Microsoft Outlook connection using Graph #12032 | Support Center

Bernard created 5 months ago

Hi,

I'm trying to implement the ability to read Outlook emails in my application (https://learn.microsoft.com/en-us/training/modules/msgraph-dotnet-core-show-user-emails/1-introduction), but I'm facing a problem because Graph needs to launch the services services // Add support for OpenId authentication .AddAuthentication(OpenIdConnectDefaults.AuthenticationScheme) failed

because an OpendConnectId Schema already exists

I think This code causes issue in Startup.cs

services // 2. Add support for OpenId authentication

.AddAuthentication(OpenIdConnectDefaults.AuthenticationScheme)

.AddMicrosoftIdentityWebApp(Configuration)

How to fix this problem THANKS

Hi @Bernard,

Have you tried removing the line below ?

.AddAuthentication(OpenIdConnectDefaults.AuthenticationScheme) Cause issue

Hi,

Any idea ? For having 2 schemes when Connecting ?

I think it should be something like this : https://stackoverflow.com/questions/49694383/use-multiple-jwt-bearer-authentication but for Openconnect

Hi,

Does this work https://github.com/AzureAD/microsoft-identity-web/wiki/multiple-authentication-schemes ?

I follow your example like :

  var authenticationBuilder = services.AddAuthentication();

  if (bool.Parse(configuration["Authentication:OpenId:IsEnabled"]))
  {
      if (bool.Parse(configuration["Authentication:AllowSocialLoginSettingsPerTenant"]))
      {
          services.AddSingleton&lt;IOptionsMonitor&lt;OpenIdConnectOptions&gt;, TenantBasedOpenIdConnectOptions>();
      }

      authenticationBuilder.AddOpenIdConnect(options =>
      {
          options.ClientId = configuration["Authentication:OpenId:ClientId"];
          options.Authority = configuration["Authentication:OpenId:Authority"];
          options.SignedOutRedirectUri = configuration["App:WebSiteRootAddress"] + "Account/Logout";
          options.ResponseType = configuration["Authentication:OpenId:ResponseType"];

          options.TokenValidationParameters = new TokenValidationParameters()
          {
              ValidateIssuer = bool.Parse(configuration["Authentication:OpenId:ValidateIssuer"])
          };

          options.Events.OnTokenValidated = context =>
          {
              var jsonClaimMappings = new List&lt;JsonClaimMap&gt;();
              configuration.GetSection("Authentication:OpenId:ClaimsMapping").Bind(jsonClaimMappings);

              context.AddMappedClaims(jsonClaimMappings);

              return Task.FromResult(0);
          };

          var clientSecret = configuration["Authentication:OpenId:ClientSecret"];
          if (!clientSecret.IsNullOrEmpty())
          {
              options.ClientSecret = clientSecret;
          }
      });

  };


  authenticationBuilder.AddMicrosoftIdentityWebApp(configuration.GetSection("AzureAd"))
  .EnableTokenAcquisitionToCallDownstreamApi(configuration.GetValue&lt;string&gt;("DownstreamApi:Scopes")?.Split(' '))
      .AddMicrosoftGraph(configuration.GetSection("DownstreamApi"))
      .AddInMemoryTokenCaches();

but it cause issue

Hi Ismail,

I finally found the good way :

// Retrieve required permissions from appsettings string[] initialScopes = configuration.GetValue<string>("DownstreamApi:Scopes")?.Split(' ');

var authenticationBuilder = services.AddAuthentication(options => { options.DefaultScheme = "OpenIdConnect"; options.DefaultChallengeScheme = "AzureAd";

if (bool.Parse(configuration["Authentication:OpenId:IsEnabled"])) { if (bool.Parse(configuration["Authentication:AllowSocialLoginSettingsPerTenant"])) { services.AddSingleton<IOptionsMonitor<OpenIdConnectOptions>, TenantBasedOpenIdConnectOptions>(); }

  authenticationBuilder.AddOpenIdConnect(options =>
  {
      options.ClientId = configuration["Authentication:OpenId:ClientId"];
      options.Authority = configuration["Authentication:OpenId:Authority"];
      options.SignedOutRedirectUri = configuration["App:WebSiteRootAddress"] + "Account/Logout";
      options.ResponseType = configuration["Authentication:OpenId:ResponseType"];

      options.TokenValidationParameters = new TokenValidationParameters()
      {
          ValidateIssuer = bool.Parse(configuration["Authentication:OpenId:ValidateIssuer"])
      };

      options.Events.OnTokenValidated = context =>
      {
          var jsonClaimMappings = new List&lt;JsonClaimMap&gt;();
          configuration.GetSection("Authentication:OpenId:ClaimsMapping").Bind(jsonClaimMappings);

          context.AddMappedClaims(jsonClaimMappings);

          return Task.FromResult(0);
      };

      var clientSecret = configuration["Authentication:OpenId:ClientSecret"];
      if (!clientSecret.IsNullOrEmpty())
      {
          options.ClientSecret = clientSecret;
      }
  })**.AddMicrosoftIdentityWebApp(options =>
  {
      options.ClientId = configuration["Authentication:AzureAd:ClientId"];
      options.Instance= configuration["Authentication:AzureAd:Instance"];
      options.TenantId = configuration["Authentication:AzureAd:TenantId"];
      options.SignedOutRedirectUri = configuration["App:WebSiteRootAddress"] + "Account/Logout";
    
      var clientSecret = configuration["Authentication:AzureAd:ClientSecret"];
      if (!clientSecret.IsNullOrEmpty())
      {
          options.ClientSecret = clientSecret;
      }
  }, null, "AzureAd")
  .EnableTokenAcquisitionToCallDownstreamApi(initialScopes)
  .AddMicrosoftGraph(configuration.GetSection("DownstreamApi"))

Hi,

The OpenconnectId and Microsoft graph connection seems to work well now. But I'm facing another issue now. When I want to view emails I am systemically redirected by this method which seems to pose an issue.

