LDAP authentication library for Node.JS

node-ldapauth's Introduction

This library is only for LDAP authentication. If you're looking for a more complete LDAP implementation, check out http://ldapjs.org/

LDAP Authentication for Node.JS

Provides a simple function for validating username/password credentials on an LDAP server.

This can be used in web-applications that authenticate users from a central directory.

It binds to the native OpenLDAP library (libldap) and calls ldap_simple_bind().

Building

./build.sh

Usage

Ensure libldap (OpenLDAP client library) is installed.

You need to add ldapauth.node to your application.

var ldapauth = require('./ldapauth'); // path to ldapauth.node

ldapauth.authenticate('scheme', 'some.host', 389 /*port*/, 'someuser', 'somepassword', 
  function(err, result) {
    if (err) {
      print('Error');
    } else {
      print('Credentials valid = ' + result); // true or false
    }
  });

node-ldapauth's Issues

invalid ELF header

while running my app I got:

Error: /vendor/ldapauth.node: invalid ELF header

Aborting on failure to bind

If right attribute data is given, it works without any errors and stays put:
$ ./example.js
Auth: true

But, if wrong attributes are given, it fails as expected, but aborts with the following trace.
Any idea what is going on?
$ ./example.js
Auth: false

node-gyp update needed

New nodejs uses node-gyp instead of node-waf (currently node-waf is used in this project). Could you update installation scripts to use node-gyp .

Support ldapi authentication

Support authentication against LDAP servers on a UNIX socket

Extending node-ldapauth to support authing differently

Would it be possible for node-ldapauth to do authentication on attributes on a users ldap record for example their email address and use another account to do the intial bind with like mod_authz_ldap for apache?

authentication works but search crashes

Note: this is on 1686 machine. I did build the module on the machine.

node version: v0.3.2-pre

When I run the example script, with my credentials and server info, it authenticates fine but then crashes with the following on a search....

node example.js

Auth: true

How to bind the dn in the authentication

Hi Joe,

how can i use the bind dn and password to authenticate on the Openldap server. I was used the java code and that was working fine but here i am not able to find the binddn enteries to be passed to the authenticate function. Any help would be a great help for me...
