what is missing in CNTLMAuthObject

[Srinivas M]

Hello,

I am developing VC application (ATL), that communicates with web service, with NTLM authentication.

following is the code sinppet i have,

Auth Object derived from IAuthInfo to supply user,passwd information.
However, i receive HTTP 1.1 401 (Unauthorized access). error....
Service pservice;
AuthObj auth;

USES_CONVERSION;

CNTLMAuthObject authNTLM;

pservice.SetUrl(_T("http://localhost/contactsweb/service.asmx"));

authNTLM.SetAuthInfo(&auth);

CAtlHttpClient & httpClient = pservice.m_socket;

httpClient.AddAuthObj(_T("NTLM"), &authNTLM , &auth);

pservice.CleanupClient();

bool val = httpClient.NegotiateAuth(true);

CComBSTR hello;

HRESULT hr = pservice.HelloWorld(&hello);

Can anyone point what is that i am doing wrong here?

Did anyone try similar thing, is there any problem with CNTLMAuthObject itself?

What are te other libraries available to use ?

Thanks in adance

Srinivas.
