Configuring Custom Web-Auth Pages
You can design your own Web-Auth pages and either store them on an external
server or upload them to the Wireless Edge Services xl Module’s flash memory
(advanced configuration). The custom Web-Auth pages must include a login
page, a welcome page, and a failed page. However, in addition to those pages,
you can configure links to as many other pages as you desire.
To enable Web-Auth support, you must incorporate specific CGI code on both
the login page and the welcome page:
■ Login page—You must include CGI code that allows users to enter their
login credentials and then send these credentials to the Wireless Edge
Services xl Module. The module, in turn, submits this information to the
RADIUS server.
■ Welcome page—You must include CGI code that disconnects the user’s
station from your company’s network services and displays the login page
again.
You do not need to include any specific CGI commands on the failed page;
however, you might want to include a link back to the login page, as the default
failed page does.
Configuring the CGI Commands for the Login Page
When you create the login page, you can include any text and graphical
elements that you want as long as you include the CGI code shown in
Figure 5-24 (for an external page) or Figure 5-25 (for a custom page stored on
the module). The required code includes the commands that submit the user’s
login credentials to the Wireless Edge Services xl Module. When the page is
stored on an external server, you must specify the IP address of the module
before the reference to the CGI commands. When you are using pages that
you have loaded to the module’s flash memory with advanced configuration,
the IP address is unnecessary.
In addition, the CGI code shown in Figure 5-24 and Figure 5-25 configures a
small form that includes a username field and a password field. You can
customize the font and the appearance of the form as needed to fit the other
design elements on your company’s login page.
