Networking: A Beginner's Guide
You should know about five important directory services: Novell eDirectory,
Microsoft's Windows NT domains, Microsoft's Active Directory, X.500 Directory Access
Protocol, and Lightweight Directory Access Protocol. These are described later in this
chapter.
Forests, Roots, Trees, and Leaves
One thing common to all directory services is a tree-based organization (with the
tree usually depicted upside-down with the root at the top), somewhat similar to the
organization of directories on a hard disk. A forest is a collection of trees managed
collectively. At the top of each directory tree is the root entry, which contains other
entries. These other entries can be containers or leaves. A container object is one that
contains other objects, which can also include more containers and leaves. A leaf object
represents an actual resource on the network, such as a workstation, printer, shared
directory, file, or user account. Leaf objects cannot contain other objects. Figure 9-1
shows a typical directory tree.
