ldap authentication strategy for Passport

An Example to use ldap-authentication as a Passport Strategy

This example uses ldap-authtication to create a Passport LDAP authentication strategy.

Installation

1. npm install

Work flow

1. node index.js to start the server
2. Launch browser and goto http://localhost:4000
3. Login as prompted
4. Try different username and password

How does it work

This example uses ldap-authtication and put it in passport-custom to create a complete Passport strategy.

The LDAP server is hosted at forumsys and it has a few simple users to test with.

The information of the LDAP server is saved in config.js file.

ldap-authtication takes the username and password from the submitted form, with the ldap configurations from config.js file, it then constructs an option object:

const CONFIG = require('./config.js')
// ...
let ldapBaseDn = CONFIG.ldap.dn
let options = {
  ldapOpts: {
    url: CONFIG.ldap.url
  },
  userDn: `uid=${req.body.username},${ldapBaseDn}`,
  userPassword: req.body.password,
  userSearchBase: ldapBaseDn,
  usernameAttribute: 'uid'
}

then it calls let user = await authenticate(options) to authenticate and retrieve user from the LDAP server.

I encourage you to check the index.js file for details. Clone this repo and play with it yourself!
