[Samba] Question about DNS Ghost Records

[Gerhard Stein]

nope, it didn't help:

gerstrong at ZController:~$ /usr/local/samba/bin/samba-tool dns add 
zcontroller calcdom.local Z37 A IP -k yes
ERROR(runtime): uncaught exception - (-1073741811, 'Unexpected 
information received')
   File 
"/usr/local/samba/lib/python2.7/site-packages/samba/netcmd/__init__.py", 
line 175, in _run
     return self.run(*args, **kwargs)
   File 
"/usr/local/samba/lib/python2.7/site-packages/samba/netcmd/dns.py", line 
1053, in run
     0, server, zone, name, add_rec_buf, None)
gerstrong at ZController:~$ /usr/local/samba/bin/samba-tool dns delete 
zcontroller calcdom.local Z37 A IP -k yes
ERROR: Record does not exist

Regards
