If it is a small switch or only a couple of users you are interested in then I would be tempted to use the old method of noting the existing linklight status of all the switch ports, disconnect the user and spot the difference at the switch. Plug the user back in and with luck watch the port go orange as STP runs.
If the situation is bigger, I would hire a wiring contractor to re-label the wires. They have gizmos that enable them to identify two ends of the same cable.
Once you've determined the MAC addresses that you're interested in (from the 'show cam' or 'show mac-address-table' commands) you can use the ARP table from the router on that subnet to get the corresponding IP Addresses, which may make it easier to coorelate the port on the switch to the machine.
