To ensure that Firefox works with Windows on the Share URL with Kerberos SSO, modify the following variables in the about:config special URL:
network.negotiate-auth.delegation-uris network.negotiate-auth.trusted-uris network.negotiate-auth.using-native-gsslib
When using Firefox on Linux, add your server name to network.negotiate-auth.trusted-uris and get a Kerberos ticket using the kinit command:
kinit -f <username>
For example, kinit -f user1, where user1 is an Active Directory user. If the client and the server are on the same machine, go to the external interface. The loopback interface won’t be able to authenticate. View your tickets using klist.
Note: The ticket might correspond to a different user than your Linux user
name.
