#authenticate!Object

Try to authenticate a user using the CAS ticket passed in params. If the ticket is valid and the model's authenticate_with_cas_ticket method returns a user, then return success. If the ticket is invalid, then either fail (if we're just returning from the CAS server, based on the referrer) or attempt to redirect to the CAS server's login URL.
