Verify that "/etc/sudoers" has no occurrences of "!authenticate."

Check that the "/etc/sudoers" file has no occurrences of "!authenticate" by running the following command:

$ sudo grep -i authenticate /etc/sudoers /etc/sudoers.d/*

If any occurrences of "!authenticate" return from the command, this is a finding.
