      I can confirm they work on 4.6.7. I do recall they have worked for
several prior versions as well. I can't seem to get PTR records to
register though.

The refused request doesn't necessarily mean it's not working. Windows
will send an un-secure request first, followed by a secure request if


You are right with that, I was looking at the first unauthenticated
attempt. Still, the 2nd authenticated attempt fails. Wireshark reports
"Server failure" in this case, and Samba log as follows:

Any ideas?


What you posted was a response to a IPv6 request (AAAA) record. What type of record are you attempting to register?
