passport-ldapjs

Passport strategy for authenticating against an LDAP server.

Tested with OpenLDAP server and Windows Server 2013 Active Directory

Install

$ npm install passport-ldapjs

Usage

Configure Strategy

The strategy requires a verify callback which accepts a user profile entry from the directory, and then calls the done callback supplying a user.

var LdapStrategy = require('passport-ldapjs').Strategy;

var opts = {
  server: {
    url: 'ldap://0.0.0.0:1389',
  },
  base: 'OU=Users,OU=Company,DC=company,DC=com',
  search: {
    filter: '(sAMAccountName={{username}})',
    attributes: ['displayName', 'givenName', 'mail', 'title', 'telephoneNumber', 'physiscalDeliveryOfficeName', 'userPrincipalName', 'sAMAccountName'],
    scope: 'sub'
  },
  uidTag: 'cn',
  usernameField: 'email',
  passwordField: 'passwd',
};

passport.use(new LdapStrategy(opts, function(profile, done) {
  User.findOne({email: email}, '-salt -password', function(err, user) {
    if (err) {
      return done(err);
    }

    if (user) {
      return done(null, user);
    } else {
      return done('User not found');
    }
  });
}));

Authenticate Requests

Use passport.authenticate(), specifying the 'ldap' strategy, to authenticate requests.

For example, as route middleware in an Express application:

// Create route
app.post('/login', passport.authenticate('ldap', {
  successReturnToOrRedirect: '/',
  failureRedirect: '/login',
  failureFlash: true
}));
