Doesn't look lame to me. It answers queries for tirparkolo.dipmap.com as
well as for ns/ns1/ns2.dipmap.com. Only the NS record is wrong.

My Unbound resolver (current svn) keeps returing the correct answer.

Shouldn't it fail with "harden-referral-path" set? Or is it enough if
the child servers sends answers for the nameserver names from the parent
zone even if the NS records differ?

Here's a query trace from unbound-host w/ harden-referral-path:
