Ah, I was mostly waiting for the documentation on the LDAP storage
format of the DNS data.

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.  I agree that the contents represent SOA information, but it does not appear to be in the format of a MS-DNSP DNS_RPC_RECORD_SOA structure.  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?"
