Does FluentSecurity replaces Asp.Net membership provider or it's supposed to complement/work together with it?

I'm working on an Asp.Net MVC4 site and I wanted to create a membership provided backed by Redis. Since I need the user privileges to be dynamic - user can create new roles in the admin dashboard - I was considering on using FluentSecurity (fluentsecurity.net) in the way explained in this SO question ASP.NET MVC3 Role and Permission Management -> With Runtime Permission Assignment.

So, my question is: Does FluentSecurity replaces Asp.Net membership system (or custom ones based on the membership provider pattern) or is it meant to augment it?
