...and the reason to prefer a globally unique namespace is that it may
avoid future grief in your use of LDAP. E.g. LDAP server can cooperate.
Set up referrals to each other so if you search in a DN "outside" your
own server, the client gets a referral to a server which might hold that
DN. Or they can replicate part of each others' contents. Or you might
move your LDAP data to someone hosting LDAP for you, along with data for

...note that the "dc" attribute name is short for "domainComponent",
while "o" is short for "organizationName". See the core LDAP schema
in RFC 4519. Not that LDAP knows or cares, only its users do.
