I can't find anything relating to my question.  Do you have at least the
subject of the thread?  Is there a way to search these archives?  I'm going
to http://lists.samba.org/pipermail/samba/ but don't see any option of
searching through these archives.  I know I'm overlooking something.

Anyway any suggestions much appreciated.  Thanks!

you are talking about a very sensitive topic...take a look at the postings
between T.Allen and A.Bartlett (around 02/07/20).

To my knowledge, no.

No. 

We just migrated a NT4.0 PDC to samba and it gave us a considerable amount
of pain. You can dump the user/passwords with pwdump and you can extract
the group memberships with rpcclient, at least we did. 

You can fetch the Domain SID and give it to the samba PDC. But you will
run into trouble with the user RID migration, because Samba calculates the
RID out of the Linux UID. So there is no clean way to get the same user
SID from Samba as the user had before on the NT PDC. And not to mention
the trust account passwords...mymy.

I have heard the only reasonable painless way for a migration is Samba
with the LDAP backend, so that you are able to massage the RIDs and trust
account passwords into the directory. But a really transparent NT-Samba
migration is another story.
