[Samba] samba-tool dns serverinfo command throws error

[James Atwell]

Hello,

      I'm using the internal DNS server and when running the command 
'samba-tool dns serverinfo dc1 -U administrator' I get the following output.

@dc1:~# samba-tool dns serverinfo dc1.domain.local -U administrator
Password for [DOMAIN\administrator]:
   dwVersion                   : 0xece0205
   fBootMethod                 : DNS_BOOT_METHOD_DIRECTORY
   fAdminConfigured            : FALSE
   fAllowUpdate                : TRUE
   fDsAvailable                : TRUE
   pszServerName               : DC1.domain.local
   pszDsContainer              : 
CN=MicrosoftDNS,DC=DomainDnsZones,DC=domain,DC=local

I'm not experiencing any DNS issues so I believe this may be a bug with 
the move to python3 Am I correct?

Ubuntu 16.04, samba 4.10.3.

Thanks.
