Google Apps Directory Sync for Postini Services Administration Guide - Manual (Page 12)

Utility Overview
The directory sync utility includes several components, designed to work together.
These components are:
• Configuration Manager - Use this graphical UI to configure how the directory
sync utility will connect to the message security service and to your LDAP
server. You can also create rules for user lists, search queries, organization
mapping, aliases, distribution lists and exceptions. For more information, see
“Configuration” on page 27.
• XML Configuration File - Save configuration information from Configuration
Manager in an XML file. Use this file during synchronization.
• Synchronization Command Line - Use the command-line utility sync-cmd to
perform actual synchronization. This utility uses settings in your XML
configuration file to connect to the message security service and your LDAP
server, and updates your users and aliases in the message security service.
For more information, see “Synchronization” on page 69.
• Scheduling - Once you have used sync-cmd successfully, use your operating
system’s scheduling functionality to schedule future synchronization.
Depending on the server you use, this might be a
cron job, a Windows
Scheduled Service utility, or any other scheduling tool. For more information,
see “Synchronization” on page 69.
