Samba3 only supports queries against AD PDC with the "support for unix" stuff that came in R2, or against a stand-alone Linux Samba3 PDC.
I don't think Samba4 is useful here. To add the UID/GID mappings you
need to extend the AD schema. once you do that (with extra schema
elements that just happen to match the ones in 2003 R2 - ie as if you
were preparing to upgrade to 2003 R2) then you can use the idmap_ad
Or, if you can't do that, then I understand you can share the UID/GID
mappings on a distinct OpenLDAP server.

samba-technical is the right place for Samba4 questions. I don't think
Samba4 is quite what you want here however. you could of course add a
Samba4 DC into the mix, but it would not add value in the area you
