• The issue of SQL connections remaining idle and not being released in the connection pool during high usage of /Account/ResetPassword is typically related to improper disposal of DbContext or uncompleted Unit of Work (UoW) scopes in ABP-based applications.

• In ABP, database connections are managed by the Unit of Work system. If a UoW is not completed or disposed properly (for example, due to an unawaited async call, an exception, or a long-running operation that never finishes), the underlying DbContext and its SQL connection may remain open, causing connection pool exhaustion.

• To prevent this issue:

  1. Ensure all application service and controller methods that interact with the database are async and properly awaited.
  2. Never block on async code (e.g., avoid .Result or .Wait() on async methods).
  3. Always complete or dispose the Unit of Work. In ABP, this is handled automatically for application services and controllers, but custom UoW usage (e.g., IUnitOfWorkManager.Begin()) must be completed with await uow.CompleteAsync().
  4. Check for any custom middleware, filters, or background jobs that might be holding onto DbContext or UoW instances longer than necessary.
  5. Review your code for any exceptions that might prevent UoW completion, especially in the password reset flow.

• For more details, see:

  • ABP Entity Framework Core Connection Management
  • ABP Unit of Work Documentation
  • Example of a related password reset flow and tenant handling: ABP Support: Reset password - Invalid token

• If you have custom code in your password reset logic (such as custom UoW or DbContext usage), ensure it follows the above best practices. If the problem persists, consider enabling detailed logging for UoW and DbContext lifetimes to identify where connections are not being released.

To install the ABP Studio CLI on Ubuntu, use the following command:

dotnet tool install -g Volo.Abp.Studio.Cli

If you encounter the error:

The settings file in the tool's NuGet package is invalid: Settings file 'DotnetToolSettings.xml' was not found in the package.
Tool 'volo.abp.studio.cli' failed to install.

This typically indicates a problem with the NuGet cache or a corrupted/incomplete package download. To resolve this:

1. Clear the NuGet cache:

dotnet nuget locals all --clear

2. Try installing the tool again:

dotnet tool install -g Volo.Abp.Studio.Cli

If the issue persists, ensure your NuGet.config does not reference any custom or private package sources that might interfere with the official package from nuget.org.

For more details, see the official ABP CLI installation documentation.

The %%entity-namespace%% and %%microservice-entities-namespace-prefix%% template variables in ABP Suite are calculated based on the entity's location and the project structure. In recent ABP Suite versions (including 1.2.2 and ABP 9.3.x), there was a fix to make these namespace calculations more accurate and consistent, especially for microservice solutions.

• The value for %%entity-namespace%% is now derived from the actual folder structure of your entity files. For example, if your entity is under Entities\BtaApiShop\DetailMappings, the namespace will be ...Entities.BtaApiShop.DetailMappings.
• The value for %%microservice-entities-namespace-prefix%% is also based on the folder path and project root, ensuring that generated code matches the physical structure.

You can see these values in the generated code and in the .json files under the suite/entities folder. If you want to adjust or review how these are set:

• Open the relevant entity's .json file in suite/entities.
• The namespace is determined by the "Namespace" property, which is auto-calculated by ABP Suite based on the entity's folder.

If you have custom requirements for namespaces, you will need to manually adjust the folder structure or the generated code after using ABP Suite, as the calculation is now standardized and not user-configurable from the UI.

This change was made to fix inconsistencies and ensure that generated code compiles correctly with the expected namespaces.

• The error "DbMigrator is not found!" indicates that the ABP CLI or Studio could not locate the DbMigrator project in your solution. This typically happens if the DbMigrator project is missing, not built, or not referenced correctly in your solution.

How to resolve:

1. Ensure the DbMigrator project exists in your solution directory.
2. Make sure the project is included in your solution file (.sln). If not, right-click the solution in Visual Studio and add the existing project.
3. Build the entire solution to ensure the DbMigrator executable is generated.
4. If you renamed or moved the DbMigrator project, update all references and paths accordingly.
5. Run the DbMigrator either from the command line or directly from Visual Studio as documented.

# Example: Run from command line
dotnet run --project path/to/YourProject.DbMigrator

To enable your Blazor Web App to log in using your custom OpenIddict grant type (e.g., "employee_number"), you need to customize the authentication flow to request a token from the AuthServer using your custom grant. The Blazor template uses OpenID Connect by default, but you can perform a direct token request using HTTP.

