Hallo,
during upgrade from 32.0.6 to 32.0.12 I encountered the problem with the user_saml app and the joinscript of nextcloud failing:
The difference is, that my system was already upgraded to UCS 5.2.6 and keycloak (not simplesamlphp!).
I fixed the join, but still have problems with existing ldap-users logging in to nextcloud. LDAP-setup seems basically Okay. I see existing and new users and groups in nextcloud. But only new users can login.
In the nextcloud-log I see the error message: “RuntimeException HMAC does not match.”
I have googled and tried to fix a lot, but did not find a solution.
Has someone an idea for me, how to fix that issue?
Best regards
