error: PAM: User account has expired for wlin from hongkong.test.org - why?

[Wendy Lin]

Can anyone explain this pam error to me? I have configured a machine
(192.168.2.105) as Kerberos5 client on Suse 12.3 via yast talking to
the kdc at 192.168.2.98 and now get this error on the client if I try
to log in via ssh:
