Hi All,

I have a query regarding the interaction between Samba, LDAP and vampire.

The situation is as follows. I have five NT4 servers serving 1000 users 700 of 
which have 4-digit numeric logins. I have a Samba PDC that I'd like to 
transfer all the accounts and data to, Vampire being the obvious method.

I can't transfer the logins to POSIX accounts due to the numeric uid/gid 
system used by Linux so I elected to use OpenLDAP. I am now at the stage 
where I have an LDAP server running and have created all of the NT domain 
groups in the LDAP directory.

I have successfully created numeric id accounts in LDAP and an attempt to 
Vampire the accounts from the old NT4 PDC to the Samba PDC resulted in all 
the users appearing in directory_administrator but no Samba logins working as 
the XP clients reported that the accounts didn't exist on the server. Running 
pdbedit -Lw showed only about 5 accounts so I'm guessing there's a problem 
somewhere along the lines.

My question is therefore, is Vampire going to work in a situation where POSIX 
accounts can't be created as part of the migration process and if not, can I 
migrate the client accounts and SIDS from the old PDC to the new one in order 
to save having to log all of the clients onto the new PDC again.
