Computer Configuration > Policies > Centrify Settings > Mac OS X Settings > Services > Enable FTP Access
Allow users on other computers to exchange files with this computer using FTP applications.
Enabling this group policy is the same as opening the Sharing system preference, selecting File Sharing, then clicking the Options button and selecting the Share Files and Folders using FTP option.
On Mac OS X Servers enabling this policy has no effect.
This policy can take effect dynamically at the next group policy refresh interval without rebooting the computer.
