Cisco Wireless: WebAuth on WLC

Web Authentication

WebAuth is an authentication method without encryption. It provides Layer 3 security.

WebAuth with Local WLC

  1. The client (end user) opens a web browser and enters a URL.
  2. Client resolves URL using DNS
  3. Client sends HTTP request to IP address of the site
  4. The WLC URL sends the user to a login page.
  5. If authentication is successful, the WLC web server either forwards the user to the configured redirect URL or to the URL the client entered.

Web Passthrough

It displays a page with a warning or an alert statement, but does not prompt for credentials.
