You're trying to obtain a service ticket for imap/hermod, but the TGT you're attempting to use is not accepted by the KDC. If you klist after running imtest, you have no imap/hermod ticket. I've never seen an error like that. It suggests that you KDC is really broken :) Something like the key used to encrypt your TGT isn't valid for obtaining service tickets. :wes ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
