Samba/Winbind/nsswitch problem

[Stephen Allen]

I've installed and configured samba with winbind, to allow Windows 
Active Directory users to log in without me having to create a local 
account for them.

Generally speaking, it works (I can login, wbinfo -u|-g returns the 
correct data).  I can login as a Windows user through ssh, and am using 
the pam_mkhomedir module (which also works ok).

Anyway, I've got 2 questions/problems...

(1)
Whenever I restart samba, syslog receives messages like these below.

auth/auth_util.c:create_builtin_administrators(792)
create_builtin_administrators: Failed to create Administrators
auth/auth_util.c:create_builtin_users(758)
create_builtin_users: Failed to create Users
auth/auth_util.c:create_builtin_administrators(792)
create_builtin_administrators: Failed to create Administrators
auth/auth_util.c:create_builtin_users(758)
create_builtin_users: Failed to create Users

(2)
If I use the "winbind enum users|groups = Yes" options, syslog receives 
messages like these below (hundreds of them... every few mins).

nsswitch/winbindd_group.c:winbindd_getgrent(1110)
could not lookup domain group department (maths)
nsswitch/winbindd_group.c:winbindd_getgrent(1110)
could not lookup domain group department (mecheng)


Can anyone help please?

Many thanks,
Steve :)
