samba - Nov 2025 - Join linux-client trixi not working no dns update

Hi!

there seems to be something wrong with your signature. evolution mail
client can't show the content.

anyways, my other client on the phone just ignores it and shows the
content.

As Rowland said, that looks like a problem with the hosts file.
I did run in the same problem a few weeks ago.
The error messages tells that the DNS update fails because the record
already exists. I've spent hours to find the records or the problem in
bind9 and samba ldb. No, it is in the hosts file.

imho this could be a bug. Because even if it's in the hosts file and a
client asks the authoritative server to do an DNS update in its backend
it just should do it and ignore the hosts file or other non-
authoritative sources.
Or if it's not considered as a bug it should be documented somewhere
(in docu of bind_dlz, domain join, ...)

Remove your client entry from the hosts file for now.
You could try to insert the DNS entry with nsupdate -g. That did work
for me too.

I removed the client from AD with "samba-tool computer delete
client01", then I removed the entry line with the clients IP-address from
/etc/hosts. And tried it again. Same shit. I never used "nsupdate"
until now which parameters do I have to give to update the DNS-entry? I usually
use "net ads dns register" I also think it's a bug, or as it
happens more often, bad or non existing documentation. I think I will write a
bugreport
