Abstract

A directory can be centralized or distributed.If a directory is centralized, there is one directory server (or a server cluster) at one location that provides access to the directory.If the directory is distributed, there is more than one directory server, usually geographically dispersed, that provides access to the directory.When a directory is distributed, the information stored in the directory can be partitioned or replicated.When information is partitioned, each directory server stores a unique and non-overlapping subset of the information.That is, one and only one directory server stores each directory entry.The technique to partition the directory is to use LDAP referrals.LDAP referrals
