ldapjs - write after end error

I have created an authentication service using the following code in Node.js and ldapjs. 

var when = require ('when');
var AuthenticationError = require('../errors/AuthenticationError');
var SessionManagerService = require('./SessionManagerService');

var ldap = require('ldapjs');

var client = ldap.createClient({
    url: 'ldaps://ad.mycompany.com:636',
    tlsOptions: {'rejectUnauthorized': false}
});

module.exports = {

    signIn: function (email, password) {
        return this.ldapBind(email, password).then(
            function () {
                return SessionManagerService.createSessionHash({email: email});
            }
        );
    },

    ldapBind: function (email, password) {
        var deferred = when.defer();
        client.bind(email, password, function(err) {
            if (err) {
                deferred.reject (new AuthenticationError('Invalid username and/or password!', 'Authentication.signIn.error'));
            } else {
                client.unbind();
                deferred.resolve(true);
            }
        });
        return deferred.promise;
    },

};

When I authenticate my user for the first time, it works perfectly but it fails starting from the second attempt. The error message is: 'write after end'.

When I restart the node server it works again for the first attempt.

It looks like something is hanging but I don't know what. Any idea?

I solved this problem a few days ago for creating ldap-client every time in ldapBind function (in your case).
