Can samba mitigate the vulnerability of NT hashes?

[David Collier-Brown]

Slashdot was all a-twitter about Mark Gamache's tutorial on breaking
NTLM hashes (see
http://markgamache.blogspot.com/2013/01/ntlm-challenge-response-is-100-broken.html)

I know we have long supported NTLMv2, but does the protocol allow a
Samba server to convince a client to *only* use NTLMv2, the version that
is not susceptible to this particular attack?

If so that would be A Kind Thing to do for the community...
