[Samba] NetBIOS name for BDC?

[baiocco.f at filottrano.bcc.it]

I have a Samba PDC working fine (NetBios name FI0X07) and I'm trying setting up
a Samba BDC but I can't have it working!!

The problem is:

- if a set the BDC NetBIOS name the same as PDC, if I shut down the PDC the BDC
works but if the PDC is restarted the BDC doesn't stop autenticating users.
- if a set the BDC NetBIOS name different if I stop the PDC the BDC doesn't
authenticate users at all.

This is my PDC smb.conf can someone tell me what I shoud modify to use it for
the BDC??
