I have been having authentication issue with firefox users. They get prompted for username/password even though they have already been authenticated on the domain. We have two Ironport s360 WSA's deployed for load-balancing/redundancy, running v6.3.3-015. Authentication scheme is set up to use NTLMSSP or Basic. Under the identity set up, I have the scheme as 'Use NTLMSSP'.
One particular Firefox user is using Firefox v3.6. He has entered one WSA redirect hostname into the browser using the 'about:config', 'filter', and 'network.automatic-ntlm-auth.trusted-uris' config options. He cannot enter more than one hostname.
Is there any option I can look at in the Ironport to help these FF users?
