[Samba] Dynamic DNS updates from Windows 10 workstations

Hi folks,

I just finished setting up a secondary AD DC using Louis' packages 
(thanks a lot Louis) on Debian Buster. No real problems or serious 
headaches there, DNS, DNS replication, Sysvol replication all working. 
Both DCs use the Samba internal DNS server.

I noticed that there are many extremely old and stale DNS A records for 
Windows 10 workstations getting their IP addresses from a dnsmasq DHCP 
server (just using the DHCP part, not DNS). On all workstations, 
registration of the IPv4 address with DNS is enabled. It's absolutely 
plain that no DNS records are updated. How can I get the dynamic update 
in the DNS servers working?

Best regards,
