ntlm-ad-client

A simple NTLM Client to negotiate and authenticate against an Active Directory.

ntlm-ad-client is heavily inspired by PyAuthenNTLM2. Also a thanks to Alessandro Mancini for separating and refactoring the main part of this module from its originating repository express-ntlm

$ npm install ntlm-ad-client

example usage

const ntlm_client = require('ntlm-ad-client')

const MESSAGE_NTLM_1 = 'MESSAGE_NTLM_1';
const MESSAGE_NTLM_3 = 'MESSAGE_NTLM_3'
const HOSTNAME = 'YOUR_HOSTNAME'
const PORT = 'YOUR_PORT'
const DOMAIN = 'YOUR_DOMAIN'

const client = ntlm_client({
    hostname: HOSTNAME,
    port: PORT,
    domain: DOMAIN,
    path: null,
    use_tls: false,
    tls_options: undefined
})

client.negotiate(MESSAGE_NTLM_1, (err, challenge) => {
    if (err) throw new Error(err);
    console.log(challenge);

    client.authenticate(MESSAGE_NTLM_3, (err, result) => {
	if (err) throw new Error(err);
	console.log(result); // // {"DomainName":"MYDOMAIN","UserName":"MYUSER","Workstation":"MYWORKSTATION"}
