How to enable Managed Service Accounts (MSA) Active Directory object

Check Active Directory schema version

  • Open PowerShell as Administrator
  • Run the following command
Get-ADObject (Get-ADRootDSE).schemaNamingContext -Property objectVersion

If the objectVersion value is lower than 47, which corresponds to an AD Schema version of Windows Server 2008 R2, you will need to extend the Active Directory schema to be able to use Managed Service Accounts.
