!!! Overview
[{$pagename}] is defined in [RFC 4514]

In [X.500]-based [directory systems|Directory Service] [X.500], including those accessed  using the [Lightweight Directory Access Protocol] ([LDAP]) [RFC 4510],  [Distinguished Names] ([DNs]) are used to unambiguously refer to directory entries [X.501][RFC 4512].

The structure of a [DN] [X.501] is described in terms of [ASN.1] [X.680]. In the [X.500] [Directory Access Protocol] [X.511] (and other [ITU]-defined directory protocols), DNs are encoded using the [Basic Encoding Rules] ([BER]) [X.690].  In [LDAP], [DNs] are represented in the string form described in [RFC 4514].

It is important to have a common format to be able to unambiguously represent a [Distinguished Name].  The primary goal of [RFC 4514] is ease of [encoding] and [decoding].  A secondary goal is to have names that are human readable.  It is not expected that [LDAP] implementations with a human user interface would display these strings directly to the user, but that they would most likely be  performing translations (such as expressing attribute type names in the local national language).

Comparison of Distinguished Names] for equality is to be performed in accordance with the [distinguishedNameMatch] matching rule [RFC 4517].!! More Information
