Login with only kerberos as idp (environment variable) seems broken

Open TheBroTMv2 opened this issue 3 years ago • 0 comments

Steps to reproduce

  1. Install Nextcloud
  2. Install user_saml and chose environment variable
  3. try to enter REOTE_USER

Expected behaviour

Tell us what should happen It should take the variable and use it to enable login against kerberos

Actual behaviour

Tell us what happens instead kerberos authorizes the login, user_saml seems to not catch the value of REMOTE_USER and prints an empty Error page (Nextcloud Errorpage but only Error as Error message In the error log i can see that kerberos grants the login and in the nextcloudlog i get an error when Nextcloud tries to get the token
