[Pdns-users] Delegation broken?

[Michael Loftis]

Why do I have broken delegation wit the below records.  I was notified of 
this problem by the customer.  PowerDNS should be returning NS records, 
instead it returns SOA for parentdomain.org instead of the three NS for 
sub.paren.org  -- i've changed the actual domains involved in the below 
records but that's it.  Using gmysql backend, mysql 4.1.11 and powerdns 
2.9.19 on Debian Woody (3.0) *and* RedHat 7.3 testing box, both produce the 
same result.

I've tried adding another zone for the sub but I still never get the right 
answer from powerdns, it never responds with authority section pointing out 
the correct servers.

I'm pretty certain this is a pretty nasty bug because I can't delegate 
subdomains at all right now.
