Single sign on 如何使用ADFS联合为所有应用程序实现单次注销

我将使用带联合服务的本地ADFS 4.0实现SSO。我已经为登录和它的工作做了很好的代码，但我想开发单一的注销功能

当我从一个网站注销时，用户必须自动从ADFS服务器中配置的所有应用程序注销

以下是我的代码：

StartUp.Auth文件

            string adfs = ConfigurationManager.AppSettings["AdfsMetadataEndPoint"];
            string realm = ConfigurationManager.AppSettings["Wtrealm"];
            string reply = ConfigurationManager.AppSettings["Wreply"];

            app.UseCookieAuthentication(new CookieAuthenticationOptions
            {
                AuthenticationType = CookieAuthenticationDefaults.AuthenticationType,
                CookieManager = new SystemWebCookieManager()
            });

            app.UseWsFederationAuthentication(new WsFederationAuthenticationOptions
            {
                MetadataAddress = adfs,
                Wtrealm = realm,
                Wreply = reply,
                AuthenticationMode = AuthenticationMode.Passive
            });

            app.SetDefaultSignInAsAuthenticationType(CookieAuthenticationDefaults.AuthenticationType);

注销操作：

public void LogOff()
        {
            var owinContext = this.Request.GetOwinContext();
            var authProperties = new AuthenticationProperties();
            authProperties.RedirectUri = new Uri(this.HttpContext.Request.Url, new UrlHelper(this.ControllerContext.RequestContext).Action("Login")).AbsoluteUri;

            owinContext.Authentication.SignOut(authProperties);

            WSFederationAuthenticationModule.FederatedSignOut(
                new Uri("https://xxxxxxx/adfs/ls/?wa=wsignoutcleanup1.0"),
                new Uri("https://localhost:44320/Home/Index"));

            //AuthenticationManager.SignOut(DefaultAuthenticationTypes.ApplicationCookie);
            //return RedirectToAction("Index", "Home");
        }

问题是什么？此外，SLO通常是SAML特性。我使用的是联合而不是SAML
