Sorry for "fake NethServer". Is not about the meaning of "fake". In that moment I didn't find a word for "not fully functional NethServer"! Neither now!
It's OK for me but I maintain my opinions!
The sysadmin, by definition, must do everything. It is her/his job! Why do you think that a sysadmin can damage a server only from GUI and from CLI cannot? Why somebody who is not sysadmin can reach the NS settings? The users have their own GUI, without interfere with NS settings.
