Simple multi-tenant solution.
This is a multi-tenant solution that uses as a based the popular NHibernate.AspNet.Identity library.
The way that the library has been extended to support multi-tenancy is by adding a new property to the IdentityUser that identifies to which tenant the user belongs to.
The reason why I call it a simple multi-tenant solution is because a single email address can only belong to a single tenant. Many will agree and disagree that this is not a multi-tenant solution, however I think that this is at least the most simple solution to achieve multi-tenancy.
