To enable a feature such as FAQ for the Host tenant in ABP, follow these steps:
Troubleshooting Steps:
FeatureDefinitionProvider implementation.Example: Registering a Feature
public class MyFeatureDefinitionProvider : FeatureDefinitionProvider
{
public override void Define(IFeatureDefinitionContext context)
{
context.Add(new FeatureDefinition(
"App.FAQ",
defaultValue: "false",
displayName: "FAQ Feature",
description: "Enables the FAQ module."
));
}
}
After registering, you should see the FAQ feature in the features modal.
If the modal is empty or the feature does not appear:
If you see a specific error in the console:

ABP Framework does not provide built-in, out-of-the-box support for connecting to Azure Redis Cache or Azure Service Bus using Azure Managed Identity. The standard Redis and Service Bus integrations in ABP rely on connection strings (secrets) rather than managed identity authentication.
For Redis, ABP uses the Volo.Abp.Caching.StackExchangeRedis package, which is an extension of Microsoft.Extensions.Caching.StackExchangeRedis. As of now, the underlying StackExchange.Redis client does not natively support Azure Managed Identity authentication; it expects a connection string with a key.
For Azure Service Bus, ABP does not provide a built-in module. If you use Azure.Messaging.ServiceBus or Microsoft.Azure.ServiceBus, you can configure these libraries to use Azure Managed Identity by providing a TokenCredential (e.g., DefaultAzureCredential from Azure.Identity).
using Azure.Identity;
using Azure.Messaging.ServiceBus;
public override void ConfigureServices(ServiceConfigurationContext context)
{
context.Services.AddSingleton<ServiceBusClient>(provider =>
{
var fullyQualifiedNamespace = "<your-service-bus-namespace>.servicebus.windows.net";
var credential = new DefaultAzureCredential();
return new ServiceBusClient(fullyQualifiedNamespace, credential);
});
}

This approach aligns with common ABP conventions, but specific official documentation for managed identity with Redis or Service Bus in ABP is not available.

The slowness in dynamic claims contributors like EditionDynamicClaimsPrincipalContributor and IdentitySessionDynamicClaimsPrincipalContributor is typically due to expensive operations (such as database queries or remote service calls) being performed on every HTTP request, since dynamic claims are resolved for every request and user.
According to ABP documentation, it is strongly recommended to use caching inside your dynamic claims contributors to avoid performance bottlenecks. The ContributeAsync method is called very frequently, so any non-cached logic (such as fetching edition or session data from the database) will cause significant delays.
For contributors like EditionDynamicClaimsPrincipalContributor, you should cache the edition information per tenant, as editions rarely change. For session-related contributors, cache the session data per user/session as appropriate.
Example (pseudo-code for caching inside a contributor):
public class MyDynamicClaimsContributor : IAbpDynamicClaimsPrincipalContributor
{
private readonly IDistributedCache<MyEditionInfo> _cache;
private readonly IEditionRepository _editionRepository;
public MyDynamicClaimsContributor(IDistributedCache<MyEditionInfo> cache, IEditionRepository editionRepository)
{
_cache = cache;
_editionRepository = editionRepository;
}
public async Task ContributeAsync(AbpDynamicClaimsPrincipalContributorContext context)
{
var tenantId = context.Principal.FindFirstValue(AbpClaimTypes.TenantId);
var cacheKey = $"edition-info:{tenantId}";
var editionInfo = await _cache.GetOrAddAsync(
cacheKey,
async () => await _editionRepository.GetEditionInfoAsync(tenantId),
() => new DistributedCacheEntryOptions { AbsoluteExpirationRelativeToNow = TimeSpan.FromHours(1) }
);
// Add claims using editionInfo...
}
}
Review your dynamic claims contributors and ensure all expensive operations are cached. If you are using ABP's built-in contributors, check if you have disabled or misconfigured distributed cache (e.g., Redis) in your environment, as this will force contributors to hit the database every time.
For further optimization, profile your contributors to identify any unnecessary or repeated queries, and refactor to minimize work done per request.

The error message Volo.Authorization:010001 ("Authorization failed! Given policy has not granted.") typically means the current user or token does not have the required permissions for the API endpoint being accessed.
If your refresh token is expiring or being revoked, and tokens are cleared every time you request an API, this is often related to authentication or cookie/session issues, especially in browser-based applications.

This issue occurs when impersonating a user from the Host (no tenant) and then using the "Login as this tenant" action in the SaaS module, resulting in an "Access Denied" error. However, after navigating back or clearing the URL, the impersonation works as expected.
This behavior is related to the impersonation and tenant switching flow in ABP 9.3.2. In recent ABP versions, some changes in authentication and tenant context handling may cause the impersonation state or permissions to not be fully refreshed when switching tenants, especially in Blazor Server and tiered setups.
Workarounds and checks:

