So, why don’t you do that? As far as I know, Domain Controllers still only 
maintain SRV records, so the “underscore zones” approach should still work. 
Make _tcp.example.com, _udp.example.com, _msdcs.example.com, etc. separate 
subzones, with Dynamic Updates allowed (for the Domain Controllers to 
add/delete/refresh their SRV records), and have the main zone (example.com) 
maintained by FusionDirectory. No need to get fancy with LDAP backends…

Subject: Dynamic zone vs static records 





Hello, 





We are managing our DNS zone within LDAP through a 3rd party editor 
(FusionDirectory). This software is configured to export the LDAP configuration 
to plain text zone files, updated on the master (and a zone reload is made by 
the software by calling rndc). 





If we make this zone dynamic we have a serial issue because each server (Acitve 
Directory) dynamically updating the zone increments the serial which do not 
update the LDAP. Refreshing the zone via FusionDirectory do not work as the 
generated serial is lower. 





We are aware that we should not mix the plain text configuration with these 
dynamic records (and use a subdomain instead). As we want to edit the zone in 
LDAP and we would like to make the AD servers autoregister their record in the 
zone, would using bind with the LDAP backend allow us to do so ? 
(FusionDirectory can be configured as a simple LDAP editor without pushing text 
config). 





Let me know if my question is odd or lacking of information. 





Thank you for your further advices.
