+## Additional Steps with User-Assigned Managed Identity

+Repeat the steps if you selected user-assigned managed identity to connect ASA to Synapse:
+1. Create a contained database user. Replace ASA_Job_Name with User-Assigned Managed Identity. See the example below.
+   ```sql
+   CREATE USER [User-Assigned Managed Identit] FROM EXTERNAL PROVIDER;

+2. Grant permissions to the User-Assigned Managed Identity. Replace ASA_Job_Name with User-Assigned Managed Identity.

 ## Remove Managed Identity
 
 The Managed Identity created for a Stream Analytics job is deleted only when the job is deleted. There is no way to delete the Managed Identity without deleting the job. If you no longer want to use the Managed Identity, you can change the authentication method for the output. The Managed Identity will continue to exist until the job is deleted, and will be used if you decide to use Managed Identity authentication again.
