Authentication via Jasig CAS / Single Sign-on

Jasig offers the Central Authentication Service (CAS) project that provides single sign-on services. Our university uses this project to provide authentication to a number of our online services; however, we have had to resort to LDAP authentication for Percussion CM System / Rhythmyx. We would like to see the option to authenticate through CAS. We have invested time into implementing CAS through JAAS; however, we have not been successful.

Update: Working solution has been proposed.
