LDAP Authentication for Node.JS

Provides a simple function for validating username/password credentials, and group membership 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(), then searches with a base of the groups parameter and a filter of "(member=)".

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('some.host', 389 /*port*/, 'someuser', 'somepassword', 'ou=SomeGroup,o=GROUPS', 5 /*timeout in seconds*/
  function(err, result) {
    if (err) {
      print('Error');
    } else {
      print('Credentials valid = ' + result); // true or false
    }
  });