Your issue is caused by the OpenID Connect discovery document returning HTTP endpoints (e.g., "authorization_endpoint": "http://authserver.mydomain.dev/connect/authorize") instead of HTTPS, while your clients and security libraries require all endpoints to use HTTPS.
This typically happens when your AuthServer is running behind a reverse proxy (like ingress-nginx in AKS), and the application itself is listening on HTTP. OpenIddict (or IdentityServer) generates endpoint URLs based on the incoming request's scheme, which is HTTP unless you explicitly handle forwarded headers.
Solution:
Forwarded Headers Middleware
In your AuthServer's Startup or module initialization, add the following before any authentication middleware:
app.UseForwardedHeaders(new ForwardedHeadersOptions
{
ForwardedHeaders = ForwardedHeaders.XForwardedProto | ForwardedHeaders.XForwardedFor,
// Optionally, set KnownProxies or KnownNetworks if needed for security
});
This ensures the app recognizes the original HTTPS scheme from the proxy.
Force HTTPS Scheme (if needed)
If the above does not resolve the issue, you can force the request scheme to HTTPS as a workaround:
app.Use(async (ctx, next) =>
{
ctx.Request.Scheme = "https";
await next();
});
Place this middleware before authentication and OpenIddict middlewares.
Set OpenIddict Issuer Explicitly
In your AuthServer module, ensure you set the issuer to your public HTTPS URL:
PreConfigure<OpenIddictServerBuilder>(builder =>
{
builder.SetIssuer(new Uri(configuration["AuthServer:Authority"]!));
});
Check NGINX/Ingress Configuration
Make sure your ingress-nginx is forwarding the X-Forwarded-Proto header and not stripping it.
Restart and Test
After making these changes, restart your AuthServer pod and check the discovery document at https://authserver.mydomain.dev/.well-known/openid-configuration. All endpoints should now use HTTPS.
References:
This approach is the recommended and secure way to ensure your OpenIddict endpoints are correctly exposed as HTTPS behind a reverse proxy in Kubernetes.

The style loading order issue you are experiencing after upgrading to ABP 9.3.2 is a known problem that can affect how custom styles and third-party styles (like ngx-datatable) are applied, especially with the Lepton (non-X) theme.
In ABP Angular projects, the order of styles in the generated HTML is determined by the order in the angular.json file's "styles" array. If styles.css is loaded before third-party styles (like ngx-datatable), your overrides may not work as expected.
To resolve this, ensure that your angular.json lists the styles in the correct order. For your scenario, you should place your styles.css after all third-party and theme styles, for example:
"styles": [
"src/styles/lepton4.css",
"src/styles/ngx-datatable-index.css",
"src/styles/ngx-datatable-icons.css",
"src/styles/ngx-datatable-material.css",
"src/styles/fontawesome-all.min.css",
"src/styles/fontawesome-v4-shims.min.css",
"src/styles/styles.css"
]
This ensures that your custom styles in styles.css are loaded last and can override previous styles.
After making this change, rebuild your Angular project to ensure the new order is reflected in the output HTML.
If you are using ABP's dynamic style injection or any runtime style loader, make sure it does not alter the intended order.
For more details and a similar issue (with LeptonX, but the principle applies), see:
This approach should resolve the style override issues with ngx-datatable and other components after your ABP upgrade.

To resolve the CORS error when accessing the OpenID configuration endpoint from your frontend, you need to ensure that the backend (on port 1661) is configured to allow cross-origin requests from your frontend (on port 1660). In ABP-based applications, this is typically managed via the CorsOrigins setting and middleware configuration.
Steps to fix:
appsettings.json on the backend (port 1661):
Make sure the CorsOrigins property includes your frontend's origin. For your scenario:"App": {
"CorsOrigins": "http://serverName:1660"
}
OnApplicationInitialization method, ensure you have:app.UseCors();
app.UseAuthentication() and app.UseAuthorization().Restart the backend application after making these changes.
If using IIS, no additional IIS-specific CORS configuration is needed if the ABP CORS middleware is active and correctly configured.
Verify: After deployment, use browser dev tools to check that the Access-Control-Allow-Origin header is present in responses from https://serverName:1661/.well-known/openid-configuration when requested from your frontend.
Note: If you are using a reverse proxy or load balancer, ensure it does not strip CORS headers.

In ABP, when a feature (such as Identity.MaxUserCount) is set at the edition level, it cannot be overridden at the tenant level for tenants assigned to that edition. This is by design and confirmed in the referenced post.
To allow a higher user count for a specific tenant, the recommended and supported approach is to create a new edition with the desired feature value and assign this edition to the tenant. This way, you can customize the feature for that tenant without affecting others.
If the edition selection is disabled in the UI due to an active subscription, directly changing the edition in the database is not recommended. Doing so can lead to inconsistencies, especially with the SaaS module's subscription and renewal logic, which expects the edition and subscription data to be in sync. Manual changes may break renewal, billing, or feature assignment processes.
The best practice is to use the official APIs or UI to manage editions and subscriptions. If you need to change the edition for a tenant with an active subscription, consider:
Direct database manipulation is not supported and may cause unexpected issues with the SaaS module.

Example:
public override async Task<ListResultDto<string>> GetTwoFactorProvidersAsync()
{
// Only return TOTP provider
return new ListResultDto<string>(new List<string> { "Authenticator" });
}
Make sure your UI only displays the TOTP option and does not require email or phone verification for enabling TOTP.
You may need to customize the authentication flow in your Angular app to handle this redirect. Typically, after login, if the backend indicates that 2FA is required (e.g., via a specific response or claim), perform a client-side redirect:
// Pseudocode for Angular
if (userRequires2FA) {
this.router.navigate(['/account/manage']);
}
Ensure your backend enforces 2FA when required and that the Angular app checks for this state after authentication.
