Oh, it doesn't work like either of my ideas! I think I get it now. The
dhcpd service is not involved at all. It does not have to be configured for
ddns. Rather, the windows workstation notifies the samba server, which in
turn runs nsupdate to push the update through bind to the samba ldb files.

My tests showed the NOTAUTH problem. My configuration was all fine, so I
finally ran "samba_dnsupdate" again as suggested in the wiki, and that
fixed it.

If I understand correctly, I should also be able to get reverse records to
update dynamically if I set up a GPO for it. I'll have a look at that next.

Thanks very much for your help,
