How to enable ClearPass Guest captive portal access over HTTP only
If a network admin is testing captive portal setup in lab (without HTTPS certificate installed on the CPPM) and wants to access the page over HTTP only, then how to achieve it?
Apart from configuring the captive portal URL (with HTTP) on the controller/switch, we need to modify a setting on ClearPass Guest as well (mentioned in screenshot below). By default any HTTP captive portal access request is redirected to use HTTPS instead.
If one does not have a HTTPS certificate installed on ClearPass (from a well known CA) then setting the captive portal over HTTPS would cause cert warnings. In order to avoid the cert warning we need to uncheck the "Security" box mentioned above.
