FortiNAC common deployment

Hello community, Im once again dealing with FortiNAC, as my company is been back and forwards with it.

For example using Cisco ISE, we configure 802.1x on the switches, Cisco ISE validates certificate or username (if im not mistaken) and thats usually the way to go with ISE.

My question is: whats the equivalent of what I mentioned for ISE on FortiNAC? Does it support 802.1x at all in the same way ISE does? And if it does, is that the common way to go with FortiNAC. If not, well, whats the common way to go?

I got that FortiNAC support a lot of protocols, but thats actually what confuses me, it supports so many stuff that I don't know what to do or whats normally done out there in most scenarios (even though no environments are the same :)

I guess Im asking for a practical aspect, I would like to know how are the most FortiNACs deployed out there, real case scenario in this aspect based on real world experience deploying/managing this monster.
