Description

I created an OAuth2/OpenID Connect authentication source to test out authentication with my new Keycloak server. When assigning an Authentication Name I used "keycloak test". This appears to have caused problems with Keycloak because of the space in the name. Changing the space to a dash character in Gitea fixes the error. I would think that url-encoding the space would have fixed the problem as well. Here's the error that I see in Keycloak's log:

03:07:45,157 WARN [org.keycloak.events] (default task-38) type=LOGIN_ERROR, realmId=test, clientId=gitea, userId=null, ipA
ddress=127.0.0.1, error=invalid_redirect_uri, redirect_uri='https://git.example.com/user/oauth2/keycloak test/callback'
