Using Managed Identity for Fabric Lakehouse SQL Analytics Authentication

[Abhishek_MAQ]

Hello,

I was able to connect to the Fabric Lakehouse SQL Analytics endpoint using pyodbc along with DefaultAzureCredential for authentication in local. However, after switching to Managed Identity and deploying the solution on an Azure Container App, the authentication no longer works.

• Is Managed Identity currently supported for authenticating to Fabric Lakehouse?
• If not, what are the recommended alternatives or best practices for secure authentication in this scenario?

Appreciate any guidance on this.

Thanks!

Managed Identity is not yet supported for connecting from Azure apps (like Container Apps) to Fabric Lakehouse SQL Analytics.

✅ Use Service Principal (SPN) with Microsoft Entra ID instead:

Register an SPN in Entra ID.

Enable “Service principals can use Fabric APIs” in tenant settings.

Grant the SPN workspace + item-level access (e.g., “Read all SQL endpoint data”).

Connect with Authentication=ActiveDirectoryServicePrincipal.

👉 Managed Identity works in Data Factory/Synapse pipelines, but for app workloads, SPN is the recommended secure option.
