[Samba] S4: Linux clients do not have DNS records

samba 4.0.6 DC
Hi
Linux clients joined to the domain do not have dns entries on the DC but 
still work OK. Here is a query for a machine called pinoso:

samba-tool dns query hh16 hh3.site pinoso A
Password for [Administrator at HH3.SITE]:
ERROR(runtime): uncaught exception - (9714, 
'WERR_DNS_ERROR_NAME_DOES_NOT_EXIST')
   File 
"/usr/local/samba/lib64/python2.7/site-packages/samba/netcmd/__init__.py", 
line 175, in _run
     return self.run(*args, **kwargs)
   File 
"/usr/local/samba/lib64/python2.7/site-packages/samba/netcmd/dns.py", 
line 974, in run

If we change the dns of the client, it still works just fine although 
the DC seems to have no record for it. Worrying. . .

Should Linux clients have dns records on the DC? I can't see how they 
would work if they don't. Are they stored elsewhere?
Thanks,
Steve
