That is dated from 2010 and is well outdated ;-)

only if you are using the internal dns server built into your Samba DC. 
If you use Bind9 instead, the 'forwarders go into its conf file.

It doesn't matter if you have 10 clients or 10,000 clients in your AD 
domain, you must use at least one DC as the dns domain server. All Samba 
AD DC's are authoritative for the dns domain (it is known as 
multi-master), so you might as well use them all as nameservers, all the 
dns records are in AD. You need to use a dns server that can update/read 
the AD dns records, the only supported dns servers are the builtin dns 
server and Bind9, dnsmasq is not supported on a DC.

You can use dnsmasq on Unix domain members, but only as a caching 
nameserver, it must use a DC as its nameserver.
