IMHO the aim to mimic the AD behavior of W2Kx would suggest to use a
location which matches the W2Kx DNS servers, so I suggest to modify the
location used by the new DNS server to
CN=MicrosoftDNS,DC=DomainDnsZones. Anyway in the source4/dns_server
directory I've found only one reference to CN=System path in dns_utils.c:122
