Azure Storage table with AD identity and Powershell

Teddy Dubois 161 Reputation points

Hello all,

I can't find what is missing in my code/setup to retrieve data from a Storage Account Table using Powershell and Azure AD Service Principals.

I have a Storage Account I will name mystorageaccount
In that Storage Account, a Table named MyTable1
I have a Service Principal that I use in my automation to access the Azure environment. It has Contributor RBAC on the Management Group level and Storage Table Data Reader RBAC on the Storage Account.
Reading and changing configuration in Azure works fine with that Service Principal, so the authentication works. However, when trying to read data from the Azure Table, it sees the table but, not the data in it.

No error, just an empty response when using "Get-AzTableRow".
If I use the Access Key of the Storage Account, Get-AzTableRow retrieves the data successfully.

$psCred = New-Object System.Management.Automation.PSCredential($applicationId, $applicationSecret)  
$context = Connect-AzAccount -ServicePrincipal -Credential $psCred -Tenant $tenantId  
$ctx = New-AzStorageContext -UseConnectedAccount -TableEndpoint  ""  
$storageTable = Get-AzStorageTable -Context $ctx –Name "MyTable1"   
$Cloudtable = $storageTable.CloudTable  
$data = Get-AzTableRow -table $storageTable.CloudTable  

How can I get the data from my Table with a Service Principal if this code above is not correct?

Thank you in advance,

    @Teddy Dubois Please refer to this document that talks about the acceptable authorization for Azure Table-

    "The AzTable PowerShell module supports authorization with the account access key via Shared Key authorization. The examples in this article show how to authorize table data operations via Shared Key.

    Azure Table Storage supports authorization with Azure AD. However, the AzTable PowerShell module does not natively support authorization with Azure AD. Using Azure AD with the AzTable module requires that you call methods in the .NET client library from PowerShell."

    Hope this helps.
