Get Active Directory Object Owner

I’m on Core 2.0 using the Novell LDAP library (https://github.com/dsbenghe/Novell.Directory.Ldap.NETStandard), and am struggling with how to get the Owner of a computer account object in Active Directory. I can successfully grab other attributes of the object, but I can’t seem to figure out how to grab Owner (not ManagedBy, but Owner).

Can someone maybe give me a nudge in the right direction?

Thanks!
