Abstract
The Lightweight Directory Access Protocol (LDAP) supports auxiliary
object classes for adding additional attributes to a directory entry.
This document defines a structural object class that may be used when
no other structural object class is available.
1. Background
Schema for LDAP directories often define auxiliary object classes
that are intended to be used with a specific structural object class.

Internet Draft namedObject schema 1 March 2001
For example, the posixGroup object class [RFC2307bis] is an auxiliary
object class that may be used to overlay POSIX group identification
on an existing group of distinguished names. In this case, it is
suggested that the groupOfUniqueNames object class be used as a
structural object class. However, this may sometimes be
inappropriate: that groupOfUniqueNames requires at least one member
may make it impossible to migrate existing group information.
[RFC2307bis] could define a specific structural object class for this
case (say, structuralPosixGroup), but this would unnecessarily add to
the proliferation of redundant schema.
This document defines a structural object class, namedObject, that
mandates no attributes other than a common name. Arbitrary auxiliary
object classes may be thus associated with entries which have this as
a structural object class.
2. Object Class Definitions
The namedObject object class defines one mandatory attribute, a
common name. The OID arc is iso(1) org(3) dod(6) internet(1)
private(4) enterprise(1) padl(5322) namedObjectSchema(13)
objectClasses(1).
( 1.3.6.1.4.1.5322.13.1.1 NAME 'namedObject' SUP top
STRUCTURAL MAY cn )
Other attributes allowed by auxiliary classes may be used for naming
purposes.
An example entry would be:
dn: cn=Sample Entry,dc=padl,dc=com
objectClass: top
objectClass: namedObject
cn: Sample Entry
An example entry with an auxiliary class from [RFC2307bis] would be:
dn: cn=wheel,ou=Groups,dc=padl,dc=com
objectClass: top
objectClass: namedObject
objectClass: posixGroup
cn: wheel
gidNumber: 0
memberUid: root
