In this configuration, you run a slapd(8) instance which provides directory service for your local domain only. It does not interact with other directory servers in any way. This configuration is shown in Figure 3.1.
Figure 3.1: Local service configuration.
Use this configuration if you are just starting out (it's the one the quick-start guide makes for you) or if you want to provide a local service and are not interested in connecting to the rest of the world. It's easy to upgrade to another configuration later if you want.
