For security reasons, my customer wants to use the ‘su -‘ command.

However, when I type ‘su -‘, ‘sudo’ in ESXi, ESXi not found ‘su -‘, ‘sudo’ commands.

I found some posting that the ‘su -‘ command in the 3.x and 4.x versions of esxi, but did the command disappear from the 5.x or later version?

Additional, my customer wants to change the 3 files permission.

(/etc/shadow/  ,  /etc/cron.d/cron.allow   ,   /etc/cron.d/cron.deny)

Changing permissions is very easy, but doesn’t this affect to ESXi?
