[Samba] Samba Internal DNS not forwarding some zones

[Ralf Spenneberg]

Hi,

I have a Samba 4.17 running as AD with two DCs. I configured a zone in 
the internal DNS service with a few entries. Later I decided to drop the 
zone in samba again and do the configuration on the forwarder DNS.
Unfortunately samba does not forward any request for this zone. The zone 
is deleted.
samba-tool dns zonelist does not show the zone.
ldbsearch -H 
/var/lib/samba/private/sam.ldb.d/DC\=DOMAINDNSZONES\,DC\=AD\,DC\=OCHTRUP\,DC\=DE.ldb 
only shows deleted entries

But still. Anything for xyz.net is forwarded but myzone.net is not 
forwarded to the forwarder. Samba apparently still thinks it is 
responsible for the zone.

Unfortunately I do not get the logging to work.
I tried
log level = 0 dns:10
followed by a
smbcontrol smbd reload-config
But no logs show up. Is there any kind of caching involved? What can I 
do to further troubleshoot? Any ideas?

Kind regards,
Ralf
