- What is azure-oss/identity used for in Laravel?
- It is a PHP identity library for acquiring Microsoft Entra ID access tokens through flows such as client secret, client certificate, workload identity, managed identity, chained, and default credentials. Laravel apps use it when they need an OAuth2 bearer token for Azure services like Blob Storage, Key Vault, or Cosmos DB. It handles token acquisition only, so you still need the relevant Azure service SDK for resource operations. The package is community maintained and not affiliated with Microsoft.
- How do I install azure-oss/identity in a Laravel app?
- Install it with composer require azure-oss/identity in your Laravel project. You should also have PSR-18 and PSR-17 HTTP implementations available; Laravel applications commonly get these through Guzzle or Symfony HTTP Client. The package does not ship Laravel-specific configuration by default, so create your own config/azure.php file and bind credentials in a service provider. Store tenant ID, client ID, and secrets in environment variables or a secret manager.
- Which Azure credential flows does azure-oss/identity support?
- It supports ClientSecretCredential, ClientCertificateCredential, EnvironmentCredential, WorkloadIdentityCredential, ManagedIdentityCredential, ChainedTokenCredential, and DefaultAzureCredential. Use managed identity or workload identity for Azure-hosted workloads where possible, and client secret or certificate credentials for self-hosted services. Chained and default credentials help when the same code runs in multiple environments.
- Does azure-oss/identity work with Laravel's HTTP client and Guzzle?
- Yes. The package depends on PSR-18 and PSR-17 interfaces and uses discovered HTTP implementations when available, which fits Laravel apps that already include Guzzle or Symfony HTTP Client. You retrieve a token with the credential and then pass it to Laravel's HTTP client as a Bearer token. The identity package does not replace Laravel's HTTP client or Azure service SDKs.
- How should I store Azure credentials in Laravel?
- Keep Azure tenant ID, client ID, client secret, and certificate paths in environment variables and expose them through Laravel config files. Never hardcode secrets in source control. For production, consider Azure Key Vault or your platform's secret manager, and prefer managed identity or workload identity where it removes the need for stored client secrets. Cache configuration and restrict secret access to the application runtime.
- How do I cache Entra ID access tokens with azure-oss/identity?
- The package supports token caching through InMemoryTokenCache or a custom PSR-16 cache. In Laravel you can bind a PSR-16-compatible cache adapter and reuse tokens until they are near expiry. Caching reduces token requests, latency, and the risk of hitting Entra ID throttling limits. Make sure your cache key strategy separates tenants, clients, and scopes.
- What is the difference between DefaultAzureCredential and ChainedTokenCredential?
- DefaultAzureCredential tries a configurable chain for common Azure hosting environments; by default it includes environment and workload identity credentials, and managed identity can be enabled through DefaultAzureCredentialOptions. ChainedTokenCredential lets you define your own ordered list of credentials and stops at the first successful token. Use the default when you want broad environment compatibility, and use a custom chain when you need explicit control.
- Is azure-oss/identity production ready for Laravel applications?
- It can be used in production, but you should assess it carefully because it is community maintained, has low adoption, and provides no Laravel-specific helpers. Add robust exception handling, token refresh monitoring, and integration tests for your Azure flows. Pin the package version and review upstream changes before upgrading. For critical systems, compare it with Microsoft-supported SDKs or more established community options.
- How do I test Laravel code that uses azure-oss/identity?
- Mock the credential or identity client dependency in your Laravel container and return fake access tokens for unit tests. Keep real Azure authentication out of fast test suites and use integration tests only where you can safely supply environment credentials or managed identity. Assert that your application adds the Bearer header correctly and handles expired or failed token acquisition. Use least-privilege test identities in CI.
- What are alternatives to azure-oss/identity for Azure auth in Laravel?
- Alternatives include Microsoft Azure Identity SDKs for other languages, custom OAuth2 client credentials implementations, and other community PHP packages for Entra ID authentication. If your goal is Azure Storage, the azure-oss/storage-blob and related Flysystem packages are natural companions. Evaluate maintenance activity, PSR-18/17 support, Laravel integration effort, and production adoption before choosing.
