[Samba] Samba 4 internal DNS - how to modify SOA record

[Dmitry Khromov]

Hello.
How could one modify a SOA record in rc3? For example, NS part (not NS record) of SOA record points to an absent Windows server. This effectively breaks DNS updates, since there is no such server and if corresponding A record is added, update requests from clients will come unsigned.
Editing it directly via LDAP breaks Samba (some sort of checksum/hash?) MMC snap-in says "Zone not loaded by DNS server", so it is not possible to use it either. samba-tool dns add|delete|update can't operate on SOA record.
Maybe someone could give a link to some document describing dnsRecord, so one could forge a valid record and just change dnsRecord in DC=@ using some LDAP tool?

Thanks in advance.
