I am testing iFolder 3.1.

I'll have 300 users. I see that a user is able to share its iFolders
with all the others users. For my project, I need to restrict this right
only to a part of the users, sometimes with 0 user, or 2 users, or 10
users, or 100...

Is it possible or not ? Perhaps with eDirectory, but I can't find how. I
would like to be sure. Then I could continue to search ;-)
