You seem to be using userinfo and not introspect endpoint in your configuration. Does userinfo return active too?

I get a different error from RC:

Can you provide auth_debug=yes logs?
Turning n debug showed the problem:
Oct 4 14:50:31 mx dovecot[1302421]: auth: Debug: oauth2(christian@roessner.email,192.168.0.4,<3kfgc+MGeuXAqAAE>): oauth2 active_attribute "active" is not present in the oauth2 server's responseIn earlier configuration tests I had an 'active' claim. Dovecot prior 2.3.21 seems to had ignored a missing field, while newer version expect it to be present if configured.
Thanks.

Yes, this was a bug that was fixed, that the active attribute is now actually checked.
I thought I had mistakenly removed the active field, but I did not:
curl -X POST -d 'scope=email&token=****HIDDEN***' https://oauth.authserv.me:4445/admin/oauth2/introspect {"active":true,"scope":"openid profile email groups dovecot offline offline_access","client_id":"718f4a52-e1a8-431d-9146-15809cfe3240","sub":"977c6572-d017-103b-836b-b5fc6e126160","exp":1696442299,"iat":1696438699,"nbf":1696438699,"aud":[],"iss":"https://oauth.authserv.me:4444","token_type":"Bearer","token_use":"access_token"}As you can see, the 'active' field exists, but Dovecot expects it to be a claim, which it is not.
From auth_debug:

I would expect the field shown above.
