partial log out issue with IDP 2.3.6, SP 2.4.3

[Wang, Holly]

Hi, 

Our current IDP is 2.3.6, and I was told that our SP is 2.4.3. Currently, we have problem with our log out from our Moodle side. Here is the detail:

1. in moodle, we input following configuration:

    *   Shibboleth Service Provider logout handler URL: http://csun.mrooms3.net/Shibboleth.sso/Logout 
    *   Alternative logout return URL: http://www.csun.edu 

2. During the Shibboleth log out process, the session cookie is killed, but can't forward to the return URL by showing up following url, browser displays "Partial Logout" error
http://csun.mrooms3.net/Shibboleth.sso/Logout?return=http%3A%2F%2Fwww.csun.edu 

Brower side: 
Partial Logout
You remain logged into one or more applications accessed during your session. To complete the logout process, please close/exit your browser completely.

3. If I refresh the browser, or replace the special character in URL, the browser will go to the return URL without any problem
http://csun.mrooms3.net/Shibboleth.sso/Logout?return=http://www.csun.edu 


I searched the archive, seems like there was a bug which was fixed by Scott in older version.  I don't know why I still got this error with the new version. Please advice on how can I get it fixed.  

Thanks
