This is a case of sharing code between things in Samba.
The error messages originates normally from
the user token creation where smbd attempts to create the
BUILTIN\Administrators and BUILTIN\Users groups (only
possible if the system is configured to support "winbind
nested groups").  This is to mimic the adding of Domain
Admins to the local Administrators group that happens
on Windows hosts when they join a domain (or when you
run dcpromo to create a domain controller).

nss_wins does not use tokens (or has no need to I should say)
and so really shouldn't be executing that code.  But because
of the the amount of shared code in Samba, you will see
situations like this form time to time.

Bottom line is that you can ignore the message from nss_wins.
I think you have already discussed supported "winbind nested
groups" using the idmap_uid and idmap_gid options.  So I
won't go into that.

Hope this helps to explain things some.
