Yes i think you are right

Why samba use the sambaNextRid field from the
sambaDomainName entry to build the SAMBA SID of the computer accounts ?
in which configuration file SID's creation is different for users and computers
?
Is there a new samba.schema since september month ? (Mine is original
samba.schema with minor update change recommended by whatsnew for 3.0.23)?
Thanks
