[Samba] Migrating samba 2.x PDC to new machine and samba 3.x PDC

[Greg Goodrich]

I'm trying to migrate from an older samba 2.x PDC machine into a new 
machine that has samba 3.x and also uses an LDAP backend.  I've heavily 
used the IDEALX.org website and documentation to get the vast majority 
of the work accomplished and working.  I had to modify some scripts that 
were referenced there for migrating posix accounts over to LDAP so that 
they could also handle migrating the smbpasswd file as well.  My users 
work beautifully.  However, the machine accounts are giving me fits.  My 
guess is that the sambaNTPassword entry is getting in the way of 
success.  What I really need to be able to do is turn off the old PDC 
machine, turn on the new one, and have everyone reboot their machines 
and log back into the "new" domain (same domain name as before).  Well, 
whenever I have run a trial run of this, I get the error  that either my 
password is incorrect or my machine doesn't have an account on the 
domain.  If I re-join the domain through windows, it works just fine.  
However, I noticed that my sambaNTPassword hash is different than what 
it was for the same machine account on the old PDC.  I'm not certain how 
this hash is generated for machine accounts.  Assuming that the server 
hostname had some role in this, I changed the new PDC to have the same 
hostname as the old PDC.  Now, I do get a different sambaNTPassword hash 
if I add my machine to the new domain through windows, but it still does 
not match the original hash from the old PDC.  Since the old PDC is 
samba 2.x, I can't use net rpc vampire to migrate the accounts over.  
Does anyone have any idea what other thing(s) I can change to get the 
hash to produce the same way on both servers?  I believe this to be my 
last hurdle in what should be a very nice improvement to our LAN.  TIA
