title: Validate user in project that is using OWIN auth middleware
body: <p>I am building a ASP.NET MVC 5 project that is using OWIN authentication middle-ware. </p>
  
  <p>Part of the application is using Basic (or some custom) authentication. I have user name and password on the server side that I need to validate against the users database storage (this is a standard Visual Studio 2013 project with no changes).</p>
  
  <p>In the past I was using membership provider to validate the user:</p>
  
  <pre><code>Membership.ValidateUser(userName, password)
  </code></pre>
  
  <p>What do I use in case of OWIN? Should I call SignInManager.PasswordSignInAsync?</p>
