Hi everyone,

With samba 4.9, "samba_dnsupdate --verbose --use-samba-tool" generate spurious error WERR_DNS_ERROR_RECORD_ALREADY_EXISTS (which is true), but it's appear as an error. In older version, it was not giving this error out.

I get this error message both for internal DNS server and Bind DLZ (which I think is logic, since it is using samba-tool...)
