Unable to Enable Unity Catalog – Azure Managed Identity Credential Not Found

Shubh5073 — Tue, 11 Aug 2026 12:37:44 GMT

Hi Databricks Community,

I am trying to enable Unity Catalog in my Azure Databricks account. As part of the setup, I created an Azure Databricks Access Connector and assigned its managed identity the required permissions on my ADLS Gen2 storage account.

I then provided the Access Connector Resource ID and ADLS path in the Databricks Account Console. However, I am getting the following error:

Azure Managed Identity Credential with Access Connector Id /subscriptions/7c585268-20a0-4c57-b952-bf6a47dd315a/resourceGroups/shubh_rg/providers/Microsoft.Databricks/accessConnectors/shubh_connect and Managed Identity ID: for Account Id: 1b687630-77a8-4ff1-888e-a2837de30bf8 could not be found.

Configuration

Azure Subscription ID: 7c585268-20a0-4c57-b952-bf6a47dd315a
Resource Group: shubh_rg
Access Connector: shubh_connect
Access Connector Resource ID: /subscriptions/7c585268-20a0-4c57-b952-bf6a47dd315a/resourceGroups/shubh_rg/providers/Microsoft.Databricks/accessConnectors/shubh_connect
Databricks Account ID: 1b687630-77a8-4ff1-888e-a2837de30bf8
Storage: Azure Data Lake Storage Gen2
Managed Identity: System-assigned managed identity
ADLS Role: Storage Blob Data Contributor

The Access Connector has been successfully created in Azure, and the managed identity has been assigned the required permissions on the ADLS storage account.

However, the Databricks Account Console is unable to find or validate the Access Connector.

Questions

Why is the Databricks Account Console unable to find the Access Connector?
Is there any account-level configuration or prerequisite required before creating the Unity Catalog metastore?
Does the Access Connector need to be associated with the Databricks workspace/account in any additional way?
Is there any issue with the managed identity configuration or Access Connector Resource ID?

Any guidance on how to resolve this issue would be greatly appreciated.

Thank you.

Hi @Shubh5073 ,

As per my understanding of the issue you are facing, the error indicates that Databricks cannot locate the Access Connector resource in Azure, rather than a problem with your ADLS permissions (since you already correctly assigned Storage Blob Data Contributor).

The most common cause for this specific "could not be found" error is missing Azure permissions. The identity you are using to log into the Databricks Account Console must have the Reader role on the Access Connector resource in Azure, otherwise Databricks cannot verify its existence (I would say check your access on the Access Connector). Additionally, ensure the Resource ID is copied exactly from the Azure Portal's JSON view, as it is strictly case-sensitive.

To address your configuration question: If you are setting up the root storage for a completely new Metastore, this must be done at the Account level. However, if you are simply creating an External Location for an existing Metastore, you can create the Storage Credential directly within the Workspace UI. You only need the appropriate metastore admin privileges to create the credential, which you can then use to configure your external locations.
