Hi ShamenParis,

Confirming the details from my end.

1. Given reader role to the account signing into Databricks. This user adrinilmitraazure_gmail.com#EXT#@adrinilmitraazuregmail.onmicrosoft.com has Reader role in storage account IAM alongside Access Connector has Storage Blob Data Contributor Role.

2. My ADLS Gen2 Path is: abfss://unitycatalogcont@stgaccuntitycatalog.dfs.core.windows.net/metadirectoryadri

and Access Connector ID is copied from Access Connector Resource ID:  /subscriptions/3d41ae7a-6c82-440f-8ec8-d1df27199109/resourceGroups/resourcesuntitycatalog/providers/Microsoft.Databricks/accessConnectors/AccessConnectorUnityCatalog

3. Step 1: Check the Tenant ID of the Access Connector Subscription- Checked subscription(hosting the Access Connector) ID: 3d41ae7a-6c82-440f-8ec8-d1df27199109 has parent management group as b2a24d99-4b47-403d-8bc4-359568eed7b7.

Step 2: Check the Tenant ID of your Databricks Account

I can confirm that the related workspace in databricks is using the same subscription 3d41ae7a-6c82-440f-8ec8-d1df27199109 where the Tenant ID is same b2a24d99-4b47-403d-8bc4-359568eed7b7.

But still getting the same issue:

Azure Managed Identity Credential with Access Connector Id /subscriptions/3d41ae7a-6c82-440f-8ec8-d1df27199109/resourceGroups/resourcesuntitycatalog/providers/Microsoft.Databricks/accessConnectors/AccessConnectorUnityCatalog and Managed Identity ID: for Account Id: 5d77c2be-ed5c-45c8-b5ee-44e20f21d1f9 could not be found.

Please let me know what to do now?
