The Basics

  • Nextcloud Server version: 30.0.8 (i think)

  • Operating system : Ubuntu with Cyberpanel

  • Web server : Open lite speed

  • Is this the first time you’ve seen this error? (Yes / No):
    Yes

  • When did this problem seem to first start?
    after removing SSO SAML plugin

Summary of the issue you are facing:

When I login, it gives me an internal server error. If I clear cookies, the login page works just fine. If I try to access a public chat on Talk without being logged in, it works.

Steps to replicate it (hint: details matter!):

  1. Install SSO SAML plugin
  2. Set up SSO SAML (wasn’t working so…)
  3. (so… I) Remove SSO SAML plugin
  4. Internal server error when logged in

I get some of these :

I get a lot of these
"Undefined array key \"sp-name-id-format\" at /home/mydomain.com/public_html/apps/user_saml/lib/Controller/SettingsController.php#73"

I get some of these:
"array_key_exists(): Argument #2 ($array) must be of type array, null given in file '/home/mydomain.com/public_html/apps/user_saml/lib/SAMLSettings.php' line 145"

Hello @messy,

welcome to the Nextcloud community! :handshake:

I’m don’t really get the problem. let me rephrase it a little. You install the plugin, don’t use and remove again - here internal server error happens for login unrelated to SSO? did you try to restart the application after SAML plugin was removed? please share full logs.
