Veto :-)

The DN that comes from the server (via JNDI) is parsed to an LdapDN, we 
use the UP form when presenting the DN to the user as the user should 
see the DN with all upper and lower cased characters and spaces and so on.

In the cache of DN(String)->Entry (atm just a hashmap) we use a special 
form of a normalized DN: we replace the attribute type by its OID. That 
is necessary for the "Locate in DIT" function. Whenever you have an DN 
under your cursor you could find it in the DIT, whatever form the DN has.

We also use the DN/RDN/ATAV structures to compose an DN, e.g. when 
creating or renaming an entry.
