Samba4 storage of RID pool?

[Gémes Géza]

Hi,

Is there any function/method, to retrieve the RID pool from a given 
Samba4 (or Win) Active Directory Controller?

I'm asking that because I plan to write a patch for samba-tool which 
would assign uid/gid numbers based on the existing RID, according to the 
following algorithm:
First search for uidNumber==RID and gidNumber==RID, if none found assign 
uidNumber=RID or gidNumber=RID, if the given uidNumber/gidNumber has 
been found (it is already allocated) try the next one from the RID pool, 
until found on free (by free I mean neither uidNumber or gidNumber uses 
that RID).
This way the ability to assign a free uidNumber to groups is guaranteed, 
because the real uidNumbers and gidNumbers don't overlap.

Thank you in advance!

Cheers
