[Samba] Sync Unix passwords when not PDC

[joshuajunk at cybertrails.com]

I need to be able to sync the unix passwords on our Samba server. The Samba 
server is running as a file share on a W2k Domain. It is a mixed mode 
domain and I have been able to get the authentification working for the 
file/printer shares. I have been looking into this and the only information 
I can find seems to have to do with "unix sync = yes" however I don't think 
that this is going to work for me since this server is not the PDC.
I'm running Samba on RH 7.2 if it is important.

Thanks in advance,
Joshua
