Support Jabber GSSAPI/Kerberos Authentication
GAIM v2.0 (and 1.5 with a patch) supports GSSAPI/Kerberos authentication. There are two open source Jabber servers that support GSSAPI/Kerberos authentication. We use jabberd2+gaim in our office for some single sign on goodness. I would like to use gajim.
The servers that support it are: Jabberd2cvs & Wildfire 3.01
