Abstract
This document describes the LDAP/X.500 'entryUUID' operational
attribute and associated matching rules and syntax. The attribute
holds a server-assigned Universally Unique Identifier (UUID) for the
object. Directory clients may use this attribute to distinguish
objects identified by a distinguished name or to locate an object
after renaming.

1. Background and Intended Use
In X.500 Directory Services [X.501], such as those accessible using
the Lightweight Directory Access Protocol (LDAP) [RFC4510], an object
is identified by its distinguished name (DN). However, DNs are not
stable identifiers. That is, a new object may be identified by a DN
that previously identified another (now renamed or deleted) object.
A Universally Unique Identifier (UUID) is "an identifier unique
across both space and time, with respect to the space of all UUIDs"
[RFC4122]. UUIDs are used in a wide range of systems.
This document describes the 'entryUUID' operational attribute, which
holds the UUID assigned to the object by the server. Clients may use
this attribute to distinguish objects identified by a particular
distinguished name or to locate a particular object after renaming.
This document defines the UUID syntax, the 'uuidMatch' and
'uuidOrderingMatch' matching rules, and the 'entryUUID' attribute
type.
Schema definitions are provided using LDAP description formats
[RFC4512]. Definitions provided here are formatted (line wrapped)
for readability.

RFC 4530 LDAP entryUUID June 2006
In this document, the key words "MUST", "MUST NOT", "REQUIRED",
"SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY",
and "OPTIONAL" are to be interpreted as described in BCP 14
[RFC2119].
2. UUID Schema Elements
2.1. UUID Syntax
A Universally Unique Identifier (UUID) [RFC4122] is a 16-octet (128-
bit) value that identifies an object. The ASN.1 [X.680] type UUID is
defined to represent UUIDs as follows:
UUID ::= OCTET STRING (SIZE(16))
-- constrained to an UUID [RFC4122]
In LDAP, UUID values are encoded using the [ASCII] character string
representation described in [RFC4122]. For example,
"597ae2f6-16a6-1027-98f4-d28b5365dc14".
The following is an LDAP syntax description suitable for publication
in subschema subentries.
( 1.3.6.1.1.16.1 DESC 'UUID' )
2.2. 'uuidMatch' Matching Rule
The 'uuidMatch' matching rule compares an asserted UUID with a stored
UUID for equality. Its semantics are the same as the
'octetStringMatch' [X.520][RFC4517] matching rule. The rule differs
from 'octetStringMatch' in that the assertion value is encoded using
