Thanks for confirming the current state.

I'm working on a proposal in the IETF that uses LDAP to store file 
system namespace information:

 http://www.ietf.org/internet-drafts/draft-ietf-nfsv4-federated-fs-protocol-01.txt

Our schema is sprinkled throughout Section 6. In Section 6.3 we define 
two LDAP objects, the FSN and FSL (the exact schema definitions in the 
current draft have some typos that will be cleaned up in the next 
version).

An FSN is intended to be superior to its FSLs in a DIT. I was 
considering including DIT Structure Rules in the draft as a way to 
enforce this arrangement. However, I'm not inclined to do this if 
popular LDAP implementations, such as OpenLDAP, don't support them.

If there is a standard, well supported mechanisms for enforcing DIT 
structure, I'd be interested to know about it.
