• Open Central Administration Console.
  • Click on Manage Web application Under Application Management.
  • Click on new on the Ribbon.
  • Chose Claims based Authentication From the top of the page.
  • Choose the port no for the web application.
  • Click on Enable Forms Based Authentication (FBA) Under Claims Authentication Types. Windows Authentication is enabled by default and if you dont need windows authentication then you need to remove the check the box.
  • Add the Membership Provider & Role Manager Name
  • As soon as web application has been created please verify the Authentication Provider settings for the web application. I have the screenshot below:

Note: Just for understanding, Membership Provider as “SQL-MembershipProvider” and Role Manager as “SQL-RoleManager”  can use different names, however you need to remember the name so that you can refer them in web.config files. These names are case sensitive.
