samba - Jul 2003 - where Samba stores the SID when acting as PDC?

Hello everyone.

As far I know, all Microsoft domain are identified with
a SID. It is used for authorization, for example in the file
ACLs of the users' files. Before using it, this SID is generated
at random. This SID resides in the PDC,

When Samba is acting as PDC, where lives this SID?
(I suppose that in a file).

I'm asking this because I'm thinking in a backup
procedure for my Samba server and I would like
to backup the SID. If I wouldn't do so, the just
installed Samba will generate a different SID at
random, so there would be problems with the files
with the old SID in the ACLs.

Any help is welcome. Thanks in advance.

There are now commands (particularly in 3.0's net utility) to get and
set that sid, independent of the rest of the secrets.tdb file.
