Windows servers are pickier about NTLMv2 than Samba.
This enables more secure mounts to Windows (not just Samba)
ie when "sec=ntlmv2" is specified on the mount.

NTLMv2 authentication (stronger authentication than default NTLM) which
many servers support now works.  There was a problem with the construction
of the security blob in the older code.  Currently requires
	/proc/fs/cifs/Experimental to be set to 2
and
	/proc/fs/cifs/SecurityFlags to be set to 0x4004 (to require using
	NTLMv2 instead of default of NTLM)

Next we will check signing to make sure optional NTLMv2 packet signing also
works.
