DHCPv6 DDNS update failing "NOTAUTH"

Hi,

 

I am attempting to use DDNS for DHCPv6 clients, and am getting the following message when the client renews a lease.

dhcpdv6[6014]: Unable to add forward map from dhcp-xxx.xxx.xxx.xxx.abc.domain.co.uk to 2001:xxx:xxx:1f02::d42f: NOTAUTH 

 

The DHCPv6 transaction is working absolutely fine, it is just the DDNS bit that's failing to work, which is done by the DHCPv6 server. DHCP/IPv4 works absolutely fine for the same subzone and the same clients. It is the same grid members serving the same clients for both protocols.

 

I can't find any explanation in the admin guide for the meaning of 'NOTAUTH'.

 

Thanks,

 

Andy.

The DHCP server is reporting that it is getting a non-authoritative response for the zone it is attempting to update.

 

Do a "dig abc.domain.co.uk. soa" from the DHCP server and check that the "aa" flag is set.

Hi Paul,

 

This is the answer I get back

 

;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 56818
;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0

 

Infoblox GUI shows the subzone to be Authorative.

 

Thanks,

 

Andy.

Oh hang on, I just remembered, I think it might actually mean NOT AUTHORIZED.

Ok so where would this authorisation be configured, as presumably it's an internal Infoblox process of a DHCP process being able to update the zones? This is something that has always just worked for us, but suddenly stopped in a particular subzone.

 

Thanks,

 

Andy.

Not for the first time, this seems to have just sorted itself out! The zone is now accepting dynamic updates.

 

Thanks for the assistance.
