Hi,
Our application is deployed in Azure, and we’d like to connect to both Azure Redis Cache and Azure Service Bus using Managed Identity for secure, secretless authentication. Does ABP.IO provide built-in support or configuration options for this scenario? If not, could you please guide us on how to implement this integration within an ABP.IO application?

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).
How to Integrate Managed Identity in ABP.IO
1. Azure Redis Cache
- Since StackExchange.Redis does not support managed identity, you must use a connection string with a key. If Microsoft adds managed identity support in the future, you could inject a custom IConnectionMultiplexer using Azure.Identity's DefaultAzureCredential, but this is not currently supported.
2. Azure Service Bus
- You can use Azure.Messaging.ServiceBus with DefaultAzureCredential for managed identity. In your ABP module, register the ServiceBusClient as a singleton:
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 allows your app to authenticate to Azure Service Bus using its managed identity.
3. General Guidance
- For both Redis and Service Bus, if/when the official client libraries support managed identity, you can override the default ABP service registrations to use your own client configuration.
- For now, Redis requires a connection string with a key, and Service Bus can use managed identity as shown above.

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 Microsoft.Azure.StackExchangeRedis package supports authentication via Managed Identity. Is there a way to override ABP.IO’s default cache connection configuration to leverage this package and connect securely to Azure Redis?

hi
You can add your Azure Redis connection string in
appsettings.json
, then Redis will automatically get and use it.See https://abp.io/docs/latest/framework/fundamentals/redis-cache#configuration
And you can use ABP Azure event bus.
See https://abp.io/docs/latest/framework/infrastructure/event-bus/distributed/azure Thanks.

Hi, We want to use managed identity to connect to redis not password.
configurationOptions = await ConfigurationOptions.Parse($"{cacheHostName}:6380").ConfigureForAzureWithUserAssignedManagedIdentityAsync(managedIdentityId!);
connectionMultiplexer = await ConnectionMultiplexer.ConnectAsync(configurationOptions);

hi
You can call the
context.Services.AddStackExchangeRedisCache(options =>
to override the defaultRedisCacheOptions
See https://github.com/abpframework/abp/blob/dev/framework/src/Volo.Abp.Caching.StackExchangeRedis/Volo/Abp/Caching/StackExchangeRedis/AbpCachingStackExchangeRedisModule.cs#L21-L28
Thanks.

Can you please provide an example of how to configure DefaultAzureCredential?

hi
Override the
ConfigureServicesAsync
of your startup module.Then move all code from
ConfigureServices
toConfigureServicesAsync
Then create and configure the
configurationOptions
, and finally set it toAddStackExchangeRedisCache
.public override async Task ConfigureServicesAsync(ServiceConfigurationContext context) { //... var configurationOptions = ConfigurationOptions.Parse("Your_RedisConnectionString"); await configurationOptions.ConfigureForAzureWithTokenCredentialAsync(new DefaultAzureCredential()); context.Services.AddStackExchangeRedisCache(options => { options.Configuration = null; options.ConfigurationOptions = configurationOptions; }); //... }
Thanks.
