r14403: * modifies create_local_nt_token() to create a BUILTIN\Administrators
group IFF sid_to_gid(S-1-5-32-544) fails and 'winbind nested groups = yes' * Add a SID domain to the group mapping enumeration passdb call to fix the checks for local and builtin groups. The SID can be NULL if you want the old semantics for internal maintenance. I only updated the tdb group mapping code. * remove any group mapping from the tdb that have a gid of -1 for better consistency with pdb_ldap.c. The fixes the problem with calling add_group_map() in the tdb code for unmapped groups which might have had a record present. * Ensure that we distinguish between groups in the BUILTIN and local machine domains via getgrnam() Other wise BUILTIN\Administrators & SERVER\Administrators would resolve to the same gid. * Doesn't strip the global_sam_name() from groups in the local machine's domain (this is required to work with 'winbind default domain' code) Still todo. * Fix fallback Administrators membership for root and domain Admins if nested groups = no or winbindd is not running * issues with "su - user -c 'groups'" command * There are a few outstanding issues with BUILTIN\Users that Windows apparently tends to assume. I worked around this presently with a manual group mapping but I do not think this is a good solution. So I'll probably add some similar as I did for Administrators. (This used to be commit 612979476aef62e8e8eef632fa6be7d30282bb83)
