To deactivate the automatic creation of LDAP users in ABP (Account Pro module), you need to override the default behavior of the LDAP external login provider. By default, ABP will attempt to create a new user if one does not exist when authenticating via LDAP. Since you want to handle user creation yourself and prevent ABP from creating users automatically, you should override the relevant service and suppress the user creation logic.

Here’s how you can achieve this:

1. Override the LdapExternalLoginProvider
   Create a custom class that inherits from LdapExternalLoginProvider and override the CreateUserIfNotExistsAsync method to prevent user creation.

   using Volo.Abp.Identity.Pro.Ldap;
   using Volo.Abp.Identity.ExternalLoginProviders;
   using System.Threading.Tasks;
   
   public class MyLdapExternalLoginProvider : LdapExternalLoginProvider
   {
       public MyLdapExternalLoginProvider(
           // inject required dependencies
       ) : base(
           // pass dependencies to base
       )
       {
       }
   
       protected override Task<ExternalLoginUserInfo> CreateUserIfNotExistsAsync(
           string userName, 
           string providerName, 
           ExternalLoginUserInfo externalUser)
       {
           // Prevent automatic user creation
           // Optionally, throw a custom exception or return null
           return Task.FromResult<ExternalLoginUserInfo>(null);
       }
   }
   

2. Register Your Custom Provider
   In your module’s ConfigureServices method, replace the default service with your custom implementation:

   context.Services.Replace(
       ServiceDescriptor.Transient<LdapExternalLoginProvider, MyLdapExternalLoginProvider>()
   );
   

3. Handle User Creation Manually
   You can now create users manually in your own logic (e.g., in TryAuthenticateAsync). Since the overridden method returns null, ABP will not attempt to create the user again, and you will avoid the duplicate user creation error.

4. Error Handling
   If you want to provide a user-friendly error when a user does not exist, you can throw a UserFriendlyException in your override.

Note: The actual class and method names may vary depending on your ABP version. The key is to override the method responsible for user creation and ensure it does not create users automatically.

To add space between the Search and Filter buttons in the Tenants page, you can use custom CSS. This is a common UI adjustment and can be achieved by adding a margin to the button elements. For example, you can add the following CSS to your global styles (e.g., global-styles.css):

/* Add space between search and filter buttons */
.tenant-search-form .btn + .btn {
    margin-left: 0.5rem;
}

If your buttons are not wrapped in a specific class, you can target them more generally or add a custom class to the button group for more precise control.

After adding the CSS, the buttons will have the desired spacing between them.

To set up CI/CD with GitHub Actions for deploying your ABP-based Web and public.web apps to Azure App Services, and to resolve the package restore errors you encountered, follow these steps:

1. Ensure Your NuGet Sources Are Correct

• ABP Commercial packages (like Volo.Abp.Identity.Pro.HttpApi, Volo.Saas.Domain, etc.) are not available on nuget.org. You must add your ABP Commercial NuGet source (https://nuget.abp.io/...) with your license key in your NuGet.config.
• Example NuGet.config:

  <?xml version="1.0" encoding="utf-8"?>
  <configuration>
    <packageSources>
      <add key="nuget.org" value="https://api.nuget.org/v3/index.json" />
      <add key="abp-commercial" value="https://nuget.abp.io/[YOUR_ORG_ID]/v3/index.json" />
    </packageSources>
    <packageSourceCredentials>
      <abp-commercial>
        <add key="Username" value="your-email@example.com" />
        <add key="ClearTextPassword" value="[YOUR_ABP_LICENSE_KEY]" />
      </abp-commercial>
    </packageSourceCredentials>
  </configuration>
  

• Make sure this file is present in your repository root and referenced in your GitHub Actions workflow.

2. Remove Duplicate PackageReferences

• Edit your .csproj files to remove any duplicate <PackageReference> entries, especially for Volo.Saas.Domain.

