[Samba] Understanding internal DNS usage on Samba 4

[Marco Gaiarin]

Mandi! Lou via samba
  In chel di` si favelave...

> I'm currently studying migration from Samba 3 to Samba 4 (NT4 to AD).  Using classic upgrade [1].
> Currently (alongside with our Samba 3 PDC), we have a heterogeus environment with external DNS servers:

If you have currently a DNS/DHCP setup, you can leave it as-is; but
effectivaly Active Directory (not samba, but AD!) mandates the use of
DNS, so you have to setup a forward zone for the domanin.

The better choice will be define a subdomain of the current domain,
keeping the examples will be 'ad.example.com', for the AD domain.

In this way, with glue records or dns forwarders, you can have both
world speak each other.


Anyway, AD is merely LDAP+DNS+NTP+Kerberos in Microsoft salsa, so DNS
is a core component in AD domains.
