You keep accusing me of censorship, like developing a DLZ is military work!
Feels childish at this point. Would be counter productive to keep it up.

Oh yes, let's spill the state secrets.
Here is the answer I get from NS2, which provides data from the DLZ:
/ # dig A test.com -p 153 @127.0.0.1
; <<>> DiG 9.18.9 <<>> A test.com -p 153 @127.0.0.1

I can see "AUTHORITY: 0" in the answer, and now I understand NS1 does not cache
this because of that (did not know only authority 1 answers are cached when I
sent the initial email. How did you expect me to ask the question in the first
place? Is that documented somewhere btw?)
My question still stands: shouldn't NS2 answer with AUTHORITY: 1, regardless of
DLZ or local-file backend, since the definition for the zone is as below?
dlz XDB {
database "dlopen /usr/lib/bind/dlz_mongodb_mod.so <MongoDB URI> 0";
search no;
};
zone "test.com" {
type master;
dlz XDB;
allow-query { any; };
};
