After you have associated the MAC address of a dock to a switch port, it displays with both the current user and an Unknown User. Then you find that you cannot remove the Unknown Person from the wire-up desk mapping, or remove a previous desk’s mapping.
Resolution
Do not remove the Unknown Person from the Wire-up Module.
Reason 1 - LDM not running
Find out if the user's LDM is running, refer to LDM Maintenance.
Reason 2 - Serraview cannot match the user
The person’s details are not part of the Serraview people data. If Serraview does not have the details of a person, we cannot display them in Locator.
Locator identifies people by comparing their user name to the value of their user name in the People details. If there is not an exact match, we cannot accurately display a person in Locator.
It could display two users because there are two different switch ports associated with the desk. You can re-wire a desk, see below, Re-wire a desk for a switch port assigned to the wrong desk.
