Session store
The Connect2id server includes a store for the end-user sessions. Its configuration properties are located in
WEB-INF/sessionStore.properties
The configuration properties are grouped into sections:
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:
-DsessionStore.maxLifetime=-1
The external configuration guide has tips for setting system properties from environment variables, local files and other locations.
1. Web API
sessionStore.apiAccessTokenSHA256
The access token for the subject session store 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 will be disabled.
The hash for a token with value ztucZS1ZyFKgh0tUEruUtiSTXhnexmd6:
sessionStore.apiAccessTokenSHA256=cca68b8b82bcf0b96cb826199429e50cd95a042f8e8891d1ac56ab135d096633
sessionStore.secondaryAPIAccessTokenSHA256
Optional secondary access token for the subject session store web API. Has the same format as sessionStore.apiAccessTokenSHA256. Can be used to facilitate token roll-over. Must not be set if not needed.
sessionStore.secondaryAPIAccessTokenSHA256=304b07b6d8eb155a957b965831be9ce39fb098554a2d5f2047ee0a0491022dea
2. Session defaults and policies
sessionStore.maxLifetime
The default maximum session lifetime, in minutes. Applied to newly created
subject sessions where the
max_life value has been omitted. A negative value means no time limit. Must
not be zero.
The maximum session lifetime is used in conjunction with the maximum authentication lifetime and the maximum idle time to determine when a session should expire (whichever time event occurs first).
To set the default maximum session lifetime to 14 days (20160 minutes):
sessionStore.maxLifetime=20160
sessionStore.authLifetime
The default maximum authentication lifetime, in minutes. Applied to newly
created subject sessions where
the auth_life value has been omitted. A negative value means no time limit.
Must not be zero.
The maximum authentication lifetime is used in conjunction with the maximum lifetime and the maximum idle time to determine when a session should expire (whichever time event occurs first).
To set the default maximum authentication lifetime to 24 hours (1440 minutes):
sessionStore.authLifetime=1440
sessionStore.maxIdleTime
The default maximum session idle time, in minutes. Applied to newly created
subject sessions where the
max_idle value has been omitted. A negative value means no time limit. Must
not be zero.
The maximum idle time is used in conjunction with the maximum lifetime and the maximum authentication lifetime to determine when a session should expire (whichever time event occurs first).
To set the default maximum idle time to 24 hours (1440 minutes):
sessionStore.maxIdleTime=1440
sessionStore.quotaPerSubject
The maximum number of concurrent sessions a subject may have across browsers and devices. Should typically be set to not more than ten concurrent sessions.
To set the maximum number of concurrent session to five:
sessionStore.quotaPerSubject=5
sessionStore.onQuotaExhaustion
The login behaviour when a subject exhausts their session quota.
Policy values:
-
DENY_LOGIN– The login request must be rejected. -
CLOSE_OLD_SESSION– The next expiring session for the subject must be closed and the new login request must be allowed to proceed.
To set the policy to CLOSE_OLD_SESSION:
sessionStore.onQuotaExhaustion=CLOSE_OLD_SESSION
sessionStore.acceptLegacySIDs
Set to true to accept legacy session identifiers (SID) without HMAC
protection. Required to enable import of
sessions from Connect2id server
versions 5x and older. The default value is false.
sessionStore.acceptLegacySIDs=false
3. Internal configuration
sessionStore.internal.subjectIndexPurgeInterval
The interval for purging orphaned subject index keys, in seconds. If -1 the
purge thread is disabled. If 0 the Connect2id server will set the interval
heuristically, depending on the Infinispan configuration (1 day for stateless
deployments with Redis or DynamoDB, disabled in all other cases). The default
value is 0.
Since v7.9.
The purge thread can be safely disabled (-1) if you’re running Connect2id
server 7.9 or newer and have no pre-existing subject sessions in the store.
sessionStore.internal.subjectIndexPurgeInterval=-1
sessionStore.sessionMap.expirationInterval
Overrides the default wake-up interval of the Infinispan thread for expiring
subject sessions which max lifetime was reached. The default value is 300000
milliseconds, or 5 minutes. Zero (0) disables the expiration thread.
This configuration can only be set or overridden via a Java system property.
Since v7.9.
To increase the interval to one hour:
-DsessionStore.sessionMap.expirationInterval=3600000
To disable the Infinispan expiration thread when all sessions are stored in AWS DynamoDB and also automatically expired there via a “ttl” attribute:
-DsessionStore.sessionMap.expirationInterval=0
