No, that's not //just// like that. You need to
change a few options in order to get the PDC/BDC expected
behaviour.

In fact, filesystem sync and account sync are two
different problems, they are related but not dependent.
You could use vampire or tdbsam or winbind or LDAP to keep
accounts in sync.

No, it is not. You should use a WINS server,
probably on the PDC, and properly use other paramenters
in smb.conf like 'local master' and 'preferred master'.

Did you check the Official Samba HOWTO? Specially
the Domain Control chapter?
http://samba.org/samba/docs/man/Samba-HOWTO-Collection/ServerType.html#id327269

First of all, you should use the right commands
and configuration options (man smb.conf) and you can
use a small network for the BDC, change a workstation
from PDC network to BDC one and see if it works.

Samba needs some care and attention, specially
on special cases like PDC/BDC, the Samba By Example is
also a good read to understad real case scenarios.

This is not exactly a RTFM, but you will need to give
us more information if you really want help, smb.conf, logs
and better subject lines would be a great improvement.
