Freenas Permissions


I was setting up some shares on a test server and was wondering if there was a way to stop the users from changing the permissions.

Setup is simple for testing purposes. 1 dataset called Company. 1 share called Public. Login to windows 7 vm and map share with testuser1 credentials, who is a member of the company group so they have r/w access(owner = root, group = company). When I right click Properties -> Security -> Edit , I am able to remove the everyone group. This is ok since i don’t want the everyone group but i would be afraid in production that a user might add it back.

Is there a way to stop testuser1 or any other users from editing permissions?
