Computer Configuration > Policies > Centrify Settings > Mac OS X Settings > Services > Enable Personal Web Sharing
Allow users on other computers to view Web pages in each user’s
sites folder on the local computer.
Enabling this group policy is the same as opening the Sharing system preference and selecting the Web Sharing 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.
