FortiConnect integration

Hello guys,

I've just discovered the FortiConnect product, which will be very useful to me for an hotel which is looking for a cheap, easy to use captive portal.

However, i can't find precise documention to ingregate it to the FortiGate. I've followed the admin guide, but when a clients login to the portal, i get an loop back to the login page, even tho the account is created and valid :(

Do you have any experience with the product? Any white papers out there?
