Agreed, and the proxy is a good example where flexibility is needed and 
where implementors will do what they do best: figure out a way to 
achieve their performance and scalability goals while living within the 
contraints of an IETF-defined protocol. My real point is that different 
LDAP implementators have different needs, and we need to give 
implementors sufficient flexibility to make appropriate engineering 
tradeoffs. I think draft-ietf-ldup-lcup-05 strikes a very good balance 
amoing a large set of competing needs; you and a Kurt at least disagree.
