MSCHAPv2 is encryption compatible with NTLM, not NTLMv2.  (It simply
changes how the 8-byte LM challenge is prepared, and removes the LM

The client cannot (while sending a valid MSCHAPv2 response) us the
NTLMv2 crypto.

However, if as I suspect the issue regards the policy settings which
appear to allow MSCHAPv2 from a windows RADIUS server, but not a Samba
ntlm_auth/winbind server, to a domain allowing only NTLMv2
authentication, then I remain stumped.  See my mail earlier today.