ERUDYEntityFrameworkCoreModule

[DependsOn( typeof(AbpZeroCoreEntityFrameworkCoreModule), typeof(ERUDYCoreModule) )] public class ERUDYEntityFrameworkCoreModule : AbpModule { /* Used it tests to skip DbContext registration, in order to use in-memory database of EF Core */ public bool SkipDbContextRegistration { get; set; }

 public bool SkipDbSeed { get; set; }

 public override void PreInitialize()
 {
     if (!SkipDbContextRegistration)
     {
         Configuration.Modules.AbpEfCore().AddDbContext&lt;ERUDYDbContext&gt;(options =>
         {
             if (options.ExistingConnection != null)
             {
                 ERUDYDbContextConfigurer.Configure(options.DbContextOptions,
                     options.ExistingConnection);
             }
             else
             {
                 ERUDYDbContextConfigurer.Configure(options.DbContextOptions,
                     options.ConnectionString);
             }
         });
     }

     // Set this setting to true for enabling entity history.
     Configuration.EntityHistory.IsEnabled = false;

     // Uncomment below line to write change logs for the entities below:
     // Configuration.EntityHistory.Selectors.Add("ERUDYEntities", EntityHistoryHelper.TrackedTypes);
     // Configuration.CustomConfigProviders.Add(new EntityHistoryConfigProvider(Configuration));
 }

 public override void Initialize()
 {
     IocManager.RegisterAssemblyByConvention(typeof(ERUDYEntityFrameworkCoreModule).GetAssembly());
 }

 public override void PostInitialize()
 {
     var configurationAccessor = IocManager.Resolve&lt;IAppConfigurationAccessor&gt;();

     using (var scope = IocManager.CreateScope())
     {
         if (!SkipDbSeed && scope.Resolve&lt;DatabaseCheckHelper&gt;()
                 .Exist(configurationAccessor.Configuration["ConnectionStrings:Default"]))
         {
             SeedHelper.SeedHostDb(IocManager);
         }
     }
 }

}

And the resut email display is :

Have you an idea of what causes this issue ?

Hi @Bernard

Are there any error logs on the server side ? If so, could you share it ?

Hi @Bernard,

Can you repeat the error and send us the error log that occurred at that time?

If you are using an Angular project it is located in: *.Host > App_Data > Logs other way it is located in *.Mvc> App_Data > Logs

Hi @Bernard,

When I examine the logs, I see they have the same error. Can you try setting the authentication scope where you use the code, like the document?

Hi,

Same issue with this code :

if (bool.Parse(configuration["Authentication:OpenId:IsEnabled"])) { //if (bool.Parse(configuration["Authentication:AllowSocialLoginSettingsPerTenant"])) //{ // services.AddSingleton<IOptionsMonitor<OpenIdConnectOptions>, TenantBasedOpenIdConnectOptions>(); //}

  services
  // Add support for OpenId authentication
  .AddAuthentication(OpenIdConnectDefaults.AuthenticationScheme)
  .AddMicrosoftIdentityWebApp(configuration, "Authentication:AzureAd")
  .EnableTokenAcquisitionToCallDownstreamApi(initialScopes)
  .AddMicrosoftGraph(configuration.GetSection("Authentication:DownstreamApi"))
  .AddInMemoryTokenCaches();

  // Require an authenticated user
  //services.AddControllersWithViews(options =>
  //{
  //    var policy = new AuthorizationPolicyBuilder()
  //        .RequireAuthenticatedUser()
  //        .Build();
  //    options.Filters.Add(new AuthorizeFilter(policy));
  //});

  //services
  //    // Add Razor Pages support
  //    .AddRazorPages()

  //    // Add Microsoft Identity UI pages that provide user 
  //    .AddMicrosoftIdentityUI();

  services.AddScoped&lt;GraphProfileClient&gt;();
  services.AddScoped&lt;GraphEmailClient&gt;();
  //services.AddScoped&lt;GraphCalendarClient&gt;();
  //services.AddScoped&lt;GraphFilesClient&gt;();

Hi @Bernard

I downloaded and ran the application, and I did not encounter any errors. I have no idea where the error is or how it occurred. Can you tell me which page I need to open and where I need to click so that I can see the error you saw in the logs?

Hi,

You need to go to after login like a tenant with OpenIdConnect

m.aliozkaya created 4 months ago

Hi @Bernard,

Please replace this code at Startup.cs line 385

     endpoints.MapFallbackToPage("/_Host");

     endpoints.MapRazorPages();

And I also recommend adding Area attribute for ElsaDashboardController

    [Area("App")]
    public class ElsaDashboardController : ERUDYControllerBase
    {
        public IActionResult Index()
        {
            return View();
        }
    }

I hope this helps. If the problem persists, please let us know.

Hi @Bernard,

The reason why the mail page was not working was related to this and now the mail page should be working. I will take a look for js issues about Elsa.
