AAA Server

37.1 Overview

You can use a AAA (Authentication, Authorization, Accounting) server to provide access control to your network. The AAA server can be a Active Directory, LDAP, or RADIUS server. Use the AAA Server screens to create and manage objects that contain settings for using AAA servers. You use AAA server objects in configuring ext-group-user user objects and authentication method objects (see Chapter 38 on page 583).

37.1.1 Directory Service (AD/LDAP)

LDAP/AD allows a client (the ZyWALL) to connect to a server to retrieve information from a directory. A network example is shown next.

Figure 339 Example: Directory Service Client and Server

The following describes the user authentication procedure via an LDAP/AD server.

1A user logs in with a user name and password pair.

2The ZyWALL tries to bind (or log in) to the LDAP/AD server.

3When the binding process is successful, the ZyWALL checks the user information in the directory against the user name and password pair.

4If it matches, the user is allowed access. Otherwise, access is blocked.
