Wifi Guest Captive Portal Encryption and Sponsors

Hello,

We are going to deploy FortiAP with FortiWLC and FortiAuthenticator, I would like to know if fallowing scenario is possible within FortiAuthenticator solution.

1. Can Guest's SSID with Captive Portal be encrypted?

2. Can we have self-registration portal whereas guest must prompt into free text field an email address of person who will be a sponsor/admin and will approve such registration?

3. Can we white-list e-mail addresses from scenario above?

4. Do I need to have FortiConnect to accomplish those scenarios?

Thanks in advance,

G
