About Google Apps Directory Sync
Google Apps Directory Sync is a utility that adds, deletes, and moves your users
in the message security service to match the user directory on your LDAP server.
When you synchronize, any changes on your LDAP server are reflected in the
message security service.
The directory sync utility runs on a server machine in your network environment.
You can use any machine that is able to connect to your LDAP server and the
message security service.
