Have you considered using hooks?  I have been playing with 
_username_hook_frombackend and _username_hook_tobackend.  The former 
maps the user-provided login credentials to something horde can use 
internally, that does not change as the username does.  The latter maps 
the horde-internal id back to something meaningful to the end-user.  At 
least, this is my understanding.

My results have been very good, as far as not losing end-user data when 
the username changes.  However, there are other problems, as indicated 
in http://bugs.horde.org/ticket/?id=5844 .  If others can replicate my 
issues in different environments, maybe we can figure out what's going on.
