GDM AD authentication

[Ness, Todd]

I have a SuSE8.1 workstation that authenticates against an AD domain for ssh
logins,
Relevant messages:

If I try to login from GDM I get:

test004
Jun  7 08:49:42 SSPRJDS20TEST gdm[2332]: (pam_krb5) cleanup_state


Does anybody have any clues as where to fix this service module error?
