I agree; So, please post your comment in that thread too! If you think 
of anything that would help (by finding developer(s) or funding for) the 
project, please give your feedback. Note that the LDAP backend will not 
be removed from v3.0, but -if left umaintained- it will not include any 
improvements whatsoever. I am doing what I can to avoid this.

I have recently provided (enough, I hope) evidence that the LDAP backend 
should remain alive and kicking for many reasons.

I assume that you don't have any public networks, because with strict 
mode you can't have AXFR for reverse zones.

In fact, it's not a workaround/tip. It's a different approach, which I 
believe is better. If you want/need more technical details for the 
implementation I suggested, I can provide, although it's 
straightforward. The problem in your case - if you follow this plan - is 
probably that you would have to modify practically all your RRs (but it 
will only be needed once and you'll never need to mess-up with DNS 
server configuration for sortlist etc.).

Even included in unmaintained status, I have come to believe that the 
whole project may be harmed.

The project's developers should comment on it. You should file a ticket 
here for your request: http://wiki.powerdns.com/trac/ - mention that you 
want this for the LDAP backend. I don't know if this would be a 
backend-specific implementation or it can be done at the main software 
level.

All the best,
Nick
