The DN should not be relevant to end-users. Applications using simple binds 
should be configurable on which attribute to search on to identify the DN with 
which to bind. DN construction, or other methods should be avoided.

An entry has one DN.

You may be able to rewrite DNs from one form to another, but then why not just 
configure your applications correctly?

Why is the DN form so important to you?
