Introduction
Netscape Directory Server (Directory Server) is a powerful and scalable distributed
directory server based on the industry-standard Lightweight Directory Access
Protocol (LDAP). Directory Server is the cornerstone for building a centralized and
distributed data repository that can be used in your intranet, over your extranet
with your trading partners, or over the public Internet to reach your customers.
This Administrator’s Guide describes all of the administration tasks you need to
perform to maintain Directory Server.
Directory Server Overview
Directory Server provides the following key features:
• Multi-master replication—Provides a highly available directory service for
both read and write operations. Multi-master replication can be combined with
simple and cascading replication scenarios to provide a highly flexible and
scalable replication environment.
• Chaining and referrals—Increases the power of your directory by storing a
complete logical view of your directory on a single server while maintaining
data on a large number of directory servers, transparently for clients.
• Roles and Class of Service—Provides a flexible mechanism for grouping and
sharing attributes between entries in a dynamic fashion.
• Improved access control mechanism—Provides support for macros that
dramatically reduce the number of access control statements used in the
directory, and increase the scalability of access control evaluation.
• Resource-limits by bind DN—Gives you the power to control the amount of
server resources allocated to search operations based on the bind DN of the
client.
