right, but from a usability point of view it would be nice to have the input fields, where one is entering the username and password, on the content management system side. I don't mean to submit the username and password to the content management system, but as described below would submit it directly to CAS by setting the action attribute accordingly. It might make sense to better understand the reason for the "login ticket". I have been "googling" for some documentation on the "login ticket", but didn't find any useful information. Do you have any pointers about the "login ticket" which are explaining the concept of it?
