[Building Sakai] CAS login with local login

[Charles Hedrick]

Actually, the existing code seems to be set up to do this. It keeps a session property indicating whether CAS has been consulted. The first time it calls CAS. If that fails, it calls the normal login screen. I didn't see how that would work because my tests with CAS were in the normal login mode where it either returns with the user logged in or doesn't return. Can you tell me how to call CAS in this mode?

Wouldn't it be easier just to check the cookies to see if there's a CAS cookie present? Or is the cookie not accessible to Sakai?

Or is the point just to make sure that you can receive users who are already logged in because of a portal or something like that? Can you point me at instructions on how to set this up? It sounds like that might be a good starting point for us.
