title: Multi-tenant using Aspnet Identity
body: <p>I am trying to create a MVC5 multi-tenant application using Aspnet Identity.  I have done some research and found other answers, <a href="https://stackoverflow.com/questions/20037145/how-to-implement-multi-tenant-user-login-using-asp-net-identity">How to implement Multi-tenant User Login using ASP.NET Identity</a>, that provides a nuget package for implementation.  Than problem that I have is that the tenant is specified in the constructor of the ApplicationUserStore.  </p>
  
  <p>I need to have users go to a login screen from which they choose from a list of available tenant options and then authenticate the user against the chosen tenant.  </p>
  
  <p>Does anyone know how to modify the above solution to meet my needs or have another option?</p>
