CAS 3 support and automatic e-mail extraction
I'm not an expert php developer but I managed to add support for CAS 3 in glpi in order to access the CAS user e-mail address if available. The idea being that when a user logs in for the first time through CAS, the e-mail adress is automatically retrieved. But I don't know if it breaks compatibility with CAS 2 previously used
I can try to create a PR for this but I'm not sure about the testing part.
I can also provide the diff if that can help, there are not many lines of code

drop-down lists
In the company in which I work we are using glpi about a year ago, it is version 9.1.2, it would really be very useful if you glpi in the inventory menus or others display dependent lists, to put a concrete example, suppose there is a phone category in type, in turn this hierarchically should correspond to certain manufacturers and this should reduce the list to choose the model concatenating the above conditions. This would substantially reduce the amount of redundancy in the database and the manual errors that are made when selecting the equipment.
If this idea is already in a thread please let me know to give my support and unify around a single discussion
thank you and I hope this serves somehow

Enable Child entities for software by default
Any way to set "child entities" to yes by default (for new created software?). When fusion inventory creates new software, I've had them separately for each entity.

Showing device sub-type on used and managed items
Any front-end way to do this?
Reason: Many plugins (fusion inventory, flyve ...) determine (smart)phones as computers.
It would be much easier to see at the first page, if this device is a computer/notebook or a computer/desktop or a computer/smartphone

Mise à jour GLPI 0.83.4 vers GLPI 9.2.1
Bonjour! Tout d’abord je remercies le(s) administrateur(s) de ce forum pour cet espace de partage que vous nous offrez. Pour en venir au faits, je suis dans l'urgence de mettre à jour le site sur le quel je suis chargé de GLPI, étant sur la version 0.83.4 je voudrait passer à la 9.2.1. J'ai :
réinstalle la dernière version de Xampp
-renommé l'ancien dossier GLPI
-de-zippé le nouveau GLPI dans le répertoire C:\xampp\htdocs
-la connexion avec mon ancienne base de donnée glpi est réussite mais lors de la mise à jour, le passage à la version 84.0 , un message d'erreur s'affiche me disant
"
0.84 clean logs for reminder_kb - Erreur durant l'éxecution de la requête :
DELETE FROM `glpi_logs` WHERE `itemtype` IN ('Entity', 'User', 'Profile',
'Group') AND `itemtype_link` IN ('Reminder', 'Knowbase') - L'erreur est Table
'glpi 2016.glpi_logs' doesn't exist"
Merci pour vos approches de solutions.

Alert before certificate expires
on version 9.2.1 the certificate have only one alert called "Alarms on expired certificates" which is good as it indicates you have not replaced the certificate in time.
We would need, like the old certificate plugin, an alert that begin to alert a group the certificate will expires in X days and based on certificate status information
