Thanks for the reply. I can't recall runnning configure.pl. Before I
cause myself any harm, I thought I should check with the list. The
smbldap.conf says to run `net getlocalsid` to obtain the SID for the
config. When I do that I get a different SID from what I was
expecting. I would have expected the domain part of the local machine
SID to match the domains SID but they do not (see below) and I would
have expected the local machine SID to match what is in the

net getdomainsid
SID for local machine PDC is: S-1-5-21-597566789-4152996160-2957772391
SID for domain FOO is: S-1-5-21-1979685110-1467996072-351907979

grep SID /etc/smbldap-tools/smbldap.conf

When I create a new user, the user get a primary group SID that looks like
and a SambaSID that reads:

So I need to change the way the domain part of the primary group SID
is defined and possibly edit the smbldap.conf so that the SID uses the
domain SID. Does that sound correct? If so, how can I modify the
primary group SID?

Thanks again,
