[Pdns-users] Wrongly sets the Authoritative Answer flag?

[Stephane Bortzmeyer]

I'm starting to experiment with PowerDNS on the '.fr' zone. I see that
PowerDNS sets the Authoritative Answer flag for queries about NS
records which are not in '.fr' but in a child zone:

; <<>> DiG 9.2.1 <<>> @fr-powerdns.dnsexp ns cfdt.fr.
...
;; flags: qr aa rd; QUERY: 1, ANSWER: 2, AUTHORITY: 0, ADDITIONAL: 1
...
;; ANSWER SECTION:
cfdt.fr.                345600  IN      NS      proof.rain.fr.
cfdt.fr.                345600  IN      NS      relay.globalintranet.net.

I believe that PowerDNS is wrong. The server is authoritative for
'.fr', not for '.enst.fr'. nsd and BIND9 do not set the AA flag.
