samba - Oct 2017 - bind9 and isc-dhcp-Server for dynamic DNS-updates Error

Hello Rolawnd, I followed the wikipage exactly. Bind9 is installed on the Samba
DC.
The Linux-Client should be a member of the Active Directory-domain?

Regards

Have you followed the wikipage exactly, or have you changed anything ?
Is Bind9 installed on the Samba DC ?

Try rebooting the DC and see if this helps, I can assure you it works,
it has done for me for the last 5 years.

It works for printers and I haven't yet found a way to join them to a
domain ;-)

It should work like a normal DHCP server, but it should also update the
Samba AD records.

Two things, can you post your named.conf files and can you find this
line in the /etc/dhcp/bin/dhcp-dyndns.sh :

#NSUPDFLAGS="-d"

remove the comment sign '#' and try again.

You should get a lot more info in the logs.

This is my named.conf
options {
                directory "/var/cache/bind";
                notify no;
                empty-zones-enable no;
                auth-nxdomain yes;
                listen-on-v6 { none; };
                forwarders { 192.168.10.3; 10.0.0.3; };
                allow-query { 127.0.0.1/32; 192.168.16.0/24; };
                allow-recursion { 127.0.0.1/32; 192.168.16.0/24; };
                tkey-gssapi-keytab
"/usr/local/samba/private/dns.keytab";
};

I remove the comment sign '#'
NSUPDFLAGS="-d"

But the logs are the same:
