For informational purposes, those who want to know PowerDNS and are 
using BIND8/9, could read this: 
http://laurent.bachelier.name/2009/03/switching-from-bind-to-powerdns-in-a-few-seconds/

If you want to try PowerDNS with LDAP backend, there is a script bundled 
in PowerDNS called zone2ldap which works very nice (read: 
http://www.linuxnetworks.de/doc/index.php/PowerDNS_LDAP_Backend/Migration). 
Use *simple style* (tree style is practically incompatible with IPv6 and 
doesn't allow subdomain/subzone delegation) as explained here: 
http://www.linuxnetworks.de/doc/index.php/PowerDNS_LDAP_Backend/Example.

Migration from standard BIND9 (text files) to PowerDNS LDAP, even for 
testing, is much faster and easier than one might thought.

I can help with implementation details from my experience for anyone 
interested, but, unfortunately, I am not a developer to be able to 
engage in development. So, developers (or funding...) wanted! :-)
