I have an issue with the standard ASP Identity provider for MVC5. As soon as I log in the method:
await SignInManager.PasswordSignInAsync(model.Email, model.Pass
ApplicationUser signedUser = UserManager.FindByEmail(model.Email);
var result = await SignInManager.PasswordSignInAsync(signedUser.UserName,
model.Password, model.RememberMe, shouldLockout: false);
This worked for me becouse my username was not equal my email. Your email and username should be the same.
