CHAPTER 55
AAA Server
This chapter introduces and shows you how to configure the Zyxel Device to use external authentication
servers.
55.1 AAA Server Overview
You can use an AAA (Authentication, Authorization, Accounting) server to provide access control to
your network.
The following lists the types of authentication server the Zyxel Device supports.
•Local user database
The Zyxel Device uses the built-in local user database to authenticate administrative users logging into
the Zyxel Device’s web configurator or network access users logging into the network through the
Zyxel Device. You can also use the local user database to authenticate VPN users.
• Directory Service (LDAP/AD)
LDAP (Lightweight Directory Access Protocol)/AD (Active Directory) is a directory service that is both
a directory and a protocol for controlling access to a network. The directory consists of a database
specialized for fast information retrieval and filtering activities. You create and store user profile and
login information on the external server.
•RADIUS
RADIUS (Remote Authentication Dial-In User Service) authentication is a popular protocol used to
authenticate users by means of an external or built-in RADIUS server. RADIUS authentication allows
you to validate a large number of users from a central location.
55.2 Authentication Server Command Summary
