OK, I will add something to that page :)
Domain Admins needs to own files in Sysvol, Domain Admins is a group and
groups cannot own files on Unix. To counter this, Domain Admins is
mapped to 'ID_TYPE_BOTH' in idmap.ldb, this make it a group and a user.
If you give Domain Admins a gidNumber, it breaks this mapping and it
just becomes a group and, as I said, groups cannot own files on Unix ;-)
I personally create a group called 'Unix Admins', give this group a
gidNumber and make it a member of the 'Administrators' group.
If you use the 'rid' backend, then you do not need to do anything.
