yes, my scenario is very simple.
1 server zentyal Domain, and a few XP client in this domain.
When I log into de domain, I can see the shared folders and only access to where I have permissions, but when I open the browser (configured to user the proxy and SSO enabled) it does not work.
I have only 3 rules, 1 users, 1 admins
When I disable SSO, when I open the navigator it ask me for an user / password and it works ok. but when I enable SSO, it does not work, it always shows me an error "access denied to cache"
so, if I see the log file I can see that there is no user name given, so I can assume the proxy does not know who is trying to access, so it denies everything.
