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??
