Configuring SSO

After analyzing JOSSO and CAS as candidates for SSO , the JOSSO implementation seems very promising.
What is SSO ?

Josso
-----

Positives
--------------------
1) Just works. Can easily embed my application to the SSO framework.
2) Out-of-the box seem less integration with custom made tomcat. Inbuilt SSL configurations.
3) To-Do steps
i) Download Josso tomcat
ii) Refer to http://www.josso.org/tomcat55-howto.html
iii) JAVA_OPTS=-Djava.security.auth.login.config=..\conf\jaas.conf (Spent a romantic night for this. Had to write it )
iv) For getting the login data from the DB refer to this


Negatives
--------------------
1) Pathetic Docs
2) In-active community.

CAS
---
I could not get CAS working on my system. I know it works, but somehow the jigsaw is not complete. The community is very active and vibrant.Updated wiki . Let me know if anyone gets it working.
