Hi,
I installed my first Samba 4.12 AD with packages from
https://www.sernet.de/ on CentOS 8. Everything seems to work OK,
including DNS records being created for members that join the domain.
Reading https://wiki.samba.org I came across
https://wiki.samba.org/index.php/Testing_Dynamic_DNS_Updates. When I
execute "samba_dnsupdate --verbose --all-names" on the DC I'm seeing the
same errors Daniel Betschart reported on this list on 2020-04-06:
[root at dc01 ~]# samba_dnsupdate --all-names --fail-immediately
; TSIG error with server: tsig verify failure
[root at dc01 ~]# samba_dnsupdate --all-names --fail-immediately
--use-samba-tool
ERROR(runtime): uncaught exception - (9711,

Rowland Penny explained that this could be ignored because Daniel
Betschart joined a Windows DC, but I'm getting these errors on a Linux
DC. I don't seem to have a real DNS update problem, because I have
[2020/05/12 14:46:38.288004, 3]
../../source4/dsdb/dns/dns_update.c:111(dnsupdate_spnupdate_done)
samba_runcmd_io_handler: Child /usr/sbin/samba_dnsupdate exited 0

../../source4/dsdb/dns/dns_update.c:88(dnsupdate_nameupdate_done)
Completed DNS update check OK
in /var/log/samba/log.samba for the automatic updates. Still I would
like to have the error above explained. Please tell me which
configuration details you need.
Thanks a lot
Matthias
