     Centralized Management
        Centralized Management
Microsoft Active Directory is the heart of the Windows-based Hosting
centralized management solution. A centralized management system
allows you to create and manage server and user privileges,
authentication, and security within your hosting environment far more
efficiently than by using local user accounts and individual server
management. Using centralized management reduces operational
complexity, improves security, and lowers risk through consistent policy
application. The following table describes a complete list of server-
focused benefits.

centrally administered

                    Authentication
Authentication is the process by which the system validates a user's
logon information. A user's name and password are compared against
an authorized list, and if the system detects a match, access is granted
to the extent specified in the permission list for that user.

 Extensible Authentication Protocol
The Extensible Authentication Protocol (EAP) is an Internet Engineering Task
Force (IETF) standard (RFC 3478) that provides an infrastructure for network
access clients and authentication servers to host plug-in modules for current
and future authentication methods. Microsoft Windows uses EAP to
authenticate Point-to-Point Protocol (PPP)-based connections (such as dial-up,
virtual private network remote access, and site-to-site connections) and for
IEEE 802.1X-based network access to authenticating Ethernet switches and
wireless access points (APs). The following slide contains a drawing to
resources about EAP and its support in the current versions of Microsoft
Windows.
