Re: You should have been sacked
"it was most likely the same command and he just forgot to replace the default "*ALL" in one parameter, something no authorization structure can fix"
I agree about that, but for such an important command, you could at least warn. A simple "This will [insert verb, in this case reconnect] connections globally (for all users). Usually, this is not necessary. Are you sure you want to proceed?" would probably have alerted the user that they probably want to cancel the command and try again. However, as good as that solution would have been, a better one would be giving a very new employee more training than that before leaving them alone with full permissions and no backup or emergency assistance.
