Overview
This page describes how to setup DNS for Samba 4 on Fedora Core 10. It assumes that Samba is already installed in INSTALL_DIR (e.g. /usr/local/samba). DNS can be installed either on the same machine as Samba or on a separate machine.

Installation
% yum install bind

Configuration
[edit]
Configuring Domain Zone
Copy zone data file generated by Samba:
% cp $INSTALL_DIR/example.com.zone /var/named/dynamic
Edit zone data file /var/named/dynamic/example.com.zone:
$ORIGIN example.com.
$TTL 1W
@ IN SOA example.com. root.example.com. (
01 ; serial
2D ; refresh
4H ; retry
6W ; expiry
1W ) ; minimum
IN NS ns1
ns1 IN A 192.168.1.100
samba1 IN A 192.168.1.101
gc._msdcs IN CNAME samba1
27f515e4-f5af-4396-bc93-130013076ab7._msdcs IN CNAME samba1

Configuring Reverse Mapping
Create reverse mapping file /var/named/192.168.1.rev:
$ORIGIN 1.168.192.in-addr.arpa.
$TTL 1W
@ IN SOA example.com. root.example.com. (
01 ; serial
2D ; refresh
4H ; retry
6W ; expiry
1W ) ; minimum
IN NS ns1.example.com.
100 IN PTR ns1.example.com.
101 IN PTR samba1.example.com.
[edit]
Configuring File Ownership
Set file ownership:
% chown named.named /var/named/dynamic/example.com.zone % chown named.named /var/named/192.168.1.rev
Copy zone configuration file:
% cp $INSTALL_DIR/named.conf /etc/named-samba.conf % chown named.named /etc/named-samba.conf
[edit]
Configuring DNS
Edit /etc/named.conf:
options {
#listen-on port 53 { 127.0.0.1; };
#listen-on-v6 port 53 { ::1; };
#allow-query { localhost; };
...
};
include "/etc/named-samba.conf";
Edit /etc/named-samba.conf:
zone "example.com." IN {
type master;
file "/var/named/dynamic/example.com.zone";
};
zone "1.168.192.in-addr.arpa." IN {
type master;
file "192.168.1.rev";
};
Restart DNS:
% service named restart
[edit]
Multiple Samba Instances
The DNS can to be configured such that it points to multiple Samba instances for failover.
$ORIGIN example.com.

Verification
Execute the following commands to verify DNS:
% dig _kerberos.example.com TXT @localhost ... ;; ANSWER SECTION: _kerberos.example.com. 604800 IN TXT "EXAMPLE.COM" ...
% dig _ldap._tcp.dc._msdcs.example.com SRV @localhost ... ;; ANSWER SECTION: _ldap._tcp.dc._msdcs.example.com. 604800 IN SRV 0 100 389 samba2.example.com. _ldap._tcp.dc._msdcs.example.com. 604800 IN SRV 0 100 389 samba1.example.com. ...
