[Unbound-users] unbound refuses to respons non-recursive queries

[刘明星：）]

send a non-recursive query to an unbound recursor and get a response with rcode REFUSED while whithout RA set. 
lthis is the following
query:
      dig +norecurse tianya.cn @unbound.recurse.ns
response:

   ; <<>> DiG 9.7.2-P2 <<>> +norecurse tianya.cn
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: REFUSED, id: 47807
;; flags: qr; QUERY: 0, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0

;; Query time: 0 msec
;; SERVER: 127.0.0.1#53(127.0.0.1)
;; WHEN: Thu May 19 11:39:58 2011
;; MSG SIZE  rcvd: 12
 
I want to know why unbound does refuse to resonse and why it does not set ra bit.

regards
