Currently, we don't have a specific group policy to configure the master password for Mac OS X. However, you can achieve this by using the "Copy File" Group Policy.

1) Login to the Mac with local administrator account and configure the master password as desired.

2) Copy the following files to SYSVOL on the domain controller.

     The location of SYSVOL is assumed to be: \\DomainController\SYSVOL\DomainName

• /Library/Keychains/FileVaultMaster.cer
• /Library/Keychains/FileVaultMaster.keychain

    You can either drop the files here or create a folder to do so.

    In this example, a folder "Files" is created to put the files underneath it.

3) Open Group Policy Object Editor and select the group policy object that you want

4) Select Computer Configuration > Centrify Settings > Common Unix Settings.

     Then, double-click "Copy files" group policy and enter information as shown below.
