"(all users are admin)" there is your problem.

Even if you could hide it they, being admin, could always restore the settings, see the password and hide the setting again without you even knowing. What you want (hiding something from an admin) is never going to work.

The correct solution to your problem is to make those students users and elevate privileges to what you want them to do that requires then to even need admin privileges. Like installing software, updating etc. Here is an example using policyKit: How can I set the Software Center to install software for non-root users?

  • Not going to happen. An admin in Linux can do anything. What you want are users with special privileges: the 2 basic things that require passwords are installing software and updating a system. If you let users modify /usr or /etc they -can- always reset what you did to remove the checkbox.

If founded with $ sudo gedit /usr/share/nm-applet/ce-page-wifi-security.ui and then you edit the line 55 and change True for False and in the network maneger it will appear like that. enter image description here

    Again, and I do not like repeating myself, how does that prevent any of those users to actually read this topic and go .... hey that is how I turn it back on, view the password, and set it back again?
