IDX21323 OpenIdConnectProtocolValidationContext.Nonce was null, OpenIdConnectProtocolValidatedIdToken.Payload.Nonce was not null

Question

I'm attempting to authenticate for Azure AD and Graph for an Intranet (Based off Orchard CMS), this functions as expected on my local machine, however, when accessing what will be the production site (already set up with ssl on our internal dns), I get the above error at times, it's relatively inconsistent, others in my department while accessing usually get this error.

My Authentication Controller is as follows:

public void LogOn()
    {
        if (!Request.IsAuthenticated)
        {

            // Signal OWIN to send an authorization request to Azure.
            HttpContext.GetOwinContext().Authentication.Challenge(
              new AuthenticationProperties { RedirectUri = "/" },
              OpenIdConnectAuthenticationDefaults.AuthenticationType);
        }
    }

    public void LogOff()
    {
        if (Request.IsAuthenticated)
        {
            ClaimsPrincipal _currentUser = (System.Web.HttpContext.Current.User as ClaimsPrincipal);

            // Get the user's token cache and clear it.
            string userObjectId = _currentUser.Claims.First(x => x.Type.Equals(ClaimTypes.NameIdentifier)).Value;

            SessionTokenCache tokenCache = new SessionTokenCache(userObjectId, HttpContext);
            HttpContext.GetOwinContext().Authentication.SignOut(OpenIdConnectAuthenticationDefaults.AuthenticationType, CookieAuthenticationDefaults.AuthenticationType);
        }

        SDKHelper.SignOutClient();

        HttpContext.GetOwinContext().Authentication.SignOut(
          OpenIdConnectAuthenticationDefaults.AuthenticationType, CookieAuthenticationDefaults.AuthenticationType);
    }

My openid options are configured as follows:

AntiForgeryConfig.UniqueClaimTypeIdentifier = ClaimTypes.NameIdentifier;

        var openIdOptions = new OpenIdConnectAuthenticationOptions
        {
            ClientId = Settings.ClientId,
            Authority = "https://login.microsoftonline.com/common/v2.0",
            PostLogoutRedirectUri = Settings.LogoutRedirectUri,
            RedirectUri = Settings.LogoutRedirectUri,
            Scope = "openid email profile offline_access " + Settings.Scopes,
            TokenValidationParameters = new TokenValidationParameters
            {
                ValidateIssuer = false,
            },
            Notifications = new OpenIdConnectAuthenticationNotifications
            {
                AuthorizationCodeReceived = async (context) =>
                {
                    var claim = ClaimsPrincipal.Current;
                    var code = context.Code;                        

                    string signedInUserID = context.AuthenticationTicket.Identity.FindFirst(ClaimTypes.NameIdentifier).Value;


                    TokenCache userTokenCache = new SessionTokenCache(signedInUserID,
                        context.OwinContext.Environment["System.Web.HttpContextBase"] as HttpContextBase).GetMsalCacheInstance();
                    ConfidentialClientApplication cca = new ConfidentialClientApplication(
                        Settings.ClientId,
                        Settings.LogoutRedirectUri,
                        new ClientCredential(Settings.AppKey),
                        userTokenCache,
                        null);


                    AuthenticationResult result = await cca.AcquireTokenByAuthorizationCodeAsync(code, Settings.SplitScopes.ToArray());
                },
                AuthenticationFailed = (context) =>
                {
                    context.HandleResponse();
                    context.Response.Redirect("/Error?message=" + context.Exception.Message);
                    return Task.FromResult(0);
                }
            }
            };

        var cookieOptions = new CookieAuthenticationOptions();
        app.SetDefaultSignInAsAuthenticationType(CookieAuthenticationDefaults.AuthenticationType);

        app.UseCookieAuthentication(cookieOptions);

        app.UseOpenIdConnectAuthentication(openIdOptions);

The url for redirection is kept consistent both at apps.dev.microsoft.com and in our localized web config.

Answer 1

In my case, this was a very weird problem because it didn't happen in for everyone, only few clients and devs have this problem.

If you are having this problem in chrome only (or a browser that have the same engine) you could try setting this flag on chrome to disabled.

What happens here is that chrome have this different security rule that " If a cookie without SameSite restrictions is set without the Secure attribute, it will be rejected". So you can disable this rule and it will work.

OR, you can set the Secure attribute too, but I don't know how to do that ;(

Answer 2

Check the URL mentioned in the AD App Registrations --> Settings --> Reply URL's. if for example that url is https://localhost:44348/

Go to MVC Project --> Properties (Right Click and Properties) --> Web Section --> Start URL and Project URL should also be https://localhost:44348/

This has resolved the issue for me. other option is to dynamically set the Redirect URL after AD authentication in Startup.Auth
