Directory Objects

Choosing the plus button (+) or the minus button (-) next to an object in the directory expands or collapses it to show additional objects. An object that contains other objects is called a container. For example, choosing Recipients expands that container and displays its contents.

Use the Administrator program to manage your organization or site by manipulating the structure of the directory or changing the properties of individual objects. Objects are the building blocks of your information system. How you link them together and define their properties determines the structure of your organization. The following table shows the objects you can use to build an organization and includes a brief description of each object. An organization may or may not have all of the objects, depending on the configuration.
