Python using Ldap Module

Here's an Ldap class using Ldap module.
Installing Python-LDAP requires only one commnad:

$ sudo apt-get install python-ldap


#!/usr/bin/python

import ldap

               # privileged directory access.

               # you will still bind to the server but with limited privileges.
