Authenticate against an LDAP server

Fork of node-ldapauth - A simple node.js lib to authenticate against an LDAP server.

This fork was originally created and published because of an urgent need to get newer version of ldapjs in use to passport-ldapauth since the newer version supported passing tlsOptions to the TLS module. Since then a lot of issues from the original module (#2, #3, #8, #10, #11, #12, #13) have been fixed, and new features have been added as well.

Multiple ldapjs client options have been made available.

var LdapAuth = require('ldapauth-fork');
var options = {
    url: 'ldaps://',
var auth = new LdapAuth(options);
auth.authenticate(username, password, function(err, user) { ... });
auth.close(function(err) { ... })
npm install ldapauth-fork
