Use ldapjs with bluebird promise

I posted something similar here: Use ldapjs with promise. Unfortunately, it is still unsolved.

This time I tried bluebird and hopefully I can get some luck.

// https://www.npmjs.com/package/ldapjs
var Promise = require('bluebird');
var ldap = Promise.promisifyAll( require('ldapjs') );
var config  = require('./config');
var print_r = require('print_r').print_r;


var my_filter = "(&(objectCategory=person)(objectClass=user)" + "(cn=" + 'someone' + "))";
var ldap_username = config.ad.username;
var ldap_password = config.ad.password;
var ldap_url = config.ad.url;
var ldap_dn_search = config.ad.dn_search;

process.env.NODE_TLS_REJECT_UNAUTHORIZED = "0";
ldap.Attribute.settings.guid_format = ldap.GUID_FORMAT_B;


var opts = {
  filter: my_filter,
  scope: 'sub',
};


//test
console.log(my_filter);
console.log(ldap_username);
console.log(ldap_password);
console.log(ldap_url);
console.log(ldap_dn_search);


/* NOTE: This code is working!!!
client.bind(ldap_username, ldap_password, function (err) {
  client.search(ldap_dn_search, opts, function (err, search) {
    search.on('searchEntry', function (entry) {
      var user = entry.object;
      console.log(user);
    });
  });  
});
*/

// I tried to rewrite the code above with promise
ldap.createClientAsync({
  url: ldap_url
})
.then(function(client){
  console.log('bind'); // No print
  return client.bindAsync(ldap_username, ldap_password);
})
.then(function() {
  console.log('search'); // No print
  return client.searchAsync(ldap_dn_search, opts);
})
.then(function(search) {
    // No flow here
  search.on('searchEntry', function (entry) {
    var user = entry.object;
    console.log(user);
  });
})

The script doesn't output anything. It is waiting for something in terminal.

Using Bluebird Promises, the easy way to do this is to create your client normally, and then run the promisifyAll() on the client.

var ldap = require('ldapjs');
var Promise = require('bluebird');

var client = ldap.createClient({
  url: 'ldap://my-server:1234',
});

Promise.promisifyAll(client);

Now you can call client.addAsync() and client.searchAsync() and such.

client.bindAsync(secUserDn, secUserPassword)
  .then(doSearch) // if it works, call doSearch
  .catch(function (err) { // if bind fails, handle it
    console.error('Error on bind', err)
  });

function doSearch(data) {
  client.searchAsync('CN=A Test,OU=Users,DC=website,DC=com', options)
    .then(function (data) { // Handle the search result processing
      console.log('I got a result');
    })  
    .catch(function (err) { // Catch potential errors and handle them
      console.error('Error on search', err);
    });
}
