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

About the fork

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.

Usage

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

Install

npm install ldapauth-fork
