The builtin users/groups use the RID for the GID/UID.

Do you have to go back and add these values to the buildin groups/users
like "Domain Admins"?

You are saying this exact string is the same no matter what?   What's it
used for then?

Quite alot of this stuff isn't standard, nor documented.  It is incredibly
frustrating to deploy Samba 4 in a mixed windows/*nix envir.
