Error on inactive user activity

[Alberto Salvante]

Hi all!

We have AD directory we are using to authenticate our users.

We have recently discovered that two of our users have the same user name in the same AD and they have different email addresses.

User A has been inactive since 2015, user B was deactivated about a month ago.
After deactivation, the activities that were done by user B are indicated as performed by user A. For example, tickets where user B was an assignee or reporter are now assigned/reporter to user A.

Any idea on the causes of this anomaly and how to fix it? 

Thank you!
Alberto

It ahs to do with the AD sync.  When you had an active account it would have been the first user with the username to sync (username is the key)  So user B would have had their name associated with all issues in Jira with that username.  When user B was deactivated it seems that user A is now syncing overriding the information in Jira.  I believe you could change the username of user A in AD and it would then sync to user B again updating all the information.  You might want to test it first if possible but I believe that is the case.
