NTLM authentication using node.js

Question

I need to use node.js to communicate with a server using NTLM proxy authentication.

I have used 2 modules:

1. node-curl https://github.com/jiangmiao/node-curl
2. request, coming highly recommended htps://github.com/mikeal/request

I found no documentation for the request module for ntlm , and though node-curl supports the curl easy options , I found no documentation about how to specify the CURLAUTH_NTLM for the CURLOPT_HTTPAUTH.

I want to know how to take care of the NTLM proxy authentication. I would love to continue using the request module.

Answer 1

Wrote a Node.js library to do the HTTP NTLM Handshaking: https://github.com/SamDecrock/node-http-ntlm

It's ported from the python-ntlm library.

Answer 2

If you are using Express you can use express-ntlm it makes NTLM a lot less frustrating overall

https://www.npmjs.com/package/express-ntlm

Answer 3

Is it important for you to use NTLM directly in node.js code?

Instead you can try to install some intermediate NTLM proxies that will give you a chance to use simple HTTP proxy in node.js. There are at least two solutions for it:

1. Cntlm - written in C
2. Ntlmaps - written in Python
