  Azure Ad problem with CORS policy

  Apr 16, 2020 09:46 AM|IamGuy84|LINK

  Dear folks,

  I am using Asp.net core with SPA (Angular). I have created app registration with authentication on Azure portal as below:
  
  

  In appsettings.json:

    "AzureAd": {
      "Instance": "https://login.microsoftonline.com/",
      "Domain": "XXXX.onmicrosoft.com",
      "TenantId": "2c614b94-XXXX-408e-8800-XXXXXX",
      "ClientId": "894782b8-XXXX-4214-976f-XXXXXX",
      "CallbackPath": "/signin-oidc"
    },

  In Sartup.cs:

  ................................... 
  static readonly string _RequireAuthenticatedUserPolicy = "RequireAuthenticatedUserPolicy";
  
          public void ConfigureServices(IServiceCollection services)
          {
  
              services.Configure<CookiePolicyOptions>(options =>
              {
                  // This lambda determines whether user consent for non-essential cookies is needed for a given request.
                  options.CheckConsentNeeded = context => true;
                  options.MinimumSameSitePolicy = SameSiteMode.None;
              });
  
              services.AddAuthentication(AzureADDefaults.AuthenticationScheme)
                  .AddAzureAD(options => Configuration.Bind("AzureAd", options));
  
              services.Configure<OpenIdConnectOptions>(AzureADDefaults.OpenIdScheme, options =>
              {
                  options.Authority = options.Authority + "/v2.0/";         // Microsoft identity platform
  
                  options.TokenValidationParameters.ValidateIssuer = false; // accept several tenants (here simplified)
              });
  
              services.AddAuthorization(o => o.AddPolicy(_RequireAuthenticatedUserPolicy,
                   builder => builder.RequireAuthenticatedUser()));
  
             ................
          }

  I run the project and I am getting error message and it says as below:
  
  

  Could you please help to resolve this issue?
  I am waiting for your response.
  
  Thanks in advance

  Hi IamGuy84,

  As far as I know, if you want to angular to login with AAD, you should AAD angular library.

  More details about how to use it , you could refer to below article.

  Best Regards,

  Brando
