[Samba] How to change SID in ntuser.dat?

[Stefan Drees]

Hello,
i try to migrate user/groups from NT4 PDC to Samba3 with LDAP backend.
There is already an NIS-Server with Samba runing, so there exists two
userlists.
I migrated the user/ groups from windows via net rpc vampire and
added/changed
the UID´s from the NIS-Server but didn´t change the SID.
A teammate told me, there could be some access problems, if i don´t
change the SID.
So i tried to change the SID in ntuser.dat to produce a samba equal SID
(RID = 2xUID +1000).
/usr/bin/profiles dumps me only the reghive, but doesn´t change the SID.
I´m using Samba 3.0.24.

Any hints?

Regards
Stefan D.