Here’s how you can implement OTP login with your custom grant in a Blazor Web App:

1. Expose the Custom Grant on AuthServer

   • Ensure your AuthServer is configured to accept the "employee_number" grant type and that the client (Blazor app) has permission for this grant.

2. Create a Service in Blazor to Request the Token

   • Use HttpClient to POST to /connect/token with the required parameters.

   Example service:

public class OtpLoginService
   {
       private readonly HttpClient _httpClient;

       public OtpLoginService(HttpClient httpClient)
       {
           _httpClient = httpClient;
       }

       public async Task<TokenResponse> LoginWithEmployeeNumberAsync(string employeeNumber, string timestamp, string signature)
       {
           var parameters = new Dictionary<string, string>
           {
               { "grant_type", "employee_number" },
               { "employee_number", employeeNumber },
               { "timestamp", timestamp },
               { "signature", signature },
               { "client_id", "<YourClientId>" },
               { "client_secret", "<YourClientSecret>" }, // if required
               { "scope", "profile roles email phone offline_access master9" }
           };

           var content = new FormUrlEncodedContent(parameters);
           var response = await _httpClient.PostAsync("https://<auth-server-url>/connect/token", content);

           response.EnsureSuccessStatusCode();
           var json = await response.Content.ReadAsStringAsync();
           return JsonSerializer.Deserialize<TokenResponse>(json);
       }
   }

   public class TokenResponse
   {
       public string access_token { get; set; }
       public string token_type { get; set; }
       public int expires_in { get; set; }
       public string refresh_token { get; set; }
   }

3. Store and Use the Token in Blazor

   • After receiving the token, store it (e.g., in local storage) and update the authentication state.
   • You may need to implement a custom AuthenticationStateProvider to use the token for authenticated API calls.

4. Trigger the Login Flow

   • Call your OtpLoginService.LoginWithEmployeeNumberAsync from your Blazor login page/component when the user submits their OTP.

5. Update the Authentication State

   • After a successful login, update the authentication state so the Blazor app recognizes the user as logged in.

Note: The default Blazor OIDC authentication flow does not support custom grant types out-of-the-box. You must handle the token acquisition and authentication state update manually as shown above.

• Validated: How to add a custom grant type in OpenIddict (ABP Community)

This approach aligns with common ABP and OpenIddict extension grant usage for custom authentication scenarios.

This response was generated by AI. If it didn’t solve your problem, feel free to post a new answer — our support team will jump in to help you soon.

To get an auth token for a logged-in user in an ABP app service (without username/password and without posting to /connect/token in the usual way), you need to implement a custom OpenIddict grant type. This allows you to issue tokens programmatically for a user who is already authenticated in your backend logic.

Steps:

1. Implement a Custom Grant Type
   • Create a class implementing ITokenExtensionGrant (e.g., MyTokenExtensionGrant).
   • In your HandleAsync method, validate the current user context and generate a token for that user.

public class MyTokenExtensionGrant : ITokenExtensionGrant
   {
       public const string ExtensionGrantName = "my_custom_grant";
       public string Name => ExtensionGrantName;

       public async Task<IActionResult> HandleAsync(ExtensionGrantContext context)
       {
           // Validate and get the user (e.g., from context)
           var userManager = context.HttpContext.RequestServices.GetRequiredService<IdentityUserManager>();
           var user = await userManager.FindByNameAsync("admin"); // Replace with your logic

           var userClaimsPrincipalFactory = context.HttpContext.RequestServices.GetRequiredService<IUserClaimsPrincipalFactory<IdentityUser>>();
           var claimsPrincipal = await userClaimsPrincipalFactory.CreateAsync(user);

           // Set scopes/resources as needed
           claimsPrincipal.SetScopes(new[] { "AbpAPI", "profile" });
           claimsPrincipal.SetResources(new[] { "AbpAPI" });

           return new SignInResult(OpenIddictServerAspNetCoreDefaults.AuthenticationScheme, claimsPrincipal);
       }
   }

2. Register the Grant Type
   • In your module, register the grant type with OpenIddict and ABP:

PreConfigure<OpenIddictServerBuilder>(builder =>
   {
       builder.Configure(options =>
       {
           options.GrantTypes.Add(MyTokenExtensionGrant.ExtensionGrantName);
       });
   });

   Configure<AbpOpenIddictExtensionGrantsOptions>(options =>
   {
       options.Grants.Add(MyTokenExtensionGrant.ExtensionGrantName, new MyTokenExtensionGrant());
   });

3. Add Grant Type Permission to Client

   • Update your OpenIddict client (application) to allow the new grant type in its permissions.

