Groups to use with ACLs?

I'd like to hide certain objects from non-admin users. I can chmod +a "everyone deny read" /path/to/item and that certainly hides it from everyone! Now I'm trying to find a group that consists of any/all users with admin privileges. Neither wheel nor staff do the trick. The chmod man page doesn't help, as the examples it provides are just that... examples. I don't see any of my users in /etc/passwd or their usernames mentioned in /etc/group so I'm a little lost :-(

Are you trying to hide local stuff or folders on the server?

Local stuff.

Anyone?

I want to keep regular users from seeing the Security & Privacy pane, but allow administrators to access it. I tried:

chmod +a "everyone deny list" /System/Library/PreferencesPane/Security.prefPane
chmod +a "admin allow list" /System/Library/PreferencesPane/Security.prefPane

But that doesn't work.

chmod +a "everyone deny list" /System/Library/PreferencesPane/Security.prefPane
chmod +a# 0 "admin allow list" /System/Library/PreferencesPane/Security.prefPane

seems to have done the trick.
