I want to enable the ASP.NET MVC 4\'s SimpleMembership API to integrate with my own database schema. I have a plain and simple table in my database called Users
I asked the same question to the product team.
The design goal of SIMPLE membership was to work out-of-the box as simple as possible.
So really there's no customization possible as far as the tables are concerned. The recommended workaround is, to still use ASP.NET Membership (SqlMembershipProvider).
