[Pdns-users] Problem with delegation of reverse subzone

[Barry Kostjens]

Hi All,

Im currently moving from mydns to powerdns. Wrote a converter and 
importet all records into powerdns (using the gmysql backend). I tried 
debian sarge, debian etch (with the stable pdns-server packages) and now 
Im using pdns-static_2.9.21-1_i386.deb. On all versions I have the same 
problem.

Everything works ok, but the lookup of PTR records that are delegated 
fail in powerdns.

These records are present:

192-26.191.35.195.in-addr.arpa 	NS 	a.ns.xillion.nl 	86400

192-26.191.35.195.in-addr.arpa 	NS 	b.ns.xillion.nl 	86400

192-26.191.35.195.in-addr.arpa 	NS 	c.ns.xillion.nl 	86400


201.191.35.195.in-addr.arpa 	CNAME 	201.192-26.191.35.195.in-addr.arpa 
3600 	


Now a query @  dns1 running powerdns:

dig -x 195.35.191.201 PTR @dns1.ilimburg.nl

; <<>> DiG 9.3.4 <<>> -x 195.35.191.201 PTR @dns1.ilimburg.nl
; (1 server found)

While on dns2 (running mydns) it works:

 dig -x 195.35.191.201 PTR @dns2.ilimburg.nl

; <<>> DiG 9.3.4 <<>> -x 195.35.191.201 PTR @dns2.ilimburg.nl

Does anyone have an idea what is going wrong here, and how I can fix it?

Thanks,
