Session Objectives

usefulness.
Directory Services






A directory service provided by a network operating system is
a way of centrally managing your network,
They often have a WIMP interface which visually displays
different network components,
The main purpose of Active Directory (used by MS Windows
servers) is to provide central authentication and authorization
services for Windows based computers,
Active Directory also allows administrators to assign policies,
deploy software, and apply critical updates to an entire
organization.
Active Directory stores information and settings relating to an
organization in a central, organized, accessible database.
Active Directory networks can vary from a small installation
with a few hundred objects, to a large installation with
millions of objects.
