The Lightweight Directory Access Protocol (LDAP) uses X.500-
compatible distinguished names  for providing unique
identification of entries.
This document defines an algorithm by which a name registered with
the Internet Domain Name Service  can be represented as an LDAP
The Domain (Nameserver) System (DNS) provides a hierarchical resource
labeling system. A name is made up of an ordered set of components,
each of which are short strings. An example domain name with two
components would be "CRITICAL-ANGLE.COM".
LDAP-based directories provide a more general hierarchical naming
framework. A primary difference in specification of distinguished
names from domain names is that each component of an distinguished
name has an explicit attribute type indication.
X.500 does not mandate any particular naming structure. It does
contain suggested naming structures which are based on geographic and
national regions, however there is not currently an established
registration infrastructure in many regions which would be able to
assign or ensure uniqueness of names.
The mechanism described in this document automatically provides an
enterprise a distinguished name for each domain name it has obtained
for use in the Internet. These distinguished names may b...
