Active Directory Fields Synchronization
I appreciate it very much if there are more users fields of options to synchronize with the existing information in Active Directory in "Setup->Authentication->LDAP Directorys->MY AD CONFIGURATION>Users", combined with Administrations-> Users.
For example:
In "Administrations->Users->MY USER FROM AD->User", there is the "LOCATION" field, but in "Setup->Authentication->LDAP Directorys->MY AD CONFIGURATION->Users", there is no field with this option so I can sync from AD this information.
Thus, other options that would be important to sync with AD:
Name in AD | LDAP Name |
Description | description |
Office | physicalDeliveryOfficeName |
Street | streetAddress |
City | l |
State/Province | st |
Country | co |
Department | department |
Company | company |
Manager | manager |

E-Signature with pki.js and mozilla pdf.js
PKI.js
PKIjs is a pure JavaScript library implementing the formats that are used in PKI applications (signing, encryption, certificate requests, OCSP and TSP requests/responses). It is built on WebCrypto (Web Cryptography API) and requires no plug-ins.
Some examples:
Signature verification and PDF sign example:
https://pkijs.org/examples/PDFexample.html
https://mozilla.github.io/pdf.js/
PDF.js
A general-purpose, web standards-based platform for parsing and rendering PDFs.
https://github.com/mozilla/pdf.js/issues/4743
We have implemented both signing and signature verification of PDFs in browser using https://pkijs, you can see an early signature verification demo here: https://pkijs.org/examples/PDFexample.html we have not yet integrated with PDFjs but will be doing that in the not so distant future. Our intention is to release most of this as OSS and give back any changes to PDFjs that are necessary to make integration smooth.

Private Documents
Can you please make a feature to allow documents to be made private in a ticket.
Every now and again we need to attach a documents to a ticket that contains private information.
As documents are not private we have been saving these documents into our departments shared network drive.
Not saving these documents to the ticket often causes issues if the case is reviewed at a later date.

Multiple conversations in a ticket
Let's say someone creates a ticket in our system. We may need to be contact 3th parties for the ticket. We perhaps would contact someone else (his boss, a supplier) through mail. In GLPI you have to do that through other means, and log the result in GLPI once done.
The problem with this is that it's much harder to have teams working on a ticket, as some info is handled outside the ticket.
GLPI could allow the agent to pick a user to send a mail to. (This mail could be marked as private even by adding something to the mail, that way a reply would be private too).
This is something that is handled for example in OTRS in a very good way.

Easy checkout/checkin for loaner asset
While you can use the GLPI reservations interface for immediate checkout/checkin of reservable assets, it is a bit cumbersome. I wrote a proposal, publicly available from my google disk (click link), for a simplified check-out/check-in solution. (I found it a bit lengthy to post in full here, and can't see any option to attach a file.)
An implementation of this functionality would simplify handling of loaner assets "over the counter", and also facilitates self service stations for registering loan/return.
