To use TenantId as part of a composite key in an ABP entity, you must consider that EF Core does not allow nullable properties in primary keys. Since IMultiTenant.TenantId is nullable (to support host entities), making it part of a composite key will cause issues when TenantId is null (i.e., for host-owned entities).
If you define your entity as:
public class MyEntity : Entity, IMultiTenant
{
public Guid? TenantId { get; set; }
public Guid EntityId { get; set; }
public override object[] GetKeys()
{
return new object[] { TenantId, EntityId };
}
}
You will encounter problems saving entities with a null TenantId, because EF Core does not support nullable columns in primary keys.
Workarounds:
Example:
public class MyEntity : Entity<Guid>, IMultiTenant
{
public Guid? TenantId { get; set; }
// EntityId is now the primary key (from Entity<Guid>)
}
// In your DbContext:
protected override void OnModelCreating(ModelBuilder builder)
{
base.OnModelCreating(builder);
builder.Entity<MyEntity>()
.HasIndex(e => new { e.TenantId, e.Id })
.IsUnique();
}
This approach allows TenantId to be nullable and still enforces uniqueness for (TenantId, EntityId) without violating EF Core's primary key constraints.

To resolve the "This server only accepts HTTPS requests" error from OpenIddict when running your ABP AuthServer behind Nginx on Linux, you need to explicitly disable the HTTPS requirement in your configuration. By default, OpenIddict enforces HTTPS for security, but in reverse proxy scenarios (like Nginx terminating SSL), your backend app only sees HTTP traffic.
Solution:
In your appsettings.json, set:
"AuthServer": {
"Authority": "https://auth.mysite.it",
"RequireHttpsMetadata": "false",
"SwaggerClientId": "WebGateway_Swagger"
}
In your AuthServer module, add the following configuration to disable the transport security requirement when RequireHttpsMetadata is false:
if (!Convert.ToBoolean(configuration["AuthServer:RequireHttpsMetadata"]))
{
Configure<OpenIddictServerAspNetCoreOptions>(options =>
{
options.DisableTransportSecurityRequirement = true;
});
}
Ensure your Nginx is correctly forwarding headers (X-Forwarded-Proto) so that ABP/OpenIddict can detect the original HTTPS scheme.
Note: The Authority should still be set to your public HTTPS URL (https://auth.mysite.it). Disabling the HTTPS requirement only affects backend validation, not the public endpoints.
Reference Implementation: https://abp.io/docs/latest/solution-templates/layered-web-application/deployment/openiddict-deployment
Summary:
"RequireHttpsMetadata": "false" in your config.DisableTransportSecurityRequirement code in your AuthServer.This will allow your OpenIddict endpoints (like /.well-known/jwks) to be accessible behind a reverse proxy using HTTPS, even though your backend listens on HTTP.

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:
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);
}
}
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>()
);
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.
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.

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:
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.
Use a shared Identity and Tenant Management service:
Isolate permissions, localization, and audit logs:
UI and API separation:
Multi-tenancy:
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:
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.
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.
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.
If you see errors like SecurityTokenSignatureKeyNotFoundException or IDX10503 in logs, it indicates a certificate/key mismatch.
For local development, ensure both applications use the same domain or set up proper CORS and SameSite cookie policies.
If you are using HTTPS, ensure your certificates are trusted and valid for both domains.

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:
Upload the Certificate to Azure App Service:
.pfx certificate here.Configure Azure to Load the Certificate:
WEBSITE_LOAD_CERTIFICATES application setting to * (or the thumbprint of your certificate) in the App Service's "Configuration" > "Application settings".Load the Certificate from the Azure Certificate Store:
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];
<YOUR_CERT_THUMBPRINT> with your certificate's thumbprint.Use the Certificate in OpenIddict:
options.AddSigningCertificate(cert);
Important Notes:
X509KeyStorageFlags.MachineKeySet or file-based loading in Azure App Service, as the app may not have the required permissions.References:
