I noticed that if the automatic synchronization between ocs and glpi is off these PCs are not removed.
I guess I should rivolere glpi forum, nobody here has ever had this symptom?
The elimination of the PC is always for the same devices
In practice this happens .............
The pc contact the server ocs every 24 hours, consequently:
in ocs every day I get a new ID for this pc (because the day before it was deleted);
in glpi is added as new because it does not find the matching id, obvious this creates duplicates in glpi.
For now I disabled the sync between glpi and ocs but it is not a good solution.
