Hi ngtrongtri,

How are you integrating Alfresco to CAS ? In older versions of Alfresco it used to be done by changing web.xml and adding some classes to Alfresco but right now I don't think this is the preferred or recommended way.

You are supposed to install Apache HTTP as a front-end for Apache Tomcat and use the CAS authentication module for Apache and enable external authentication in Alfresco. I've done it a couple of times for different customers and it works right this way. The old way also worked of course, at least for old Alfresco versions, but I think the new way (using apache HTTP) is better documented <a href="http://wiki.alfresco.com/wiki/Alfresco_With_mod_auth_cas">in the Wiki</a> and cleaner.
