I am using the CAS module to authenticate my users. That is working fine and dandy, but I want CAS to be the only way a user can authenticate. Currently when the user goes to /login, it shows a page where it gives them the redirection notification message, a drupal login invitation message, and a log in button. Only when they click the login button, is CAS authentication conducted. Is there a way to have it so that the only way to authenticate would be using CAS?
I do not know the CAS module but I do know a very generic way to hide / replace any page with another: add an alias! De-aliasing happens before routing. So if CAS has a page say
/cas you'd like to see when someone visits
/user/login simply add an alias with a system path of
cas and alias
