LDAP js client

node >= 8.0

No ldapjs (https://www.npmjs.com/package/ldapjs) as dependency.

Why: because ldapjs is not maintained for more than two years.

Installation

npm install ldapjs-client

var LdapClient = require('ldapjs-client');
var client = new LdapClient({ url: 'ldap://127.0.0.1:389' });
