In X.500-based directory systems [X.500], including those accessed In X.500-based directory systems [X.500], including those accessed
using the Lightweight Directory Access Protocol (LDAP) [Roadmap], using the Lightweight Directory Access Protocol (LDAP) [Roadmap],
distinguished names (DNs) are used to unambiguously refer to directory distinguished names (DNs) are used to unambiguously refer to directory
entries [X.501][Models]. entries [X.501][Models].
The structure of a DN [X.501] is described in terms of ASN.1 [X.680]. 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 In the X.500 Directory Access Protocol [X.511] (and other ITU-defined
directory protocols), DNs are encoded using the Basic Encoding Rules directory protocols), DNs are encoded using the Basic Encoding Rules
(BER) [X.690]. In LDAP, DNs are represented in string form. (BER) [X.690]. In LDAP, DNs are represented in the string form
described in this document.
It is important to have a common format to be able to unambiguously It is important to have a common format to be able to unambiguously
represent a distinguished name. The primary goal of this represent a distinguished name. The primary goal of this
specification is ease of encoding and decoding. A secondary goal is specification is ease of encoding and decoding. A secondary goal is
to have names that are human readable. It is not expected that LDAP to have names that are human readable. It is not expected that LDAP
implementations with a human user interface would display these implementations with a human user interface would display these
strings directly to the user, but would most likely be performing strings directly to the user, but would most likely be performing
translations (such as expressing attribute type names in the local translations (such as expressing attribute type names in the local
national language). national language).
