Top open source single sign on app

Question

We're using a webapps like google apps(mail), jira, etc. and would like to implement single sign on on our system. What is the best or top pick when choosing a single sign on app? Is CAS(http://www.jasig.org/cas) a good choice? BTW most of our machines are Ubuntu.

Answer 2

I've used CAS in the past and found it to be excellent for medium sized organisations (<500 employees). It integrates well with Java applications (through Spring Security) and is a very lightweight solution.

An alternative for a much, much bigger approach is OpenSSO developed by Sun. This is a total beast, but meets every conceivable requirement for an SSO policy.
