Hi Farzan,

Shibboleth can be complex, yes, with much to learn about it and many
opportunities to configure.

The CAS-Shibboleth bridging piece isn't too bad.  Here's my favorite
solution:

I thought this presentation was pretty good:

Hope that helps,

I watched this presentation and read about the shib-cas-authenticator. Neat stuff!

I have already configured Shibboleth IdP v2.3.8 to use CAS authentication as described here:

  https://wiki.jasig.org/display/CASUM/Shibboleth-CAS+Integration

(Install the CAS Client for Java, configure IdP to use the RemoteUser LoginHandler).

After seeing your presentation, I commented out the PreviousSession LoginHandler in handler.xml, thinking that all requests to the IdP would go back to CAS. My goal was to have just a single SSO session rather than CAS + Shibboleth SSO sessions.

However, it appears that the CAS Client for Java in the IdP is keeping the session "alive". Even if I logout of CAS, I am not redirected to CAS for a new ST the next time use the IdP. I assume the CAS Client for Java is storing my authenticated state in the Jsession.

Any thoughts on this? Would setting useSession=false on the CAS Validation Filter work? Can the CAS and Shibboleth sessions be bridged without using the shib-cas-authenticator?

Thanks,
        Andy
