I just tested this properly with a 1.3.4 implementation I built for someone else
recently; I was incorrect. The only time that the KDC is not queried is if you
do not have tickets to begin with. If you have valid realm tickets but try to
log in with something like "ssh -l fakename valid.host.com", the KDC will
be queried. I expect this is probably reasonable behavior in both cases.
(The KDC _will_ be queried if you are using PAM to authenticate via Kerberos
with password-interactive, also.)
Sorry to mislead; I tested briefly but didn't actually check to see if I had
tickets before I did so.
