Eu uso o Ubuntu 14.04 e tentei mudar o tempo limite da senha sudo, mas a mudança feita para ele não funciona. Por favor ajude, Meu arquivo visudo se parece com isso.
GNU nano 2.2.6 File: /etc/sudoers.tmp
#
# This file MUST be edited with the 'visudo' command as root.
#
# Please consider adding local content in /etc/sudoers.d/ instead of
# directly modifying this file.
#
# See the man page for details on how to write a sudoers file.

Defaults env_reset,timestamp_timeout=15
Defaults mail_badpass