4. Request Token Using the Custom Grant

   • From your backend, you can now request a token for the user using the custom grant type, without needing their password.

This approach is the recommended and secure way to issue tokens for already-authenticated users in ABP, without exposing or requiring their credentials.

The error message in your screenshot indicates an issue with the OpenID Connect discovery document, specifically: "error validating authorization_endpoint in discovery document ['https for all urls required. Also for urls received by discovery.']". This means that all URLs in your OpenIddict/OpenID Connect configuration must use HTTPS, and any endpoints returned by the discovery document must also be HTTPS.

This is a common issue when deploying ABP microservice solutions to Kubernetes or other environments where HTTPS is enforced.

Steps to resolve:

1. Ensure all URLs in your appsettings and environment variables use HTTPS, not HTTP. This includes:

   • AuthServer:Authority
   • AuthServer:MetaAddress
   • IdentityClients:Default:Authority
   • RemoteServices:...:BaseUrl

2. Make sure your Kubernetes ingress/controller is configured to serve HTTPS and that your certificates are valid.

3. In your OpenIddict server configuration, set the issuer to the correct HTTPS URL:

PreConfigure<OpenIddictServerBuilder>(builder =>
   {
       builder.SetIssuer(new Uri(configuration["AuthServer:Authority"])); // Should be HTTPS
   });

4. If you are using self-signed certificates for local development, ensure your browser trusts them. For production, use a valid certificate authority.

5. After making these changes, clear your browser cache and tokens.

For more details and troubleshooting steps, see:

• ABP Support: Angular Front-End Redirect Auth Issue Kubernetes Deployment
• ABP Support: Angular Front-End Redirect Auth Issue Kubernetes Deployment (related)

These steps should resolve the "https for all urls required" error and allow your ABP Angular application to authenticate correctly in Kubernetes.

• The error "Failed to refresh remote claims for user" from Volo.Abp.AspNetCore.Authentication.JwtBearer.DynamicClaims.WebRemoteDynamicClaimsPrincipalContributorCache typically indicates a problem with ABP's dynamic claims feature when running in a distributed environment like Azure Kubernetes Service (AKS).

• ABP's dynamic claims feature is designed to update user claims in real-time without requiring re-authentication. It works by making remote HTTP calls to refresh claims. If these calls fail (e.g., due to network issues, service discovery problems, or authorization failures), you will see such errors and possibly 401 responses.

• Common causes and solutions:

  1. Service-to-service authentication/authorization issues: Ensure that all microservices can securely call each other's endpoints required for dynamic claims. In AKS, check your internal networking, service discovery, and authentication configuration.
  2. Token expiration or invalid tokens: If the access token used for the remote call is expired or invalid, the remote service will return 401. Make sure token lifetimes and clock synchronization are correct across your services.
  3. Dynamic claims configuration: If you do not require real-time claim updates, you can disable dynamic claims to avoid these errors. Remove or set IsDynamicClaimsEnabled = false in your configuration:

context.Services.Configure<AbpClaimsPrincipalFactoryOptions>(options =>
     {
         options.IsDynamicClaimsEnabled = false;
     });

4. Pipeline configuration: If you use app.UseDynamicClaims() in your service startup, ensure it is only enabled where needed (typically in the Web and AuthServer projects, not in all microservices).

• For more details and troubleshooting, see:

  • ABP Dynamic Claims Documentation
  • ABP Support: Dynamic Claims 401/500 Errors

• If you do need dynamic claims, ensure all services are properly configured for secure internal HTTP communication and that tokens are valid and not expired during inter-service calls.

• The message you are seeing is displayed by the free version of the Blazorise component library starting from certain versions. This is a new behavior introduced by Blazorise to encourage commercial licensing for professional or commercial use.
• After updating to Blazorise 1.8.2, this notification is now shown by default in applications that do not use a commercial Blazorise license. This is not controlled by ABP, but by Blazorise itself.
• In previous versions, this message was not present, which is why you did not see it before the update.

To remove or suppress this message:

• You must purchase a commercial license for Blazorise and configure your application to use the commercial license key as described in the Blazorise documentation.
• There is no supported or legal way to suppress this message in the free version for commercial/professional use.

If you wish to restore the previous behavior (no message), you would need to downgrade to a Blazorise version before this change, but this is not recommended or supported for long-term projects.
