This document summarizes the X.500 information model for collective attributes and describes use of collective attributes in LDAP (Lightweight Directory Access Protocol). This document provides schema definitions for collective attributes for use in LDAP. 1. Introduction In X.500 [X.500], a collective attribute is "a user attribute whose values are the same for each member of an entry collection" [X.501]. This document details their use in the Lightweight Directory Access Protocol (LDAP) [RFC 3377]. 1.1. Entry Collections A collection of entries is a grouping of object and alias entries based upon common properties or shared relationship between the corresponding entries which share certain attributes. An entry collection consists of all entries within scope of a collective attributes subentry [RFC 3672]. An entry can belong to several entry collections. Zeilenga Standards Track
