The individual hosts authenticate themselves against the registration server (NCC or SMT) amongst other with a 32-digit hexadecimal unique ID and a similar password. This credential set gets automatically created by the update stack on each machine during the initial registration. When a given client re-registers with NCC/SMT, the unique ID is used for identification. Re-registration by default happens regularly on SLE 10 machines, while it must be user-initiated for SLE 11 and newer. These registrations (by unique ID) also used to count the license usage in the NCC.
Due to the dependency on maintaining true unique IDs for each individual SLE instance, it is crucial to ensure correct handling of this as part of the cloning of either physical or virtual SLE 10 and/or 11 hosts.
Currently there is no way to safely detect if a machine/unique ID has been cloned. Even though the MAC address may have changed, that could also have changed for simple reasons like replacement/addition of a network card.
SLE 11 hosts :
Delete the file
The first time the registration is run on a clone, the update stack will regenerate the file with new content.
SLE 10 hosts :
Delete the files
The zmd daemon will recreate the files with a new credential set.
