Web Authentication Process
Web authentication is a Layer 3 security feature that causes the controller to not allow IP traffic (except
DHCP-related packets) from a particular client until that client has correctly supplied a valid username
and password. When you use web authentication to authenticate clients, you must define a username and
password for each client. Then when the clients attempt to join the wireless LAN, their users must enter
the username and password when prompted by a login page.
When web authentication is enabled (under Layer 3 Security), users might receive a web-browser
security alert the first time that they attempt to access a URL. Figure 10-7 shows a typical security alert.
Figure 10-7 Typical Web-Browser Security Alert
After the user clicks Yes to proceed (or if the client’s browser does not display a security alert), the web
authentication system redirects the client to a login page (see Figure 10-8).
To prevent the security alert from appearing, the user can perform these steps:
Step 1 Click View Certificate on the Security Alert page.
Step 2 Click Install Certificate.
Step 3 When the Certificate Import Wizard appears, click Next.
Step 4 Choose Place all certificates in the following store and click Browse.
Step 5 At the bottom of the Select Certificate Store page, check the Show Physical Stores check box.
