Connect2id server 13.7

This Connect2id server release introduces two new configuration properties and fixes a bug affecting DPoP.

New configuration properties

op.idToken.includeX5C -- this configuration makes it possible to control the inclusion of X.509 certificate (chains) in the JWT header of issued ID tokens. The X.509 certificate get automatically included by the Connect2id server when one is found in the configured signing keys. To disable this behaviour and issue leaner ID tokens set this configuration property to false.


op.reg.allowNonTLSLogoutURIsForTest -- the configuration allows the registration of OpenID relying parties as clients with a frontchannel_logout_uri or backchannel_logout_uri that is an insecure (plain) HTTP URL. This is intended to help with test and devops deployments that cannot issue HTTPS certificates. Unsecured logout URLs must not be used in production!


You can find more information about the frontchannel_logout_uri and backchannel_logout_uri parameters in their respective specifications:

Bug fixes

This release fixes a bug that affected DPoP access tokens. If you have a Connect2id server deployments that issues identifier-based access tokens with DPoP and are using the stateless server mode you should upgrade to this version. Deployments that issue JWT-encoded access tokens or use a replication cluster or Redis are not affected.
