Each DC must be authoritative for the AD dns domain and there must be
no other dns server running on the computer, except for Bind9 and this
must be set up correctly.
When you set up Samba (either by provisioning a new domain or by
joining as a DC to an existing Domain), a file should be created in
/var/lib/samba/bind-dns if BIND_DLZ is used. If you add this line to
Then the correct .so should be used.
No matter which of the supported dns server is used (internal or
BIND_DLZ), the dns records are stored in AD, so you can switch between
dns servers by either adding 'server services = -dns' to the DC's
smb.conf (this will use Bind9) or by commenting any 'server services'
line (this will use the internal dns server)
When joining a new DC, /etc/resolv.conf must have an existing DC's
ipaddress as the first nameserver until the new DC is joined. After the
join, the first nameserver must point to its own ipaddress and Samba
