Windows Azure Active Directory Passport.js Plug-In

Passport is authentication middleware for Node.js. Passport can be used in any Express-based web application. A comprehensive and large set of strategies support authentication using a username and password, Facebook, Twitter, and more. In order to enable you to quickly integrate Windows Azure Active Directory in to your website quickly, we have developed a strategy for Windows Azure Active Directory.

The passport-azure-ad module is a WS-Federation / SAML-P authentication provider for Passport. This provider lets you integrate your Node app with Windows Azure AD so you can use its many features, including web single sign-on (WebSSO).

The code is based on Henri Bergius's passport-saml library and Matias Woloski's passport-wsfed-saml2 library.

passport-azure-ad has been tested to work with both Windows Azure Active Directory and with Microsoft Active Directory Federation Services.

For a detailed walkthrough of using Passport.js to add web single sign-on to a Node app, see: Windows Azure AD Walkthrough for Node.js.

Installation

$ npm install passport-azure-ad

Usage

This sample uses a WS-Federation protocol with express:

var express = require('express');
var passport = require('passport');
var wsfedsaml2 = require('passport-azure-ad').WsfedStrategy
var app = express();

// configure express
app.use(express.cookieParser());
app.use(express.bodyParser());
app.use(express.session({ secret: 'keyboard cat' }));
app.use(passport.initialize());
app.use(passport.session());
app.use(app.router);

var config = {
	realm: 'http://localhost:3000/',
	identityProviderUrl: 'https://login.windows.net/ad0ffc54-96b9-4757-bbb0-fcc293e2f4aa/wsfed',
	identityMetadata: 'https://login.windows.net/ad0ffc54-96b9-4757-bbb0-fcc293e2f4aa/federationmetadata/2007-06/federationmetadata.xml'
	logoutUrl:'http://localhost:3000/'
};

var wsfedStrategy = new wsfedsaml2(config, function(profile, done) {
    if (!profile.email) {
        done(new Error("No email found"));
        return;
    }
    // validate the user here
    done(null, profile);
});

passport.use(wsfedStrategy);

// implement your user session strategy here
passport.serializeUser(function(user,cb){ ... });
passport.deserializeUser(function(userid,cb){ ... });

// send the user to WAAD to authenticate	
app.get('/login', passport.authenticate('wsfed-saml2', { failureRedirect: '/', failureFlash: true }), function(req, res) {
    res.redirect('/');
});

// callback from WAAD with a token
app.post('/login/callback', passport.authenticate('wsfed-saml2', { failureRedirect: '/', failureFlash: true }), function(req, res) {
    res.redirect('/');
});

app.listen(process.env.PORT || 3000)
