Wireless Access Point
288 Configuring the Wireless AP
External Login page
This option redirects the user to a login page on an external web server
for authentication, instead of the first user-requested URL. Login
information (user name and password) must be obtained by that page,
and returned to the AP for authentication.
Authentication occurs according to your configured RADIUS
information. These parameters are configured as described in “Procedure
for Configuring Network Security” on page 249, except that the RADIUS
Authentication Type is selected here, as described below. After
authentication, the browser is redirected back to the captured URL. If you
want the user redirected to a specific landing page instead, enter its
address in Landing Page URL.
To set up external login page usage, set Server to External Login. Enter
the URL of the external web server in Redirect URL, and enter that
server’s shared secret in Redirect Secret.
Select the RADIUS Authentication Type. This is the protocol used for
authentication of users, CHAP or PAP (the default).
• Password Authentication Protocol (PAP), is a simple protocol. PAP
transmits ASCII passwords over the network “in the clear”
(unencrypted) and is therefore considered insecure.
• Challenge-Handshake Authentication Protocol (CHAP) is a more
secure Protocol. The login request is sent using a one-way hash
function.
External Splash page
This option displays a splash page instead of the first user-requested
URL. The splash page files reside on an external web server.
To set up external splash page usage, set Server to External Splash. Enter
the URL of the external web server in Redirect URL, and enter that
server’s shared secret in Redirect Secret.
