ASP MVC 5. Authentication and authorization?

Question

ASP.NET

How is your system of authentication and authorization on projects arranged, your own implementation (if a brief example is possible) or a ready-made OWIN, simple membership provider. I can’t understand how to use the finished owin without violating my domain model where there is a user.
where can I get an exhaustive version for beginners on the topic ... with examples owin

Answer 1

I do it myself, a rough example

//Вход
var claims = new List<Claim>();
claims.Add(new Claim(ClaimTypes.Name, "Brock"));
claims.Add(new Claim(ClaimTypes.Email, "[email protected]"));
var id = new ClaimsIdentity(claims,DefaultAuthenticationTypes.ApplicationCookie);
var ctx = Request.GetOwinContext();
var authenticationManager = ctx.Authentication;
authenticationManager.SignIn(id);

//Выход
var ctx = Request.GetOwinContext();
var authenticationManager = ctx.Authentication;
authenticationManager.SignOut();
