[Samba] RSAT DNS

[Christian Naumer]

Hi everyone,
we are running Samba version 4.19.3 on Rocky Linux 8.9. Recently we have 
been getting errors when using the RSAT DNS Administration tool in Windows.
Two (of 10) of the reverse zones can not be displayed. The following 
error is shown:

"The DNS server has detected an error when loading the zone. The zone 
data may not be available in Active Directory or the zone data may be 
corrupted."

This is translated from German so might be slightly different in the 
original English.

Querying the two zones works fine. I can even list all entries with 
samba-tool:

samba-tool dns query dc1 0.168.192.in-addr.arpa @ ALL -P

In LDAP I can also query and browse all the entries. Dynamic updates 
also work for both zones.

So everything works except using the Windows administration tool.

I suspect it has something to do with the upgrade to 4.19.

Anybody seen something like this before?

Regards

Christian
