User.Identity.IsAuthenticated is false after Security.login()

[yuri-martynov]

HttpContext.Current.User.Identity.GetUserId() returns null
How to get userId on server side?

[JustMaier]

Strange - can you look and see if the authenticated headers are being sent with requests after Security.login?

Headers is OK.
With GlobalConfiguration.Configuration.SuppressDefaultHostAuthentication() I have Authenticated User in Web API controller method. Without SuppressDefaultHostAuthentication() I have it much earlier, in Controller constructor and in time DI takes place. Actually I used HttpContext.Current.User.Identity.GetUserId() with DI to inject it to services (not Web API controller) that have not access to User.
