I'll have to look at how OpenLDAP does this.  It may 
be that you are correct.  However, support for transactions
and rollbacks may save us.

The domain+user makes a unique identifier anyways so this
adds overhead which is not necessary.

I think a cleaner solution maybe to simply verify that 
no extra indexes are leftover before adding the record.
I'm going to wave off this thread until I know more about
