Hi!
I just want to check if standard proxy with SSO AD authentication will fall back to basic authentication if logged in user is not domain user (local account or guest computer/user). According to my tests user is allowed to browse according to policy, but is not authenticated. There is no login pop up in browser. It is only possible to use "block if authentication fails" option, but I want to authenticate guest users to allow them access the internet - basic or browser authentication. Any advise how to configure this kind of authentication?
