I'm having some problem removing Netware 5 license objects from a now-unused OU. The server was removed successfully (no errors) and all other subordinate objects. But I cannot delete the license (serial number) objects. I get error -672, indicating I (logged in as admin) don't have sufficient rights. The person who installed the license objects is long gone, so what are my options?

I tried dstrace -a but I don't see the license objects. Also tried C1 and NWAdmin.
