  • 1.  Clearpass authentication EAP-PEAP - Public certificates possible?

    Posted Jul 19, 2022 04:06 AM

    Hi all,

     

    I have a customer with Aruba Clearpass where they use EAP-PEAP as authentication method to the guest wireless for their BYOD users. To be more specific, patients in a hospital. Solution for authentication is Clearpass Guest.

     

    Is there any best practice for the certificate? On iOS you can trust this easily when connecting, however Android 11 now removed the option to not verify the server certificate which appears as self-signed, however this is a public one from SSL Certificate provider.

     

    Isn't there any option for such case to work with public certificates so that this appears as trusted and everyone can connect seamless?

     

    It's a shame that this can only work smoothly for managed devices on which you can push the certificate. Alternative I can think of is to work with a 'provisioning' page where users have to load certificate first? I'd rather avoid onboard.

     

    Thanks for your advice!

    For a guest WLAN if you are using https, you need a certificate issued by a certificate authority that is trusted by all clients on both the controller doing the redirect and the ClearPass guest device.  If you don't, you will get random errors in your browser, or even IOS not processing the redirect randomly.

    EAP-PEAP for a public network is not practical due to the many issues with setting up endpoints for EAP-PEAP.  It would be too cumbersome.

    If you have patients in a hospital, where the average age is 70, you would need to make it as easy as possible to get online otherwise nobody will use it.

    Reason that there is no automatic trust, is that unlike with web-sites where there is in DNS an official registration of the domain name, such a registration does not exist for WiFi networks SSIDs. Anyone can pick any SSID, so there is no way to tie that properly to a certificate.

    So no, there are no (public, private) certificates that allow users to connect without certificate warnings/proper client configuration.
