Sign-in restrictions SSO

Hello,

I’m trying to configure gitlab as a SP to do SSO with our custom ipd. During configuration I disabled the login without SSO (I’m not able to login with username and password, because there is no inputfield anymore).
The SSO is not working right now and I was wondering if I can reset the admin settings somehow from the backend? I use a self-managed Gitlab server.

Hope someone can help

It took me some time to find this… in case someone has the same problem:
open rails console:

gitlab-rails console
ApplicationSetting.last.update_attributes(password_authentication_enabled_for_web: true)
gitlab-rails restart
