Log into a DC, run 'samba-tool fsmo show' and look at the line that
starts 'RidAllocationmasterRole'
It should show 'CN=NTDS Settings,CN=LARKIN27'

Try running this on the DC:

ldbsearch -H /usr/local/samba/private/sam.ldb '(objectClass=rIDSet)' dn

Replace the path to 'sam.ldb' with the path to your sam.ldb.

It should should show the DN's of your DCs followed by the contents of
the 'rIDNextRID' attributes. these should be '0' on all DC's except
the RID master.
