This occurs because all group memberships are copied during cloning. However, if the gMSA authorization comes through the direct computer account, you must use the Set-AdServiceAccount Windows PowerShell cmdlet together with the following argument to authorize the clone:

That cmdlet deletes Managed Service Accounts from Active Directory Domain Services and would cause an outage on the source computer. Instead, use the following cmdlet to temporarily uninstall the sMSA from the source computer:
