userState

Token identifying the asynchronous operation

Login may be used to validate a user's credentials and provide more secure communications between client and server tiers. In a Silverlight application, you can integrate with ASP.NET authentication features when the UseAspNetSecurityServices option is enabled.

If EntityManagerOptions.UseDefaultAuthenticationContext is true, the LoginAsync call will set the IdeaBlade.EntityModel.Security.Authenticator.DefaultAuthenticationContext, otherwise the AuthenticationContext is set.

Credentials are passed in clear text. Use a secure channel (such as SSL) or provide your own encryption if secure communications are necessary.
