Gitlab CE login screen do not show SAML omniauth provider option
Hi,
After upgrading from 9.2.1 to 9.3.0 the SAML sign in option disappeared from the login screen. We use both github and SAML(ADFS) omniauth providers and the github one is showing just fine. The strange thing is that the /users/auth/saml/callback endpoint is still available and if I forge correctly SAMLRequest I may log in , so I suppose that the problem is cosmetic one, and we just do not see the SAML redirect button on the login screen.
Could you please let me know how to enable more verbose logging so I may see why /users/sign_in HTML do not show SAML button? I tried increase the verbosity via /opt/gitlab/embedded/service/gitlab-rails/config/environments/production.rb log.level but I see no clues why the log-in page do not show SAML button.
Thanks
