Stack trace dor gssapi-with-mic

[Ted Creedon]

I think there are two problems:
1. geronimo.creedon.biz reverse dnslookups as a comcast uri (its on a
comcast dhcp line) - the forward dns is set up using dyndns. Look at the
garbled klist below..
2. all the servers are suse's - 10.0 thru 11.1 see the previous or I can
update all to 11.1..
