.
  - "parEndpoint.invalidClientErrors" -- Meters "invalid_client" errors at the PAR endpoint.
  - "parEndpoint.serverErrors", serverErrors -- Meters server errors (HTTP 500) at the PAR endpoint.

SPI

Upgrades the Connect2id server SDK to com.nimbusds:c2id-server-sdk:4.12

com.nimbusds.openid.connect.provider.spi.par.PARValidator
- New SPI for performing additional validation of received Pushed Authorisation Requests (PAR). See https://www.javadoc.io/doc/com.nimbusds/c2id-server-sdk/4.12/ com/nimbusds/openid/connect/provider/spi/par/PARValidator.html
com.nimbusds.openid.connect.provider.spi.tokens
- The self-contained and identifier-based access token codecs can now be configured via Connect2id server properties which are obtained by calling the TokenCodecContext.getCodecProperties method, for example to enable support of multiple token profiles.
- The self-contained access token codec interface (SelfContainedAccessTokenClaimsCodec) is extended with new advancedEncode and advancedDecode methods to enable setting and validation of the JWT "typ" (type) header.
- The AccessTokenAuthorization interface adds support for custom top-level access token claims via the new getOtherTopLevelParameters method.

Resolved issues

Fixes the expiration logic for refresh tokens when the Connect2id server is configured with authzStore.refreshToken.alwaysUpdate=true (issue authz-store/166).
Fixes "authzStore.accessTokenIssues" metering on successful refresh token usage (issue authz-store/167).
Fixes persistence of client_id metadata for cached request_uri claims in multi-tenant Connect2id server deployments (issue server/507).
Updates AWS SDK to 1.11.632 to support IAM role for Amazon EKS (issue server/503).
