[Samba] Using ntlm_auth to authneticate to an NTLMv2 AD

While we're trying to get the tracing for this, I was wondering if there
was another solution we could implement.
Our AD team have put my linux box into its own part of the AD tree i.e.
I don't know anything about AD but was wondering if it were possible to
change the security requirements for the "linux" portion of the tree to
be NTLM. I know this works
Would this be doable?

The problem is that MSCHAPv2 is cryptographically equivalent to NTLM,
not NTLMv2 at the DC end. I suspect there is a flag we need to send to
the DC, to make it ignore it's own policy here.
Any help chasing this down gratefully appreciated: Mostly I need to see
how an MS RADIUS server would achieve the same results, but with 'secure
channel: require signing' set, rather than sealing (it is a local/domain
policy). (This will allow the collection of an ethereal trace between
the RADIUS server and the DC).
