”Run As” with Azure Automation Hybrid Worker

Runbooks in Azure Automation cannot access resources in your local data center since they run in the Azure cloud. The Hybrid Runbook Worker feature of Azure Automation allows you to run runbooks on machines located in your data center in order to manage local resources. The runbooks are stored and managed in Azure Automation and then delivered to one or more on-premise machines where they are run. Source.

By default the runbook will run in the context of local system account on the Hybrid Runbook Worker. This might be a challenges, as the computer account is seldom assigned any permissions, even if possible. The scenario I was working included creation of a service account in an on-premises domain. My first idea was to change the service account for the Microsoft Monitoring Agent service. But that did not work out very well L

Next idea was to in my Azure Automation runbook do a remote session to a server with domain account as credentials. The runbook shown in this blogpost is an example of how to do a remote session within an Azure Automation runbook. The runbook use two input parameters, first name and last name. The runbook picks up the account (SKYNET Super User) that will be used to remote connect to a domain controller. The account is stored encrypted in Azure Automation as an asset. The inline script session returns the name of the new user account, which is also returned as an output (Write-output) from the runbook.

I start the runbook from the Azure Portal, input the two parameters. A short while later I can see the job is completed and the output from the runbook. I can also see the new account in Active Directory.
