Overview of Google Apps Directory Sync 17
Users: A small number of manually added users.
In the Core IT phase, a small number of IT users activate in Google Apps and
begin learning and configuring Google Apps. The goal of the Core IT phase is to
learn how to use the applications and utilities, to configure services, and to
prepare for Early Adopters.
Directory Sync: During this phase, continue preparation and testing to be ready
for Directory Sync implementation by the Early Adopter phase.
Typically, GADS is not used to import users for the initial IT pilot, since it is easier
to add your initial IT department users either manually or by uploading a CSV file
into the Google Apps control panel.
If you do have manually added users that are not in your LDAP, remember to add
exclusion rules so those users are not deleted.
Early Adopter
Users: Early adopter business users, either manual or synchronized.
During the Early Adopter phase, set up a small number of active users and give
them the best possible user experience. Early adopters can then become familiar
with Google Apps, identify any common questions or issues, and learn to use the
product so that they can help others after a broader rollout.
Directory Sync: During the Early Adopter phase, prepare your synchronization
rules so that full synchronization will be ready on your Global Go Live date.
Optionally, you can also set up GADS to synchronize data for early adopters. You
can use any of these features for Early Adopter synchronization:
1. You can use GADS during your Early Adopters phase to synchronize your
entire user list, so that your Early Adopter users can see recipient addresses
in Autocomplete when sending mail. You can synchronize users as shared
contacts, or synchronize as full users without sending passwords or routing
users’ mail into Google Apps.
2. If you are running the Early Adopter phase on a separate test domain, GADS
can synchronize users to a test domain, adding users with the same
username in a separate test domain.
3. If you are using Postini Message Security, you can set up Postini for split
delivery, so that Early Adopters receive mail in Gmail while other users
receive mail on your legacy server.
