如何集成OpenIDConnect＆AzureAD身份验证，而整个应用程序已通过WsFederate的pingfederate SSO进行了身份验证

Question

当前，使用PingFederate身份验证的Microsoft.Owin.Security.WsFederation SSO对应用程序进行身份验证。很好现在是新要求：在同一应用程序中的页面之一上单击按钮时，它应该在线集成到Office 365 Excel。为此，用户需要使用Office365凭据进行身份验证。 在我的示例演示中，当没有WsFederate和ping federate SSO身份验证时，我能够使用OpenIdConnect和Azure AD进行身份验证。但是，当我将现有代码与新的OpenIDConnect代码合并时，一切都会失败。作为Office365 Excel在线连接的一部分，我还需要使用Microsoft.Graph.Auth。

“启动类”中我当前的工作代码：

 public void ConfigureAuth(IAppBuilder app)
        {



            app.SetLoggerFactory(new DiagnosticsLoggerFactory());

            app.Use((context, next) =>
            {
                // Depending on the handler the request gets mapped to, a session might not be enabled. Force it on.
                HttpContextBase httpContext = context.Get<HttpContextBase>(typeof(HttpContextBase).FullName);
                httpContext.SetSessionStateBehavior(SessionStateBehavior.Required);
                return next();
            });

            // SetSessionStateBehavior must be called before AcquireState
            app.UseStageMarker(PipelineStage.MapHandler);

            app.UseCookieAuthentication(new CookieAuthenticationOptions
            {
                CookieHttpOnly = true,
                CookieSecure =  CookieSecureOption.Never,
                AuthenticationMode = AuthenticationMode.Active,
                AuthenticationType = WsFederationAuthenticationDefaults.AuthenticationType,
                Provider = new CookieAuthenticationProvider
                {
                    OnException = context =>
                    {
                        System.Diagnostics.EventLog.WriteEntry("WsFed-Exception", context.Exception.Message + "\n" + context.Exception.StackTrace );
                    }
                },
                ExpireTimeSpan = TimeSpan.FromHours(4.00),
                SlidingExpiration = true,
                CookieManager =  new SystemWebCookieManager()
            });

            app.UseWsFederationAuthentication(
                new WsFederationAuthenticationOptions
                {
                    MetadataAddress = ConfigurationManager.AppSettings[Constants.IDA_FEDERATION_METATADATA_LOCATION],
                    Wtrealm = ConfigurationManager.AppSettings[Constants.IDA_FEDERATION_REALM],
                    UseTokenLifetime = false,
                    SignInAsAuthenticationType = WsFederationAuthenticationDefaults.AuthenticationType
                }); 
        }

如何向其中添加OpenIdConnect？ 当使用WsFederate通过ping对应用程序进行身份验证时，是否可以将OpenIdConnect集成到同一应用程序启动类中？ 请引导我。
