Can't login after password change.

[TB]

I had my FC3 Linux box authenticating just fine against my Windows AD
server using kerberos.  Then I changed my password on my Windows XP
machine.  A week later I logged off my Linux box and now I cannot log
back in.  I've tried using the old password, the new password, even the
password for the local account for my user ID.  Root can log in fine.
Any idea what the problem may be??

Thanks.
