Hi,

But the authoritative server IS authoritative for that zone. What that
means is that if a record does not exist in the zone DB or backend, a
NXDOMAIN will be returned. It will never recurse because it KNOWS that
the item does not exist. That is what authoritative means. You may
want to try querying the recursor first and have it return any needed
private records using Lua and then get the rest from your authoritative
server.
