Thank you, Andreas for response.<br><br>I really prefer 1) option. I hate C stuff.<br>I examine VW code for NTLM and It's not really difficult. <br><br>And maybe I can use CurlPlugin for that. It's will be more simple solution for me<br>

You have basically two options:<br>
1) Implement it from scratch. There are a number of resources that describe NTLM in detail (basically reverse-engineered since there's no official documentation), for example:<br>
<br>
<a href="http://www.innovation.ch/personal/ronald/ntlm.html" target="_blank">http://www.innovation.ch/personal/ronald/ntlm.html</a><br>
<br>
2) Implement it via a plugin using the Microsoft SSP interface. Your starting point would be here:<br>
<br>
<a href="http://msdn.microsoft.com/en-us/library/aa375512%28VS.85%29.aspx" target="_blank">http://msdn.microsoft.com/en-us/library/aa375512%28VS.85%29.aspx</a><br>
<br>
FWIW, we went for option #2 in our products; the authentication part is tricky (lots of details) but straightforward in principle (i.e., you basically call InitializeSecurityContext twice and are done).<br>
