I worked with a commercial client trying to find a way to make this
work, and despite quite some effort (trying to behave the same way the
Mac SMB server does, or even investigating having some agent on the OD
server) didn't make any useful progress, even to having a protocol. 

And that assumed some pretty privileged access to OD, which you don't
have. 

Essentially this was lost when we killed security=server, which isn't
compatible with NTLMv2 and isn't compatible with any form of session
signing (now pretty much required, at least at negotiation). 

Of course, you can still use Kerberos, that just requires you get a
keytab and set up DNS properly etc.

Sorry!