3. Example GitHub Actions Workflow for ABP + Azure App Service

• Place this in .github/workflows/azure-webapp.yml:

  name: Build and deploy ASP.Net Core app to Azure Web App
  
  on:
    push:
      branches:
        - main
    workflow_dispatch:
  
  jobs:
    build:
      runs-on: ubuntu-latest
      steps:
        - uses: actions/checkout@v4
  
        - name: Setup .NET
          uses: actions/setup-dotnet@v4
          with:
            dotnet-version: '9.x'
            include-prerelease: true
  
        - name: Restore dependencies
          run: dotnet restore src/Tapp.Web/Tapp.Web.csproj --configfile NuGet.config
  
        - name: Build
          run: dotnet build src/Tapp.Web/Tapp.Web.csproj --configuration Release --no-restore
  
        - name: Publish
          run: dotnet publish src/Tapp.Web/Tapp.Web.csproj --configuration Release --output ./publish --no-build
  
        - name: Upload artifact
          uses: actions/upload-artifact@v4
          with:
            name: webapp
            path: ./publish
  
    deploy:
      runs-on: ubuntu-latest
      needs: build
      steps:
        - name: Download artifact
          uses: actions/download-artifact@v4
          with:
            name: webapp
            path: ./publish
  
        - name: Deploy to Azure Web App
          uses: azure/webapps-deploy@v3
          with:
            app-name: '<YOUR_AZURE_APP_NAME>'
            publish-profile: ${{ secrets.AZUREAPPSERVICE_PUBLISHPROFILE }}
            package: ./publish
  

• Store your Azure publish profile as a GitHub secret named AZUREAPPSERVICE_PUBLISHPROFILE.

4. Troubleshooting

• If you see errors like "Unable to find package ...", double-check your NuGet.config and ensure your ABP Commercial source and credentials are correct.
• For duplicate package warnings, clean up your .csproj files.

• In ABP applications, when running in the Development environment, detailed error messages (such as 401 Unauthorized) are shown by default. However, in the Production environment, ABP hides detailed error information and returns a generic 500 Internal Server Error for unhandled exceptions or unauthorized access, to avoid leaking sensitive information.

• This behavior is by design for security reasons. If you want to return proper status codes (like 401) in Production, ensure that your exception handling and authentication middleware are configured correctly, and that you are not catching and re-throwing exceptions as generic errors.

• Also, make sure your application is not exposing detailed errors in Production, as this is a security risk. The 500 error is a safe default.

To achieve a shared user and tenant base across multiple ABP microservice applications (such as CRM and ERP), while keeping permissions, localization, and audit logs separate per application, you should:

1. Upgrade all your services and modules to the same ABP version (e.g., 9.1.3). This is required for compatibility, especially for shared modules like Identity and Saas.

2. Use a shared Identity and Tenant Management service:

   • Both CRM and ERP applications should use the same Identity and Saas microservices for authentication and tenant resolution.
   • This ensures users and tenants are managed centrally and are accessible from both applications.

3. Isolate permissions, localization, and audit logs:

   • Each application (CRM, ERP) can define its own permissions, roles, and policies. ABP's permission system is modular and supports per-application configuration.
   • Localization resources can be separated by module or application, so each app can have its own translations.
   • Audit logging is also modular; each service can log its own actions independently.

4. UI and API separation:

   • Each application can have its own UI and API, with separate permission sets and features, but still rely on the central Identity and Tenant Management.

5. Multi-tenancy:

   • ABP's multi-tenancy system ensures that all data is tenant-scoped, and users are associated with tenants, regardless of which application they use.

This architecture is fully supported by ABP. You only need to ensure all services use the same Identity and Saas backends, and that all modules are upgraded to the same ABP version.

• When using a separated AuthServer and Blazor UI in ABP, the most common cause for the login state not being preserved after redirection is a misconfiguration in the OpenIddict certificate, client settings, or cookie/token handling between the two applications.

