I have recently seen this video here: https://www.youtube.com/watch?v=9AUki6_lJPA
So, in short - the guy makes 3 wlans and 3 roles so that each role can connect just to 1 wlan. And then he makes a provisioning hotspot where users authenticate using username and password, and get automatically redirected to their wlan (zero-it activation). Can someone point out to me what are the benefits of this approach compared to not having a provisioning wlan, but instead users connect to their wlan and then autenthicate there using a username/password combination (802.1x using internal database on the controller).
It seems to me that it's just one wlan more (the hotspot) for the same service, but surely I'm wrong.
