Change user names with LDAP authentication

[momentum]

This is currently a hypothetical question, but it seems very realistic (at least to me).

Currently there does not appear to be a way to change the username if said user uses LDAP/AD authentication.

What happens if the username in LDAP/AD is changed (marriage, divorce, legally changed name, etc)? Is there any way to update this in mindtouch so that the new username is credited with all the changes/edits/etc of the original username?

You can always go to the database, if you're the super-cautious type.

I've considered that, and have done some minor sql changes on our old deployment. However, I'm trying to keep our latest deployment "by the book". I know that mindtouch frowns heavily upon directly editing the db.
