                Thank you so much!!!!!! I was convinced Firefox didn't allow pass-thru authentication and would be stuck with IE :-(...but you proved me wrong!

                Question though, what are network.negotiate-auth.trusted-uris and network.negotiate-auth.allow-non-fqdn for? Configuring the other two let me achieve what I wanted.

                THANKS AGAIN! Keep up the good work!

                Of course using winbind and kerberos authentication. and joined to the domain.
                I for me but I try does not work.
                What am I doing wrong?
