Authenticate against an LDAP server

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

Currently the latest released version of ldapjs which this module depends on does not install succesfully on Node v0.12 on Mac (see issue #258) due to old dtrace-provider dependency. To work around the issue, add dependency to ldapjs master to your package.json:

  "dependencies": {
    "ldapjs": "mcavage/node-ldapjs",
    "ldapauth-fork": "2.3.1"

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://ldap.example.com:636',
var auth = new LdapAuth(options);
auth.authenticate(username, password, function(erruser) { ... });
auth.close(function(err) { ... })
npm install ldapauth-fork
