Customizing AuthModeAttribute¶

Below is an example of overriding the HandleUnauthorizedRequest method to redirect to the STS login page. This is helpful as a filter if you require a particular authentication mode for your application.

public class MyAuthModeAttribute : AuthModeAttribute    
{
        public MyAuthModeAttribute(AuthenticationMode[] authModes) : base(authModes){}
        public MyAuthModeAttribute(AuthenticationMode authMode) : base(new []{authMode}){}

        public override void OnAuthorization(AuthorizationContext filterContext)
        {
            if (AuthorizeCore(filterContext.HttpContext))
            {
                base.OnAuthorization(filterContext);
            }
            else
            {
                HandleUnauthorizedRequest(filterContext);
            }
        }


        protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)
        {
            if (!Signout(filterContext))
            {
                filterContext.HttpContext.Response.Redirect("~/Home/Error");
                base.HandleUnauthorizedRequest(filterContext);
            }
        }

        private const string logoutString = "{0}?wa=wsignout1.0&wtrealm={1}";
        private bool Signout(AuthorizationContext filterContext)
        {
            if (filterContext != null && filterContext.HttpContext != null && filterContext.HttpContext.Request != null && filterContext.HttpContext.Request.Url!=null)
            {
                var rootUrl = filterContext.HttpContext.Request.Url.GetLeftPart(UriPartial.Authority);

                var signoutUrl = string.Format(logoutString,
                    FederatedAuthentication.FederationConfiguration.WsFederationConfiguration.Issuer,
                    HttpUtility.UrlEncode(rootUrl));
                FederatedAuthentication.WSFederationAuthenticationModule.SignOut(signoutUrl);
                return true;
            }
            return false;
        }
}
