Azure Automation / runbooks - issue with SP with Thumbprint

Description of the issue

I wanted to run an export from a tenant with the help of a runbook but when i use a service principal I get the following error message:

pulling DSC from Tenant 2024-Apr-11-2004PM Exporting Microsoft 365 configuration for Workloads: AAD Finding all resources for workload {AAD} and Mode {Default} Authentication methods specified:

The code I used:

`$creds = Get-AutomationPSCredential -Name "DemoTenant" $path = "$env:TEMP" $Date = $(Get-Date -f yyyy-MMM-dd-HHMMtt)

$ApplicationId = "xxxxxx" $CertificateThumbprint = "xxxxxxx" $TenantId = 'xxxxxxxxxxx.onmicrosoft.com'

write-output "Pulling DSC from Tenant $Date"

Export-M365DSCConfiguration -Workload @("AAD") -path $path -filename "runbook_$date.ps1" *>&1 -ApplicationId $ApplicationId -CertificateThumbprint $CertificateThumbprint -TenantId $TenantId -generateinfo $true

I already installed all modules (Version 5.1) Is there an option to use runbooks and with SP with thumbprints?

@Wopienkaatwork The certificate you are using must be imported in the certificate store of the local machine, e.g. using certutil. Below you find an example how I do it on an Azure Runbook Hybrid Worker in System context.

$certPath = "C:\certificate.pfx"
$certificate = Get-PfxCertificate -FilePath $certPath
$thumbPrint = $certificate.Thumbprint
$null = "" | certutil -f -importpfx $certPath NoRoot

Export-M365DSCConfiguration...

The certutil command imports the pfx without the Root certificate in its chain and overwrites any previously existing certificate with that name. You could do this with Import-PfxCertificate as well, but in my case that didn't quite work out. But that's another story.
