FWIW, I suspect this is his issue.  I use both DBD::Pg and Net::LDAP 
extensively and I have very good metrics from both of them.  But in a tree of 
20,000 objects, he should easily be able to pull 15k queries/sec on decent 
hardware out of OpenLDAP and I suspect PostgreSQL (or any other RDBMS) 
couldn't come close.
