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 window.
When web authentication is enabled (under WLAN Security Policies), users might receive a
web-browser security alert the first time that they attempt to access a URL. Figure 9-7 shows a typical
security alert.
Figure 9-7 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 window.
