Hi @gitwittidbit ,
Your authurl is wrong. Vikunja expects the base URL of the realm (the issuer value of the OIDC metadata), see also the Keycloak example.
The value for you should be https://keycloak-fqdn/realms/realm1. Vikunja will then append /.well-known/openid-configuration and read the other URLs from there. I’ve done several changes to the docs for OpenID recently, I’ll propose another change to the docs and try to clarify a bit better. If you have any other feedback regarding the OIDC config, please let me know
