Specify how to authorize operations on a specific file share

You can change the authentication method for individual file shares. By default, the portal uses the current authentication method. To determine the current authentication method, follow these steps.

  1. Navigate to your storage account in the Azure portal and select Data storage > File shares from the left navigation.

  2. Select a file share.

  3. Select Browse.

  4. The Authentication method indicates whether you're currently using the storage account access key or your Microsoft Entra account to authenticate and authorize file share operations. If you're currently authenticating using the storage account access key, you'll see Access Key specified as the authentication method, as in the following image. If you're authenticating using your Microsoft Entra account, you'll see Microsoft Entra user account specified instead.

Authenticate with your Microsoft Entra account

To switch to using your Microsoft Entra account, select the link highlighted in the image that says Switch to Microsoft Entra user account. If you have the appropriate permissions via the Azure roles that are assigned to you, you'll be able to proceed. However, if you lack the necessary permissions, you'll see an error message that you don't have permissions to list the data using your user account with Microsoft Entra ID.

Two additional RBAC permissions are required to use your Microsoft Entra account:

  • Microsoft.Storage/storageAccounts/fileServices/readFileBackupSemantics/action
  • Microsoft.Storage/storageAccounts/fileServices/writeFileBackupSemantics/action

Authenticate with the storage account access key

To switch to using the account access key, select Switch to access key. If you have access to the storage account key, then you'll be able to proceed. However, if you lack access to the account key, you'll see an error message that you don't have permissions to use the access key to list data.

Azure built-in roles for tables

Azure RBAC provides built-in roles for authorizing access to table data using Microsoft Entra ID and OAuth. Built-in roles that provide permissions to tables in Azure Storage include: Storage Table Data Contributor: Use to grant read/write/delete permissions to Table storage resources. Storage Table Data Reader: Use to grant read-only permissions to Table storage resources. To learn how to assign an Azure built-in role to a security principal, see Assign an Azure role for access to table data. To learn how to list Azure RBAC roles and their permissions, see List Azure role definitions. For more information about how built-in roles are defined for Azure Storage, see Understand role definitions. For information about creating Azure custom roles, see Azure custom roles. Only roles explicitly defined for data access permit a security principal to access table data. Built-in roles such as Owner, Contributor, and Storage Account Contributor permit a security principal to manage a storage acc...

Explore Dataflows Gen2 in Microsoft Fabric

  In Microsoft Fabric, you can create a Dataflow Gen2 in the Data Factory workload or Power BI workspace, or directly in the lakehouse. Since our scenario is focused on data ingestion, let's look at the  Data Factory  workload experience. Dataflows Gen2 use Power Query Online to visualize transformations.  1. Power Query ribbon Dataflows Gen2 support a wide variety of data source connectors. Common sources include cloud and on-premises relational databases, Excel or flat files, SharePoint, SalesForce, Spark, and Fabric lakehouses. Then there are numerous data transformations possible, such as: Filter and Sort rows Pivot and Unpivot Merge and Append queries Split and Conditional split Replace values and Remove duplicates Add, Rename, Reorder, or Delete columns Rank and Percentage calculator Choose Top N and Bottom N You can also create and manage data source connections, manage parameters, and configure the default data destination in this ribbon. 2. Queries pane The ...

Select and configure an appropriate method for access to Azure Blobs

Azure Storage supports using Microsoft Entra ID to authorize requests to blob data. With Microsoft Entra ID, you can use Azure role-based access control (Azure RBAC) to grant permissions to a security principal, which may be a user, group, or application service principal. The security principal is authenticated by Microsoft Entra ID to return an OAuth 2.0 token. The token can then be used to authorize a request against the Blob service. Authorization with Microsoft Entra ID is available for all general-purpose and Blob storage accounts in all public regions and national clouds. Only storage accounts created with the Azure Resource Manager deployment model support Microsoft Entra authorization. For optimal security, Microsoft recommends using Microsoft Entra ID with managed identities to authorize requests against blob, queue, and table data, whenever possible. Authorization with Microsoft Entra ID and managed identities provides superior security and ease of use over Shared Key author...
