we have 2x Wireless networks configured in Central, the guest network uses a captive portal and integrates with clearpass(from what I understand). The issue is that once guest user details have been entered and the named sponsor has accepted Guest access is indefinite. For example I connected to the Guest network intially when joining the comapny a month ago and even now I can just click on Guest and I do not have to re-auth, I have full internet access, etc. I see that when guest users are provisioned manually there is a start date and end date; how can I apply this/similar in Clearpass to sponsored user accounts?
