[Samba] Samba4 DNS: "recursion requested but not available"

[Michael B. Trausch]

Hello all,

This is with Samba 4.0.0rc6 with the built-in DNS server.  Found the 
problem in Samba 4.0.0rc5 originally, then updated to see if bug had 
been fixed between rc5 and rc6.

I am trying to get mail working for a subdomain that is being managed by 
Samba 4.  I added an MX record, but the problem here is that the Samba 4 
DNS server isn't replying with the record:

=====================================================================
[mbt at aloe ~]$ dig -t MX nautest.naunetcorp.com @s4.nautest.naunetcorp.com

; <<>> DiG 9.9.2-P1-RedHat-9.9.2-5.P1.fc18 <<>> -t MX 
nautest.naunetcorp.com @s4.nautest.naunetcorp.com
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOTIMP, id: 5782
;; flags: qr rd ad; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 1
;; WARNING: recursion requested but not available

;; WHEN: Sat Dec  8 16:21:38 2012
;; MSG SIZE  rcvd: 51
=====================================================================

The query should return the name and priority of the MX server that I 
have defined.  The MX shows up in the "samba-tool dns query" output, so 
it's just the DNS server that isn't responding correctly.

Is this a bug, or is this the result of something I've done wrong?

	Thanks,

	Mike
