What would cause a keytab to stop working?

[Gedaliah Wolosh <gwolosh@njit.edu>]

I created a keytab back in April for a principal.  I was able to
authenticate successfully using the keytab until a few days ago.  As far
as I know, neither the keytab nor the principal has changed.

The timestamp on the keytab still shows as April 2005, and kadmin shows
that the password for the principal has not changed.

Nevertheless, kinit -t 'keytab' principal yields a "Password incorrect"
error.

Suggestions on where to look??
