samba - Apr 2025 - DNS management error accessing the domain zone

Rowland, when I try to query the dns zone directly from the samba
domain controller (connected over ssh) I obtain this error message:

Got NTLMSSP neg_flags=0x62088215
ERROR(runtime): uncaught exception - (3221422092, 'The stub received bad
data.')
  File "/usr/lib/python3/dist-packages/samba/netcmd/__init__.py", line
279, in _run
    return self.run(*args, **kwargs)
           ^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/usr/lib/python3/dist-packages/samba/netcmd/dns.py", line
1101, in run
    buflen, res = dns_conn.DnssrvEnumRecords2(
                  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/usr/lib/python3/dist-packages/samba/netcmd/dns.py", line 119,
in f
    return attr(*args)
           ^^^^^^^^^^^


The command used to do the query was:
samba-tool dns query -U username localhost example.local @ ALL

Any ideas?

Thanks in advance

You say this domain is old, could it be so old that it was
originally a W2k or W2003 domain ?

Or, to put it another way, do you have dns records in
'_msdcs.example.local' ?
