[Samba] Samba3.0.1pre3 LDAP Login problem

Hi

I read all the HOWTOs I could find on the net about the LDAP PDC and 
still, I can't get it to work.
Here are some infos about the server
Samba version 3.0.1pre3 running Redhat 8.0 with a OpenLDAP server 
version 2.0.27.

I want to do a new domain named DOMAINB from the users I imported from 
DOMAINA (NT4 PDC) using net rpc vampire.
It went well and every user is in the DB, including the machine 
accounts and the groups ( groups mappings too ). I don't know if this 
is right but I changed every SIDs from the original accounts to the new 
server SID (got it from net getlocalsid) please tell me if this is 
wrong.

The problem occurs when I try to join the domain using a Windows 2000 
SP2 client (signorseal=0). I constantly get the message : User / 
Password is wrong from the client.
The root/nobody are also created.

Here are the debug messages I get, starting by the LDAP logs :

daemon: conn=0 fd=9 connection from IP=127.0.0.1:1296 (IP=0.0.0.0:389) 
accepted.

Now goes the SAMBA log :

Here is my samba config file :

I think this is all, thank you for your help and thanks to the samba 
team for writing such a useful software!
