Mike,

Try this from the Official Samba How-To

http://www.samba.org/samba/docs/man/Samba-HOWTO-Collection/groupmapping.html

In the section in the section, "Default Users, Groups, and Relative
Identifiers". The only three _required_  groups are: 
  Domain Admins, RID=512
  Domain Users, RID=513
  Domain Guests, RID=514

In addition to these groups I also have the following domain users just
for completeness: 
  Domain Administrator, RID=500
  Domain Guest, RID=501


The builtin groups (RIDS=544 through 533) are not listed as required,
but you can put them in your ldapsam backend. You will have to add them
with, sambaGroupType=4, if you want them to show up in usermgr.exe.

If I have got the correct understanding, SIDs that start with S-1-2-21
will be domain SIDs and will be followed by the domain sid and then a
RID. The SIDs that start with S-1-2-32 are for local SIDs (machine local
users and groups) and should be put in a machine local backend (at least
when I get the time I will look into putting them into a local tdbsam on
the local server).

Unfortunately, as you have found, you have to piece together a lot of
different sources to find the correct working solution for your specific
situation. Although I have a working ldapsam backend I wish I could take
the time and recreate and redo my Samba Domain with the knowledge that I
have gained over the past three plus years (that I have incorporated
LDAP). 

However, I can find the time to try and normalize my old LDIF files and
format them with what I think a "minimal" Samba Domain should contain
and send them to you but these will most likely be specific just to a
Samba3+LDAP domain (I have no intention of going to Samba4 any time
soon).
