Sorry, my mistake.
Looking in the smb.conf of the samba3 file server I forgot to add the
second DC name in the password server entry.
Adding that all works.

Anyway, if I join the samba4 machine to the sbs domain as DC (with the
samba-tool domain join command), the procedure does not create any entry
for the dns stuff (I mean named.conf, named.conf.update and zones files
in the private and private/dns folders).

At this moment I have w2k3 sbs as master dns but in order to remove the
sbs server I have to move bind as master. So, how should I proceed?
Obviously about named.conf* files I have to modify the zones from slave
to master but about ddns? And about dhcp ddns?

Thanks in advance,
Daniele.
