It sounds like your 'main server' is configured as a Samba AD Domain 
Controller (seeing the smb.conf from that computer would confirm this) 
and if so, should be referred to as a DC (it helps, a 'server' could be 
many things)

This sounds like a Unix domain member and the smb.conf you posted a link 
to, confirms this.

Nope, it isn't really referred to as a password server, if it is a DC, 
it is much more than that ;-)

AH, are you used to Samba3 ?

AD doesn't really work like that, well, not without doing other things.

Can you please post the the smb.conf from the other Samba computer.

Why do you need SMBv1 (ntlm auth = yes) ?

Once I have all this info, I will help you to write your smb.conf files 
correctly and help you to get things working.
