[Pdns-users] Powerdns Problem with Delegation to Isilon.

Greetings.
We are in the process of migrating from Bind to Powerdns on one of our
compute cluster.
Issue we are having is related to DNS Delegation for Isilon (Related to
Isilon Smart Connect feature.)

Server is Master for .hpc 
we need to delegate for isilon.hpc

In order to achive that we have 

isilon.hpc -> NS isilon-dns.hpc
isilon-dns.hpc -> A record with Ip address.

This works like a Charm in Bind on one of the old servers and doesn't work
in PowerDNS.

Any suggestion on what we might be missing and what might have to be
enabled, or troubleshooting steps would be appreciated.

This is result of DIG command on the old server.
