We currently use Active Directory for user logins to Jenkins. However, our repositories are not connected to AD, and so users have a different username for them.
For example a user A might have username userA in AD, while have Auser in subversion, and user1 in CVS.

Would it be possible to allow the admin to set additional usernames for a single person? This would help eliminate multiple entries for the same person in the "People" list, and also let Jenkins realise that Auser and user1 (and userA) are the same person?
