This class is a custom System.EventArgs object that is used in the event handler for the PassportAuthenticationModule.Authenticate event. It provides three properties: Context, which provides a reference to the current System.Web.HttpContext; User, which will be a null reference and Identity, which will contain the information received from Passport as a PassportIdentity object.
You can implement a custom authentication scheme and set the User value programmatically to the appropriate user identity. If you do not set it to a non-null value, the PassportAuthenticationModule will create a System.Security.Principal.WindowsPrincipal object based on the information supplied in the PassportIdentity object and assign it to the System.Web.HttpContext.User property.
public sealed class PassportAuthenticationEventArgs : EventArgs { // Public Constructors public PassportAuthenticationEventArgs(PassportIdentity identity, System.Web.HttpContext context); // Public Instance Properties public HttpContext Context{get; } public PassportIdentity Identity{get; } public IPrincipal User{set; get; } }
