What We Will Need

---

To test the proxy capabilities of the OpenLDAP server, obviously you need a directory server that actually holds the data and the proxy server that we will play with. I do not suppose that you have two computers to experiment with; therefore, I designed the exercise to be completed with one computer only. Simply run the directory server on a different port than the LDAP proxy server. In our example, we will let the proxy server run on the standard port (389) and the directory server on a different one, e.g., 689. Furthermore, I do not want you to be bothered with DNS questions, so we will use for the local machine (the machine you are working on) the address 127.0.0.1. This special address is reserved for testing purposes on the local machine. It is also called the loopback address. So we will assume that the directory server runs on ldap://127.0.0.1:689 and the proxy server on ldap://127.0.0.1:389. I will also assume you installed and configured the directory server and you will start it up running on port 689.