• Based on verified ABP support cases, here are the key points to check and resolve:

1. Ensure the OpenIddict signing certificate (e.g., openiddict.pfx) and its passphrase are identical and correctly configured in both the AuthServer and the Backend API. A mismatch or missing certificate will prevent token validation, causing the UI to not recognize the login state.

2. Double-check the client configuration in your AuthServer. The redirect_uri and post_logout_redirect_uri for your Blazor WebApp must exactly match the URLs used by your UI application.

3. If you cloned or deployed the solution, make sure the openiddict.pfx file is present in both projects and not ignored by source control or missing on the server.

4. If you see errors like SecurityTokenSignatureKeyNotFoundException or IDX10503 in logs, it indicates a certificate/key mismatch.

5. For local development, ensure both applications use the same domain or set up proper CORS and SameSite cookie policies.

6. If you are using HTTPS, ensure your certificates are trusted and valid for both domains.

Example fix (from verified ABP support):

• Sync the CertificatePassPhrase in both AuthServer and Backend API.
• Generate a new openiddict.pfx and copy it to both projects.
• Restart both applications.

Sources (validated):

• https://abp.io/support/questions/9274
• https://abp.io/support/questions/899
• https://abp.io/docs/latest/framework/ui/blazor/authentication

This approach is confirmed by ABP support and documentation for separated AuthServer scenarios.

To resolve the "System.Security.Cryptography.CryptographicException: Keyset does not exist" error when deploying an ABP-based API to Azure App Service, you need to ensure that the certificate is loaded in a way compatible with Azure's environment and permissions.

Solution Steps:

1. Upload the Certificate to Azure App Service:

   • In the Azure Portal, go to your App Service.
   • Navigate to "TLS/SSL settings" > "Private Key Certificates (.pfx)".
   • Upload your .pfx certificate here.

2. Configure Azure to Load the Certificate:

   • Set the WEBSITE_LOAD_CERTIFICATES application setting to * (or the thumbprint of your certificate) in the App Service's "Configuration" > "Application settings".

3. Load the Certificate from the Azure Certificate Store:

   • Instead of loading the certificate from a file, load it from the certificate store as shown below:

   using System.Security.Cryptography.X509Certificates;
   
   var store = new X509Store(StoreName.My, StoreLocation.CurrentUser);
   store.Open(OpenFlags.ReadOnly);
   var certs = store.Certificates
       .Find(X509FindType.FindByThumbprint, "<YOUR_CERT_THUMBPRINT>", false);
   
   if (certs.Count == 0)
       throw new Exception("Certificate not found in store.");
   
   var cert = certs[0];
   

   • Replace <YOUR_CERT_THUMBPRINT> with your certificate's thumbprint.

4. Use the Certificate in OpenIddict:

   • Pass the loaded certificate to OpenIddict as you did before.

   options.AddSigningCertificate(cert);
   

5. Important Notes:

   • Do not use X509KeyStorageFlags.MachineKeySet or file-based loading in Azure App Service, as the app may not have the required permissions.
   • Always ensure the certificate has a private key and is accessible by the App Service process.

To resolve the System.ArgumentOutOfRangeException from the AbpApplicationConfigurationScript endpoint after upgrading to ABP 9.2.1, follow these steps:

1. Check for Static Asset Middleware Changes

   • ABP 9.x and .NET 9 introduced changes in static asset delivery. Ensure you are using the correct middleware for static files. In your Startup.cs or program setup, replace:

     app.UseStaticFiles();
     

     with:

     app.MapAbpStaticAssets();
     

   • This is required for proper static asset handling in ABP 9.x. See the migration guide for details.

2. Review the Migration Guide

   • There are breaking changes in ABP 9.2.x. Review the official migration guide and ensure all required changes are applied:
     • Update all ABP NuGet and NPM packages to 9.2.1.
     • Check for any customizations or overrides in your solution that may affect static file or configuration script delivery.
     • Compare your production and staging environments for differences in static file configuration, file permissions, or deployment artifacts.

