Samba 3.0.21 & NTLMSSP with NTLMv2

[Jet Info]

Hi, Andrew & Samba Team!   
   
I read the archive of samba-technical posted on May 17 00:06:40 GMT 2003 (link  
http://lists.samba.org/archive/samba-technical/2003-May/029542.html) and I have  
same problem:  
If I configure my Domain to "use NTLMv2 only, refuse LM&NTLM" and configure samba  
to use NTLMv2 (client NTLMv2 auth = Yes client lanman auth = No), I can  
successfully connect to a samba share.  
But if I also configure XP client  
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\MSV1_0]  
"NtlmMinClientSec"=dword:00080000 - "Minimum session security for NTLMSSP based  
(including secure RPC) clients - require NTLMv2 session security. I got 'the  
network request is not supported.' at the XP client  
Does new Samba version support NTLMv2 in NTLMSSP? 
If not, Is it planned to include this option in future?
