For the beginning, try to run this on the *client* machine:
$ kvno imap/fi.example....@fi.example.com
If it works then Kerberos principal itself and client configuration should be
okay and it is necessary to look at server configuration.
If it doesn't work you may try to run it as:
$ KRB5_TRACE=/dev/stdout kvno imap/fi.example....@fi.example.com
$ KRB5_TRACE=/dev/stdout thunderbird
and check debug messages.
- wrong file permissions on keytab file used by server
- wrong SELinux label on the keytab file
- wrong DNS configuration which prevents client from finding server or KDC
(this possibility should be eliminated by kvno command above)
Have a nice day!
