Hi, Kai, I worked with the MS-ADTS folks quite a bit and they collaborated with the MS-DNSP devs. From the MS-ADTS devs:
"Microsoft DNS Server can be configured in Active Directory Integration Mode (see http://technet.microsoft.com/en-us/library/cc772746(WS.10).aspx and http://technet.microsoft.com/en-us/library/cc772774(WS.10).aspx). In this mode, zone data is stored in Active Directory, and the attribute called "dnsRecord" is used to store SOA records. These values are opaque to Active Directory. After initial investigation, the format of these records appears to differ from a SOA record as described in MS-DNSP." We will be making an update to MS-DNSP to describe how dnsRecords and "Counted names" appear on-the-wire. I'll keep you updated and I'll see you next week at SNIA.

Ah, great. I'll be at the SNIA conference and then flying over to the Interop Lab as well. I'll be bringing my test environment. Some thoughts on your previous email: > I reviewed the SOA.BIN record you produced.

The fixed part (SerialNo, Refresh, > Retry, Expire and MinimumTtl) line up. And, Primary Server and Zone > Administrator E-mail follow, but not as DNS_RPC_NAMES. The issue is more > than just WORD v DWORD padding. I agree. The SOA record contains two RFC1035 domain-name fields. My request was mainly based on my assumption that the storage of DNS data in LDAP was going to be in the same format as the data sent over the wire in the DNSP protocol. Given that an RFC1035 SOA RDATA record has a different order, the DNSP document looked like a better match. So basically my question boils down to "Where do I find documentation on how DNS data is stored in LDAP?"
