Authenticates user by checking the supplied user's token against the authentication store that this manager represents. This method is called by the framework after User object was deserialized and it's Rights need to be re-fetched. If token is invalid then UserStatus.Invalid is set. This method may populate user access rights completely or partially - depending on store implementation. If rights are computed on authentication than Authorize() just checks existing in-memory structure, otherwise Authorize() may re-fetch permissions from store on every call or cache them for the specified interval in memory
