Apple Mac OS X Server (Version 10.6 Snow Leopard) - Manual (Page 119)

Chapter 6 Initial Server Setup 119
If setup data is encrypted, the server needs the correct passphrase before setting itself
up. You can use Server Assistant to supply the passphrase interactively, or you can
supply the passphrase in a file containing the passphrase in the same folder as the
corresponding auto setup profile but with a .”pass” extension.
Important: When you perform an upgrade, make sure that saved setup data won’t be
detected and used by the server you’re upgrading. If saved setup data is used, existing
server settings are overwritten by the saved settings.
Setting Up Servers Automatically Using Data Saved in a File
After you install server software, you can set up the server automatically using data
saved in a file.
To have the server configure itself without further input, place the previously
generated auto setup data file in a location where target servers can detect it.
To reuse saved setup data after reinstalling a server, store the server’s setup files on a
different local partition that isn’t erased when you reinstall the server. The setup files
are detected and reused after each reinstallation.
Important: Saved setup files cannot be applied after a server has restarted after
installation and is awaiting setup. Automatic setup data needs to be in place before a
server begins setup.
If you do not have an existing local partition where the saved setup file can be
stored during installation, you need to copy the setup file to the target server after
installation and then restart the target server. This allows the server to search for the
setup data when it starts up.
For more information on where the server looks for setup data, see “How a Server
Searches for Saved Setup Data Files” on page 118.
If you have not previously created saved setup data, see “Creating and Saving Setup
Data” on page 116.
If the setup data is encrypted, make the passphrase available to target servers.
For more information, see “Using Encryption with Setup Data Files” on page 118.
