I am using the individual user accounts part of .NET 4.5 to authenticate and authorise users to a RESTful API (http://www.asp.net/web-api/overview/security/individual-accounts-in-web-api)
However, I need to work out how to access the user ID from the bearer authorisation token, so I can return the data for the correct user.
How do I determine the correct user ID in a stateless API?
