Change user login with Active-Directory-Server database

[Deleted user]

Good morning,

The user management of all our software is done with our Active-Directory-Server database.

In Confluence (and many other software like Gitlab) users connect to their account with their initials but in JIRA they connect themselves with their full name (however the database is the same).

We figure out that in JIRA the User Schema Settings are not the same as in Confluence, that´s why we changed JIRA´S User Schema Settings to make it similar to Confluence. The problem is that it didn´t worked as excepted, JIRA as created new user, with new account instead of simply renaming the users.

I have found this documentation : https://confluence.atlassian.com/jirakb/ldap-username-or-samaccountname-rename-creates-a-new-user-in-jira-not-associated-with-the-previous-user-account-826875550.html

If I understand well if I put on User Unique ID Attribute field : objectGUID; I can change the User Display Name Attribute field and JIRA will not created new account and disabled the other account ?

Thank you for your answer.
