I know that we can allow Firefox to allow passing through of Windows credentials by editing the following about:config settings
--If using Kerberos-- network.negotiate-auth.trusted-uris network.negotiate-auth.delegation-uris --If using NTLM-- network.automatic-ntlm-auth.trusted-uris
and in Chrome by adding a command line switch
However, these are both difficult to manage in a company wide setting. Does anyone have any good solutions to this problem?
