Javascript to create the type1, type3 messages you need to communicate with an ntlm server. I used this to talk to a NTLM enabled windows server from a node.js application.

ntlm.js

var url = require('url');
var crypto = require('crypto');

/*
 NTLM PROCESS FOR GET REQUESTS:
 ==============================

 STEP 1: The Client requests a protected resource from the server
 STEP 2: The Server responds with a 401 status, with a header indicating that the client must authenticate
 STEP 3: The Client resubmits the request with an Authorization header containing a Base-64 encoded Type 1 message.  From this point forward, the connection is kept open; closing the connection requires reauthentication of subsequent requests.
 STEP 4: The Server replies with a 401 status containing a Base-64 encoded Type 2 message in the WWW-Authenticate header
 STEP 5: The Client responds to the Type 2 message by resubmitting the request with an Authorization header containing a Base-64 encoded Type 3 message
 STEP 6: Finally, the Server validates the responses in the client's Type 3 message and allows access to the resource.

 NTLM PROCESS FOR POST REQUESTS:
 ===============================

 STEP 1: The Client submit an empty POST request with a Type 1 message in the "Authorization" header
 STEP 2: The Server replies with a 401 status containing a Base-64 encoded Type 2 message in the WWW-Authenticate header
 STEP 3: The Client resubmits the POST with a Base-64 encoded Type 3 message Type 3 message, sending the data payload with the request.

Hi andypols,
Would you please give me an example how to do it?

Thanks,
