The major components of Directory Server include:
An LDAP server - The core of the directory service, provided by the ns-slapd daemon, and compliant with the LDAP v3 Internet standards.
Directory Server Console - An improved management console that dramatically reduces the effort of setting up and maintaining your directory service. The directory console is part of Red Hat Console, the common management framework for LDAP directory services.
SNMP Agent - Permits you to monitor your directory server in real time using the Simple Network Management Protocol (SNMP).
Online backup and restore - Allows you to create backups and restore from backups while the server is running.
