[Samba] Error update ddnc with static ips and samba 4.4.5

[Trenta sis]

Hi,

With samba 4.4.5 with bind DLZ we have detected an error message with
machines that has static ip

Oct  8 16:52:47 server named[4247]: samba_dlz: starting transaction on zone
domain.com
Oct  8 16:52:47 server named[4247]: client 172.22.187.193#55746: update '
domain.com/IN' denied

Oct  8 16:52:47 server named[4247]: samba_dlz: cancelling transaction on
zone domain.com

We have detected that machines with dhcp (It was configured as is described
in samba wiki dhcp and samba 4) are updating correclty and any message with
error is reported, only with static ips

I have found some messages win samba list  describing this error after a
samba upgrade, and suggest recreate inverse zone, but our environment is a
new environment with 4.4.5, migrated from samba 3

Where is the problem?
