Hi Experts,
I have a little confusing on external portal authentication of WLC.
If I am using external portal on WLC, what action will WLC do ?
First ,The WLC redirect http or https traffic of client to external portal and intercept username and password, then send to AAA server to authentication.
Sencond, The WLC redirect http or https traffic of client to external portal, then external portal sending authentication failed or success message to WLC. The WLC will permit or deny client depending on external portal authentication message.
From my opinion, the first action is correct. But HTTPS is encrypted, how can WLC intercept username and password if using a HTTPS external portal?
