About Synchronization
Run the synchronization command to push your LDAP directory server user
information to Google Apps.
Before you can synchronize Google Apps with your LDAP directory server, you
must create rules that detail how to connect to both servers, and what filters and
rules to use. These rules are stored in an XML file. To create this XML file, run
Configuration Manager. For more information about Configuration Manager, see
“Configuration” on page 49.
Most administrators run their first synchronization manually to test the process,
import an initial set of users, and confirm the changes. After initial synchronization
from the Configuration Manager, you can set up automatic scheduling for future
synchronization.
Note: GADS caches Google Apps data for a maximum of eight days. If the size of
the cached data is too small to impact synchronization speed, GADS clears the
cache even more frequently to keep the data fresh.
Synchronizing from the Configuration Manager
You can perform a manual synchronization from the Sync section of the
Configuration Manager by clicking Sync & apply changes. Use this feature to
perform a new sync after setting up or modifying your configuration. After you’re
done making configuration changes, you should automate your sync process by
instead using command line synchronization.
Command Line Synchronization
GADS uses the command sync-cmd to run synchronization. This simple
command line interface gives you the flexibility to incorporate synchronization into
any scheduling or batch script you wish to use.
The command line to use for all platforms is
