### Identity Limitations

BYOK authentication uses **static credentials only**. The following identity providers are NOT supported:

- ❌ **Microsoft Entra ID (Azure AD)** - No support for Entra managed identities or service principals
- ❌ **Third-party identity providers** - No OIDC, SAML, or other federated identity
- ❌ **Managed identities** - Azure Managed Identity is not supported
BYOK authentication uses **static credentials only**.

You must use an API key or static bearer token that you manage yourself.

**Why not Entra ID?** While Entra ID does issue bearer tokens, these tokens are short-lived (typically 1 hour) and require automatic refresh via the Azure Identity SDK. The `bearerToken` option only accepts a static string—there is no callback mechanism for the SDK to request fresh tokens. For long-running workloads requiring Entra authentication, you would need to implement your own token refresh logic and create new sessions with updated tokens.
