I am trying to understand the mechanics of the last part of authentication and final step in internet access for guest clients.
In my scenario I have a ClearPass setup that returns the string server.customer.com instead of the securelogin.arubanetworks.com default cert.
What happens with this string when passed back to the controller/client - does the client do a DNS lookup for this?.
I read somewhere this is the case and the controller then intercepts this and does something with this request but I'm not sure specifically what.
I would appreciate some help understanding this so I can fill in the blanks.
