Renaming a DN to itself, whether or not changing case, fails.  

This should succeed, preferably for all cases, so that it is possible to change
the case of an RDN. 

This would also assist Samba4, as AD supports these renames, and I am working on
a mapping layer from OpenLDAP to Samba4. 

Howard Chu notes on the openldap-technical list that logic to allow this existed
in the past, but appears to have been lost.
