Some names are *really* pulled out of their ass and nowhere else...
Now, if course, that's all about certificates, which one may choose
to disconnect from the directory (or THE directory for that matter), 
but I'm of the opinion that if you store certificates in directory
entries, it's best if the entry DN matches the certificate DN...

True, we currently have a DNS structure that allows for delegation of
zone authority, and it works well.  What I'd like to know is if there
is a possibility, at least in theory, to have something similar for
directories through referals?  There would be a set of, eh, root LDAP
servers that would contain referals to countries, and the servers they
refer to would contain referals to the next level as well as entries
with only two RDNs in the name, and so on.  Basically mimicing the DNS
structure with pure LDAP.  Is this at all possible?  I've been playing
with the thought of starting something like this, if there would be an
