How to use the ldapjs.EqualityFilter function in ldapjs

function listUsers(req, res, next) {
	assert([ 2, 3 ].indexOf(keys(req.rdns).length) !== null);
	assert('teleport' === req.rdns.o);
	assert('users' === req.rdns.ou);
	var layer = req.bindLayer;
	assert(layer);
	// If searching for a specific user
	var uid = req.rdns.uid;

  if ( uid ) {
    req.filter = new ldap.AndFilter({
      filters: [req.filter, new ldap.EqualityFilter({attribute: 'uid', value: uid})]
    });
  }
	
  var resultCount = 0;
  
	function end(err) {
		log.info({requestId: req.logId, command: 'listUsers', resultCount: resultCount}, "Sent %d users", resultCount);
    res.end();
		next(err);
	}

	dataStore.layerUsers(layer).on('user', function(user) {
    var attributes = clone(user);
    // Apply some defaults
    if ( !attributes.uid ) attributes.uid = user.uid;
    if ( !attributes.cn ) attributes.cn = user.uid;
