[Samba] Zone update denied

[Peter Pollock]

I'm not quite sure how to ask this question because I don't really know
what's going on, but I'm seeing an error I don't understand.

It appears that when updating the sone record, something is not working
right, but I'm not use what it is

The logs have an error like this:   client @0x7f7bd4089880
192.168.7.144#57386: update 'internal.kcs/IN' denied

It is then followed by Samba_dlz allowing the update of various records
from that IP address, followed by another error which is for the same IP
and is similar but slightly different, like this, for example:

  client @0x7f7be408d970 192.168.7.144#59545: update 'internal.kcs/IN'
denied

This happens 5+ times for each IP address.

Could someone smarter than me (that's all of you) tell me what's going on
and if I should be concerned?

Here's a more complete section from the log:
