OwnOwner defines whether the owner SID shall be freed on destruction (true) or not (false) If the property OwnOwner is true and the property Owner is set, the old Owner TJwSecurityId instance will be freed and the new owner will be copied into a new instance. So there will be two instances of this SID and the original instance is not touched and must be freed if necessary. 

If the property OwnOwner is false, the old Owner TJwSecurityId will not be freed and the new one will directly point to the new SID. 

See Owner for information about how to use this property.
