Managed Identity authentication

Managed Identity authentication uses managed identities in Azure Active Directory to authenticate and authorize access to Azure resources securely.

When you use managed identity authentication to connect to Microsoft Azure Synapse SQL, the user for the system assigned identity is the virtual machine for which you enable the identity. The user for the user assigned identity is the user identity that you create in the Azure portal.

Before you use managed identity authentication to connect to Microsoft Azure Synapse SQL or Microsoft Azure Data Lake Storage Gen2, be sure to complete certain prerequisites.

Create an Azure virtual machine.

Install the Secure Agent on the Azure virtual machine.

Enable system assigned identity or user assigned identity for the Azure virtual machine.

If you enable both and do not specify the client ID, the system assigned identity is used for authentication.

After you add or remove a managed identity, restart the Azure virtual machine.
