  • In ABP microservice or separated AuthServer scenarios, the [Authorize] attribute with a permission name (e.g., [Authorize("Permission.View")]) depends on correct claim propagation and permission definition registration across all relevant modules.

  • If _permissionChecker.IsGrantedAsync("Permission.View") returns true but [Authorize("Permission.View")] returns 403, the most common causes are:

    1. The permission is not defined or registered in the API module (the PermissionDefinitionProvider is missing or not referenced).
    2. Claims mapping or claim type configuration is inconsistent between AuthServer and the API module.
    3. The AbpClaimTypes are being updated by IdentityServer integration, which can break permission checks in microservices.

  • In microservice solutions, you must ensure:

    • The PermissionDefinitionProvider for "Permission.View" is referenced in the API module (typically via Application.Contracts).
    • The API module does not override or change claim types unexpectedly. If using IdentityServer, you may need to disable claim type updates in the API module:

  public override void PreConfigureServices(ServiceConfigurationContext context)
      {
          context.Services.PreConfigure<AbpIdentityServerBuilderOptions>(options =>
          {
              options.UpdateAbpClaimTypes = false;
          });
      }
  

  • Also, verify that the API module references the correct Application.Contracts and PermissionDefinitionProvider, and that the permission is visible in the Permission Management UI for the API service.

  • If the permission is only defined in the AuthServer, the API module will not recognize it for [Authorize] checks.

  hi

  When using [Authorize("Permission.View")] on API method, a user that has the "Permission.View" permission granted and on correct tenant, does not get Authorized and I get a 403 error.

  Can you add a custom middleware and share full debug logs?

  liming.ma@volosoft.com

  see https://abp.io/support/questions/8622/How-to-enable-Debug-logs-for-troubleshoot-problems

  var loggerConfiguration = new LoggerConfiguration()
      .MinimumLevel.Debug()
      .MinimumLevel.Override("Microsoft.EntityFrameworkCore", LogEventLevel.Warning)
      .Enrich.FromLogContext()
      .WriteTo.Async(c => c.File("Logs/logs.txt"))
  

  app.UseAuthentication();
  
  app.Use(async (httpContext, next) =>
  {
      var logger = httpContext.RequestServices.GetRequiredService<ILogger<YourModule>>();
      var claims = httpContext.User.Claims.Select(x => new { x.Type, x.Value }).ToList();
      logger.LogError("HttpContext.User Claims:");
      logger.LogError(JsonSerializer.Serialize(claims));
  
      var currentUser = httpContext.RequestServices.GetRequiredService<ICurrentUser>().GetAllClaims().Select(x => new { x.Type, x.Value }).ToList();
      logger.LogError("Current User Claims:");
      logger.LogError(JsonSerializer.Serialize(currentUser));
  
  
      var userid = AbpClaimTypes.UserId;
      var username = AbpClaimTypes.UserName;
      var roleClaimType = AbpClaimTypes.Role;
  
      logger.LogError($"UserId Claim Type: {userid}");
      logger.LogError($"UserName Claim Type: {username}");
      logger.LogError($"Role Claim Type: {roleClaimType}");
  
      var authorizationHeader = httpContext.Request.Headers["Authorization"];
      logger.LogError(!string.IsNullOrEmpty(authorizationHeader)
          ? $"Authorization Header: {authorizationHeader}"
          : "Authorization Header is missing or empty.");
  
      await next(httpContext);
  });
