I am developing a portal to Liferay and want to apply there a Single Sign On mechanism (SSO). I am using Jasig CAS for centralized authentication of my multiple web applications. Until now I know that I am able to use CAS as an authentication method but the next step would be to add some more intelligence and ask the authentication from an Active Directory server.
This should be possible by using AD as a "database" towards which the authentication is made, but I am new on these things and do not know how to make this with Jasig CAS.
Any clue how to accomplish this task?
