With a BIND resolver you get an authoritative answer from the resolver
the *first* time this resolver receives an answer directly from the
authoritative server (presumably because this answer is *not* from the
resolver cache). For the second and later answers, you don't get an
authoritative answer (because the answer comes from the resolver's
cache).

PowerDNS recursor gives you a non-authoritative answer even if it has
just received this answer from the authoritative server. IMHO this is
just as correct as the BIND behavior.

Personally I find the BIND behavior moderately confusing, and the
PowerDNS recursor behavior less surprising.
