> Hello Everyone,
>
> My name is Varrian Hall. I am in great need of MSChapv2 assistance.
> Presently, my authenticator calculation(20 octets made into 40 hex digits:
> "S=40 hex digits") does not equal the 40 Hex digit(excluding "S=")
> response. I have written my code based on RFC2759. My
> GenerateAuthenticatorResponse( ) function is where the problem lies.
> Again, it's based on the GenerateAuthenticatorResponse( ) function in
> RFC2759. I'm thinking it must be a new update, because some of the code
> in GenerateAuthenticatorResponse( ) is used elsewhere and it is working
> fine. The SHA.. functions are in ChallengeHash and it works fine. The
> MD4.. functions are in NTPasswordHash, and it works fine. My problem is
> in the last SHA_Final function call in GenerateAuthenticatorResponse( )
> that produces the 20 octet result. This result(expanded to 40 octets)
> never matches the result sent to me from a Win2K pc.
> These results have to match in order for the server/client to be
> authenticated.
> Could you please help [Varrian Hall] . Any newsgroups or websites you
> know of would be greatly appreciated.
