Active Directory - username changed but only partially in JIRA

[Jacques]

Hello,

I have the following issue:

1. We sync our JIRA with our Active Directory
2. A user, with username "cmatthews" was created in Active Directory. 
3. This user created various issues in JIRA which were successfully resolved and closed.
4. This same user asks for a username change and it is changed in Active Directory to "cthomas"
5. Active Directory syncs with JIRA and successfully changes the username from "cmatthews" to "cthomas" in the [cwd_user] SQL table.
6. However, when this user now creates an issue in JIRA the associated user in the [jiraissue] SQL table remains "cmatthews".

Since we consult JIRA data throught the REST API, we cannot seem to get the issues raised by "cthomas".

I have tried to clean the JIRA cache, reindexed issues, restarted JIRA from zero, but to no success.

Our JIRA Version is: v6.3.4

Any suggestions?

thanks!
Jacques

This may be related to the following bug in JIRA:

The root of the problem is that the JIRA DB is not completely updated if a username is edited. In the GUI, worklogs are properly modified to display the new username, not so using the REST API. This means that work logs extracted using the REST API are returned with the wrong (old) username!

Good luck!
