NTLM Test Server

A comprehensive Node.js server with NTLM authentication for testing NTLM clients like ThunderClient, Postman, and curl.

Features

• ✅ NTLM authentication with predefined test credentials
• 🔍 Detailed step-by-step authentication logging
• 🛡️ Credential validation with test users
• 🌐 Multiple test endpoints (protected and public)
• 🏥 Health check endpoint (no authentication required)
• 🔧 Enhanced error handling and debugging
• 🌍 CORS enabled for cross-origin requests
• 📊 Comprehensive API responses with user information

Installation

npm install

Usage

Start the server

npm start

Start with auto-reload (development)

npm run dev

The server will start on http://localhost:3000

Test Credentials

The server includes the following test credentials for authentication:

Username	Password	Domain	Status
testuser	testpass	TESTDOMAIN	✅ Active
admin	password123	TESTDOMAIN	✅ Active
john.doe	secret456	TESTDOMAIN	✅ Active
alice	alice123	TESTDOMAIN	✅ Active

Note: These are test credentials only. The server validates these credentials during NTLM authentication.

Endpoints

Public Endpoints (No Authentication Required)

• GET /health - Health check endpoint, returns server status

Protected Endpoints (Require NTLM Authentication)

• GET / - Root endpoint, returns user info after successful authentication

Manual Setup

1. Set up NTLM Authentication:

   • Open ThunderClient in VS Code
   • Create a new request
   • Set URL to http://localhost:3000
   • Go to "Auth" tab
   • Select "NTLM" as authentication type
   • Enter credentials (e.g., testuser / testpass)
   • Set domain to TESTDOMAIN

2. Test the endpoints:

   GET http://localhost:3000/health      (No auth required)
   GET http://localhost:3000/            (Requires NTLM auth)
   

Testing with curl

Basic NTLM Test

# This will show the NTLM handshake steps
curl -v --ntlm -u testuser:testpass http://localhost:3000/