3. Clear and Rebuild Static Assets

   • Delete the wwwroot or equivalent static assets output directory and rebuild your solution to ensure all assets are up to date.
   • If you use a CDN or reverse proxy, clear its cache.

4. Check File System and Permissions

   • The error may occur if a static file is missing or has incorrect permissions. Verify that all files referenced by the application exist and are accessible by the application process.

5. Review Application Configuration Script Endpoint

   • The /Abp/ApplicationConfigurationScript endpoint provides configuration for SPA clients. If you have customizations or middleware affecting this endpoint, review them for compatibility with ABP 9.2.1.

6. Compare Environments

   • Since staging works but production fails, compare:
     • .NET SDK/runtime versions
     • File system structure and permissions
     • Environment variables and configuration files

7. Check for Known Issues

   • Review the ABP 9.2 migration guide and community articles for any known issues related to static asset delivery or the ApplicationConfigurationScript endpoint.

If the above steps do not resolve the issue, provide more details about custom middleware, deployment process, or any recent changes to static file handling.

• Using Global Features in ABP Framework is a recommended and clean approach for enabling or disabling parts of a module (such as permissions, endpoints, or services) based on the presence or activation of other modules. This pattern is specifically designed to allow modules to adapt their behavior without introducing tight coupling between them.
• By leveraging Global Features, you can conditionally register or expose functionality in your PPM module depending on whether MEX or OEX is enabled, as shown in your code example. This keeps your modules loosely coupled and maintains modularity, since the feature flags are managed centrally and do not require direct references between modules.
• This approach is documented and encouraged in the official ABP documentation for modularity and global features. It is preferable to alternatives such as hard dependencies or runtime type checks, which can lead to maintenance and upgrade issues.

If you need to further customize or override module behavior, you can also use the extensibility and customization mechanisms provided by ABP, such as service replacement or module extension points.

The Volo.Saas.Tenants.TenantManager.CreateAsync(string name, Nullable<Guid> editionId) method in ABP Commercial uses internal validation logic to ensure tenant names are valid and unique. The core of this validation is performed in the ValidateNameAsync method.

Here are the key validations performed by ValidateNameAsync:

1. Name Not Null or Empty: The tenant name must not be null, empty, or whitespace.
2. Name Length: The tenant name must not exceed the maximum allowed length (typically 64 characters, but this can be checked in your entity definition).
3. Name Uniqueness: The normalized tenant name must be unique. If another tenant already exists with the same normalized name (case-insensitive, trimmed, etc.), a BusinessException is thrown.
4. Name Format: The name may be checked for allowed characters (e.g., no whitespace or special characters), depending on your implementation or any customizations.
5. Custom Rules: If you have overridden the TenantManager or repository, you may have additional custom rules (e.g., removing whitespace, regex checks).

If any of these validations fail, a Volo.Abp.BusinessException is thrown, which is what you are seeing in your stack trace.

Example of a custom name validation (from community guidance):

public override async Task<Tenant> FindByNameAsync(string name, bool includeDetails = true, CancellationToken cancellationToken = default)
{
    var tenants = await (await GetDbSetAsync())
        .IncludeDetails(includeDetails)
        .OrderBy(t => t.Id).ToListAsync();

    return tenants
        .FirstOrDefault(t => (t.Name == name || TestUrlNamingConvention(t.Name, name)));
}

private bool TestUrlNamingConvention(string tenantName, string inputName)
{
    var i = string.Concat(inputName.Where(c => !char.IsWhiteSpace(c))).ToLowerInvariant();
    var t = string.Concat(tenantName.Where(c => !char.IsWhiteSpace(c))).ToLowerInvariant();
    return i == t;              
}

This shows how you can extend or customize the validation logic.

Summary:

• The default validations are: not null/empty, length, uniqueness, and possibly allowed characters.
• You can override or extend these by customizing the TenantManager or repository.
