Windows AD Dynamic Updates

Use these configurations to configure BIND to allow dynamic updates from Windows AD servers.

ACL

This makes later config easier, if you have more than one domain controller.

 acl "DOMAIN-CONTROLLERS" {
     10.144.30.101;  // DC1-dave
     10.144.35.2;    // DC2-dave
     10.150.30.5;    // DC-jim
 };

Zone Delcarations

Master Config

 zone "_msdcs.lambnet.us" IN {
     type master;
     file "dynamic/_msdcs.lambnet.us";
     allow-update { DOMAIN-CONTROLLERS; };
 };
 
 zone "_sites.lambnet.us" IN {
     type master;
     file "dynamic/_sites.lambnet.us";
     allow-update { DOMAIN-CONTROLLERS; };

     type master;
     file "dynamic/_tcp.lambnet.us";
     allow-update { DOMAIN-CONTROLLERS; };
 };
 
 zone "_udp.lambnet.us" IN {
     type master;
     file "dynamic/_udp.lambnet.us";
     allow-update { DOMAIN-CONTROLLERS; };
 };

Slave Config

 zone "_msdcs.lambnet.us" IN {
     type slave;
     masters { 10.144.30.4; };
     file "dynamic/_msdcs.lambnet.us";
     allow-update-forwarding { DOMAIN-CONTROLLERS; };
 };
