c# – Azure AD联合注销未重定向到客户端应用程序

我已将身份验证服务器配置为使用Open ID Connect身份提供程序,以允许用户使用混合流程对多租户Azure Active Directory帐户进行身份验证.

目前,登录按预期工作,我的客户端应用程序重定向到身份验证服务器,然后身份验证服务器重定向到Microsoft进行登录,然后返回到具有正确填充的访问令牌的客户端应用程序.

但是,当我尝试注销时,我被正确地重定向到Microsoft,但页面在返回到身份验证服务器时停止,而不是继续返回到我的客户端应用程序.

我相信我已按照here概述正确设置了邮寄注销重定向,我认为我的所有设置都可以.

当我下载Identity Server 3代码并调试它时,它正确地将signOutMessageId设置到查询字符串上,但是当它尝试重定向到我的映射的signoutcallback位置时,在UseAutofacMiddleware方法中遇到以下错误：

Exception thrown: ‘System.InvalidOperationException’ in mscorlib.dll

我的验证服务器设置：

app.Map("identity",idsrvApp => {
    var idSvrFactory = new IdentityServerServiceFactory();

    var options = new IdentityServerOptions
    {                
        SiteName = "Site Name",SigningCertificate = <Certificate>,Factory = idSvrFactory,AuthenticationOptions = new AuthenticationOptions
        {
            IdentityProviders = ConfigureIdentityProviders,EnablePostSignOutAutoRedirect = true,PostSignOutAutoRedirectDelay = 3
        }
    };
    idsrvApp.SetDefaultSignInAsAuthenticationType(CookieAuthenticationDefaults.AuthenticationType);
    idsrvApp.UseIdentityServer(options);

    idsrvApp.Map("/signoutcallback",cb => {
                    cb.Run(async ctx => {
                               var state = ctx.Request.Cookies["state"];
                               ctx.Response.Cookies.Append("state",".",new Microsoft.Owin.CookieOptions { Expires = DateTime.UtcNow.AddYears(-1) });
                               await ctx.Environment.RenderLoggedOutViewAsync(state);
                    });
                });
});

我的Open Id Connect设置连接到Azure AD：

app.USEOpenIdConnectAuthentication(
    new OpenIdConnectAuthenticationOptions
    {
        AuthenticationType = "aad",SignInAsAuthenticationType = signInAsType,Authority = "https://login.microsoftonline.com/common/",ClientId = <Client ID>,AuthenticationMode = AuthenticationMode.Active,TokenValidationParameters = new TokenValidationParameters
        {
            AuthenticationType = Constants.ExternalAuthenticationType,ValidateIssuer = false,},Notifications = new OpenIdConnectAuthenticationNotifications()
        {
            AuthorizationCodeReceived = (context) =>
            {
                var code = context.Code;
                ClientCredential credential = new ClientCredential(<Client ID>,<Client Secret>);
                string tenantId = context.AuthenticationTicket.Identity.FindFirst("tid").Value;
                AuthenticationContext authContext = new AuthenticationContext($"https://login.microsoftonline.com/{tenantId}");
                AuthenticationResult result = authContext.AcquireTokenByAuthorizationCode(
                            code,new Uri(<Identity Server URI>/aad/"),credential,"https://graph.windows.net");

                return Task.FromResult(0);
            },RedirectToIdentityProvider = (context) =>
            {
                string appBaseUrl = context.Request.Scheme + "://" + context.Request.Host + context.Request.PathBase;
                context.ProtocolMessage.RedirectUri = appBaseUrl + "/aad/";
                context.ProtocolMessage.PostLogoutRedirectUri = appBaseUrl + "/signoutcallback";

                if (context.ProtocolMessage.RequestType == Microsoft.IdentityModel.Protocols.OpenIdConnectRequestType.LogoutRequest)
                {
                    var signOutMessageId = context.OwinContext.Environment.GetSignOutMessageId();
                    if (signOutMessageId != null)
                    {
                        context.OwinContext.Response.Cookies.Append("state",signOutMessageId);
                    }
                }
                return Task.FromResult(0);
            }
    });

我找不到有关此问题的原因或解决方案的任何信息.如何将其配置为正确重定向回我的客户端应用程序？

关于GitHub的相关讨论：https://github.com/IdentityServer/IdentityServer3/issues/2657

我也在MyGet(v2.4.1-build00452)上使用最新版本的Identity Server尝试了同样的问题.

我还创建了一个存储库,可以在这里为我重现这个问题：https://github.com/Steve887/IdentityServer-Azure/
