Lesson 10. Replication
Because an Open Directory server provides data that is critical to the operation of your Mac OS X computers, you will need to set up more than just one server for redundancy and performance reasons. This is critical, because organizations must ensure availability in a directory-service environment. Understanding how replication works helps not only with planning and configuration, but also with troubleshooting. In a Mac OS X Server replication system, one computer called the master is duplicated onto one or more computers called replicas, letting you move directory data closer to remote sites and provide data redundancy to eliminate service disruption. This lesson outlines the replication architecture. You will learn how to set up Open Directory replica servers and how the datathe contents of the Lightweight Directory Access Protocol (LDAP) server, Password Server, and the Kerberos key distribution center (KDC)is synchronized between the master and replica servers. |
