JASIG CAS: single sign out not working

Question

I have single sign on working beautifully, but single sign-out is not working.

The scenario is like this:

1. Open webapp1 and get redirected to CAS login page

Answer 1

I've had basically the same configuration for my application before I switched to the spring configuration. I had a look on the SVN and basically the only difference to your config is the use of the Single Sign Out Listener

listener>
    org.jasig.cas.client.session.SingleSignOutHttpSessionListener

Could this work for you? Of course don't forget to add it on both WebApps if it works.

UPDATE: I found the description of the listener in the docs, and it should do what's missing in your setting
