The dus_id (under Linux) is supposed to be a unique field. Unfortunaetly Unfortunately when a Linux machine is cloned under VMware (and likely other hypervisors) this unique id is not recreated. System Administrators should do this, but it appears not many do and we end up with false positive matches occurring. This was not an option prios prior to 1.14.2, but now is.
VMware (at least on the desktop) can also provide issue's for us with Mac Addresses. If mutiple multiple desktops have VMware Workstation (or Fusion) installed, VMware tends to use the same bunch of Mac Addresses across machines. In theoy theory this should be fine (for VMware) because these machines are on different networks. Obviously for Open-AudIT this presents an issue when we match machines based on Mac Address. hence the option for match_mac_vmware. Leave this at 'n' to prevent this occurring.
