Chapter 1. Introduction to Red Hat Admin Server

Identity management and directory services with Red Hat Directory Server use three components,

working in tandem:

A Java-based management console

An administration server which also functions as a web server

An LDAP directory server

Figure 1.1. Int eractions between t he Console, Admin Server and Direct ory Server

The Admin Server processes configuration requests for Directory Server instances and performs many

common server tasks, such as stopping and starting server instances. Directory services are usually

divided into two categories: configuration databases which store the Console and Admin Server settings

and some Directory Server configuration and user databases which contain user and group information.

These databases can be kept in the same Directory Server instance, but it is also possible to break

these services into separate Directory Server instances. In that case, a Directory Server instance's

configuration are stored in a separate Directory Server, called the Configuration Directory Server, and

user data is stored in the User Directory Server. Because the Admin Server processes server

configuration requests for Red Hat Directory Server, the Configuration Directory Server and User

Directory Server instances are both defined in the Admin Server configuration.

As a web server, the Admin Server provides all of the online functions of the Directory Server, including

handling connections to the Console and hosting web applications such as Admin Express. Clients

connect to the Admin Server both over secure and standard connections, since the Admin Server

supports both HTT P or HT T PS, if SSL/T LS is enabled.
