Google Apps Directory Sync Administration Guide - Manual (Page 20)

20 Release 4.0.2
Server Requirements
• A server to run GADS. The server should run one of the following operating
systems:
• Microsoft Windows (supported on XP, Windows 7, Windows 8, Windows
Server 2003/2008/2012)
• Linux
• If you’re using a 32-bit version of GADS on a 64-bit Linux system, a 32-bit
libc (such as libc6-i386 ) must be installed.
• At least 5 GB of disk space for log files and data. If you are running with
DEBUG or INFO level of logging, you may need more free space than this for
additional log data.
• At least 256 MB of free RAM. At least 1 GB of free RAM is recommended if
you have less than 10,000 users, or 2 GB of free RAM if you have more than
10,000 users. For very large organizations (over 250,000), further tuning may
be needed.
• An LDAP server with user information which is accessible to GADS. All
versions of the LDAP protocol are supported.
• Network access to your LDAP server. You do not need to run GADS on your
LDAP server.
• Read and execute administrative access over the appropriate OU structure of
the LDAP server.
• An LDAP browser that can read and browse your LDAP directory server data.
• Network access to the Google Apps through HTTPS, directly or through a
proxy server. This includes ports 80 and 443.
• For best results, a network connection to Google Apps with no proxies or
firewalls is recommended.
• A mail server able to accept and relay notifications from Directory Sync.
• Access to SSL Authorities for your network.
Level of Effort and Expertise
The level of effort for using GADS varies based on the scope of your
synchronization plans, your familiarity with the LDAP query language, and your
familiarity with your own LDAP directory server and data.
In many cases, the initial configuration of GADS includes multiple revisions of
synchronization rules, updating and refining your LDAP synchronization rules until
a simulated sync delivers expected results.
