Node JS LDAP Auth User

Question

I am creating a login authentication page, where a user would input there active directory username and password and using NodeJS I would check to see if it's valid, but I keep getting

[Error: LDAP Error Bad search filter]

or

[Error: Search returned != 1 results]

When I'm trying to search for the username and password, my code is below:

I'm using: https://github.com/jeremycx/node-LDAP, let's say that the user entered a username of hhill

    var ldap = require('LDAP');
    var ldapServer = new ldap({ uri: 'ldap://batman.lan', version: 3});

    ldapServer.open(function(error) {
        if(error) {
           throw new Error('Cant not connect');
        } else {
            console.log('---- connected to ldap ----');

            username = '(cn='+username+')';
            ldapServer.findandbind({
                base: 'ou=users,ou=compton,dc=batman,dc=lan',
                filter: username,
                password: password
            }, function(error, data) {
                if(error){
                    console.log(error);
                } else {
                    console.log('---- verified user ----');
                }
            });
        }
    });

Does anyone have any suggestions on what I'm doing wrong?

UPDATE

Here is the solution I came up with if anyone ever needs it, with the help of the answer below

    var username = request.param('username');
    var password = request.param('password');

    var ldap = require('ldapjs');
    ldap.Attribute.settings.guid_format = ldap.GUID_FORMAT_B;
    var client = ldap.createClient({
          url: 'ldap://batman.com/cn='+username+', ou=users, ou=compton, dc=batman, dc=com',
          timeout: 5000,
          connectTimeout: 10000
    });
    var opts = {
      filter: '(&(objectclass=user)(samaccountname='+username+'))',
      scope: 'sub',
      attributes: ['objectGUID']
    };

    console.log('--- going to try to connect user ---');

    try {
        client.bind(username, password, function (error) {
            if(error){
                console.log(error.message);
                client.unbind(function(error) {if(error){console.log(error.message);} else{console.log('client disconnected');}});
            } else {
                console.log('connected');
                client.search('ou=users, ou=compton, dc=batman, dc=com', opts, function(error, search) {
                    console.log('Searching.....');

                    search.on('searchEntry', function(entry) {
                        if(entry.object){
                            console.log('entry: %j ' + JSON.stringify(entry.object));
                        }
                    });

                    search.on('error', function(error) {
                        console.error('error: ' + error.message);
                    });

                    client.unbind(function(error) {if(error){console.log(error.message);} else{console.log('client disconnected');}});
                });
            }
        });
    } catch(error){
        console.log(error);
        client.unbind(function(error) {if(error){console.log(error.message);} else{console.log('client disconnected');}});
    }

In this case, you need ldapClient rather than ldapServer, this is the example code from the official doc:

var ldap = require('ldapjs');

ldap.Attribute.settings.guid_format = ldap.GUID_FORMAT_B;

var client = ldap.createClient({
  url: 'ldap://127.0.0.1/CN=test,OU=Development,DC=Home'
});

var opts = {
  filter: '(objectclass=user)',
  scope: 'sub',
  attributes: ['objectGUID']
};

client.bind('username', 'password', function (err) {
  client.search('CN=test,OU=Development,DC=Home', opts, function (err, search) {
    search.on('searchEntry', function (entry) {
      var user = entry.object;
      console.log(user.objectGUID);
    });
  });
});
