Hi Clint, Your summary is correct. I tried upgrading my home desktop from 11.04 to 11.10 and one of the first things I check when I do this is whether ssh and kerberos are working properly because I often work from home on this computer. I also have a laptop with 11.04 that I have NOT upgraded to 11.10 for comparison. As far as I can tell, kerberos is functioning properly and the errors I posted earlier indicate that my destop (11.10) now cannot communicate the kerberos ticket while ssh'ing via gssapi-with-mic, whereas my laptop (11.04) does communicate the ticket successfully with gssapi-with-mic. I've scoured the files in /username/.ssh/ and in /etc/ssh/ for any discrepant settings and even tried outright replacing such files (not .ssh/known_hosts, of course, but I did try deleting and regenerating it), but nothing produces a different result.
