When my session expires, I get redirected to /users/login. I should probably get redirected to /users/extlogin instead.

I see where it's theoretically supposed to happen in app/controllers/concerns/foreman/controller/session.rb, but get_sso_method is returning nil, so it never calls the SSO provider's expiration_url and uses the default instead.

Configured using the instructions in the manual.
