Web Authentication for Mobile Users
Overview
Figure 5-2. The Web-Auth Process
Authentication Through a RADIUS Server
To allow mobile users to access the Internet and selected services on your
company’s network, you configure Web-Auth as the authentication method for
a WLAN and define a RADIUS server that verifies each user’s login credentials.
You can specify both a primary RADIUS server and a secondary RADIUS
server, ensuring high availability. If the primary RADIUS server is unavailable,
the Wireless Edge Services zl Module contacts the secondary RADIUS server.
The Wireless Edge Services zl Module provides an internal RADIUS server,
which you can use for Web-Auth. See Chapter 11: “RADIUS Server” for more
information.
