It is a numeric code (between 6 and 11 digits long) that allows users to authenticate themselves on the WES
(Watchdoc Embedded Solution) WES is the name given to the Watchdoc interface within the printing devices. There are interfaces that are specific to each third party device and hence as many WES versions as there are device manufacturers. These interfaces serve to manage printing from the device itself. to unlock their print jobs.
Generated from entries in the LDAP directory (see Configuring the LDAP directory), this code can be viewed by the user on the “My Account” page and by the administrator in the directory administration interface.
The PUK code can consist of between 6 and 11 digits, depending on the algorithm selected and the number of users in the directory.
You can add a prefix to it if you wish to distinguish between PUK codes from several LDAP directories that you intend to merge. This helps to eliminate any duplicates. In this case, the PUK code can be between 7 and 11 digits long.
