Actually I have some Atlassian apps such as JIRA, Confluence etc. All apps were using JIRA as a user management base.
Now I've got CROWD and I've successfully moved all users from JIRA to the CROWD internal dicertory. And this is fine.
But also I have Microsoft AD, and I also have connected it as a second CROWD directory.
Now I have 2 user directoties in CROWD - internal and AD. And most of users in both directories are the same persons.
And here I've got a problem. I have a lot of issues in JIRA and pages in Confluence which were created by users from JIRA directory. And now I want to make accounts from AD and JIRA to be merged for most of the users to keep history/backlog of all the issues/pages.
So for example issue KEY-123 was created by user gogalev@me.com (from JIRA/CROWD directory). But this user has an account in my AD - Grigoriy Lev. And my goal is to let user Grigoriy Lev become a pair to user gogalev@me.com and login to JIRA/Confluence under AD account and see issue KEY-123 as my own.

Please put in on your scheduler.
