Re: NTLM Authentication Project

["Loek Maartens" <l.maartens@xxxxxxxxx>]

Hi Thomas,

I do not have any experience with the MS NTLM api, but just found a PDF 
document from MS detailing the HTTP use of NTLM;

I just googled with {NTLMv1, the actual protocol details} and found a very 
details API specification as the second document presented.

Hope to help,

Loek Maartens.
