Well, with Drupal's authentication system, there's an authmap table that 
maps a user's authentication credentials to their account id (distinct 
from their username).  Additionally, it associates the authentication 
module that would use this info with it, so multiple authentication 
modules may co-exist.  That said, these credentials stay with a user 
regardless of what their username is changed to.
