If you're looking to authenticate a user DN and password, this might be a decent starting point:

var ldap = require('ldapjs');

function authDN(dn, password, cb) {
  var client = ldap.createClient({url: 'ldap://YOUR_SERVER:PORT'});

  client.bind(dn, password, function (err) {
    client.unbind();
    cb(err === null, err);
  });
}


function output(res, err) {
  if (res) {
    console.log('success');
  } else {
    console.log('failure');
  }
}

// should print "success"
authDN('cn=user', 'goodpasswd', output);
// should print "failure"
authDN('cn=user', 'badpasswd', output);

@pfmooney can you please help me with the code line cb(err === null, err); What does it mean I am very new to node.js

@mvgadagi Its calling the cb function which is passed in as the third argument.
err === null will evaluate to either true or false if 'err' is set or not, then is passes 'err' as the actual error.

hello everyone,
i have the same topic to do but am a little bit confused.
This program will be on a .js file and we should link it with a html file to get the data( username and password), isn't it ?
thank you for you answer.
if you have a complete example i would be pleased to try it.
Thank you again.

@srikanth9010 looks like the client is timing out when trying to connect to the server. You could set the connectTimeout option to try to wait longer before failing.
