This is somewhat true. There are various server implementations but
AFAIK only one open source client. ;-)

I've tested support in web2ldap for DIT structure rules and name forms
with three different commercial servers and one open source
implementations. I still have to sort out some issues with determining
the governing structure rule at the client side (in case the DSA does
not return operational attribute 'governingStructureRule').

While this is a solution for enforcing DIT structure rules at
server-side a client cannot determine the rules and guide the user to do
the right thing.
