I read that page -- but I'm not seeing anything that makes me think my dns
strategy is inappropriate ...
The article does describe the possible deployment strategies in what I
believe to be an overly constrained manner:
>From the wiki:
You can use either the internal DNS server that is built into the samba4
binary, or an external bind DNS server. Default is to use the internal
server, and it is highly recommended that when you start using Samba4 as
AD-DC for the first time, you install it this way. You can later switch
between the two variants if needed. If you do use an external bind DNS
server, it must use the DLZ backend and run on the Samba AD DC.
In my opinion this should be augmented to explain that its simple to use
the internal samba dns in combination with an external dns server.
You can use the samba internal dns in combination with any other dns server
so long as that external dns server resolves queries for your active
directory domain via the samba dns server.
For example, suppose you've configured a samba domain to use the internal
dns as like this:
# *samba-tool domain provision --use-rfc2307 --interactive*
Realm [SAMDOM.EXAMPLE.COM]: *SAMDOM.EXAMPLE.COM <http://SAMDOM.EXAMPLE.COM>*
Domain [SAMDOM]: *SAMDOM*
The above configures samba with and sets the internal samba-dns as the
authoritative dns server for samdom.example.com. To ensure clients find
the necessary active directory information for samdom.example.com, ensure
the dns server on your network resolves all queries for samdom.example.com
via the samba internal dns server.
For example to configure a dnsmasq server to resolve queries for
samdom.example.com via the samba internal dns server -- include in your
where 192.168.1.2 in the above is the ip address of the server running
This third strategy uses the samba internal dns for all dns behavior that
samba/ad depends on, while still allowing use of another dns server than.
The source of truth for samdom.example.com is the samba-dns which is
tightly (and correctly) integrated with the semantics of the active
directory domain. This setup does not require use of BIND and does not
require clients on the network use the samba dns for name resolution.
