Bing9 PTR Zone error : multiple RRs of singleton type

[Jordan Pittier]

Hi
With Designate V2, a user should be able to change the PTR of his own floating IPs. This feature doesn"t work with bind9 at the moment.

Designate generates the following zone file :

------------------------------------------------------------------------------------------------------------------------------
root@devstack-15h-55m17-09-14:/var/log# cat /opt/stack/data/designate/bind9/4.24.172.in-addr.arpa._484147f6-644a-43ce-9b3f-cbeb8202d7a7.zone
$ORIGIN 4.24.172.in-addr.arpa.
$TTL 3600

4.24.172.in-addr.arpa. IN SOA ns1.devstack.org. email.example.io. (
    1410969503 ; serial
    3600 ; refresh
    600 ; retry
    86400 ; expire
    3600 ; minimum
)

4.24.172.in-addr.arpa. IN NS ns1.devstack.org.

4.24.172.in-addr.arpa. IN SOA ns1.devstack.org. email.example.io. 1410969503 3600 600 86400 3600
4.24.172.in-addr.arpa. IN NS ns1.devstack.org.
3.4.24.172.in-addr.arpa. IN PTR toto.lol.com.
------------------------------------------------------------------------------------------------------------------------------

As you can see there are 2 SOA and 2 NS records. This is problematic with Bind9. Bind9 complains with

Sep 17 15:58:22 XX named[3155]: zone 4.24.172.in-addr.arpa/IN: loading from master file /opt/stack/data/designate/bind9/4.24.172.in-addr.arpa._484147f6-644a-43ce-9b3f-cbeb8202d7a7.zone failed: multiple RRs of singleton type
Sep 17 15:58:22XX named[3155]: zone 4.24.172.in-addr.arpa/IN: not loaded due to errors.

If I edit manually the zone file and remove the duplicate entries, everything work as expected.

According to this doc : http://www.brandonhutchinson.com/multiple_RRs_of_singleon_type.html the duplicates entries are an error.

I am facing this bug with the floating IP API, ie I make curl call to /v2/reverse/floatingips

    Backends need to implement c/u/d_recordset

    The current code means the central generate SOA/NS records are
    not provisioned, nor or any records create via the V2 API.
