Thanks Marc for pinpointing the documentation... RTFM ... The explaination of the difference of behavior between 11.10 and 12.04 may be explained by the differences in the original /etc/sudoers files :
Ubuntu 11.10 version : # /etc/sudoers # # This file MUST be edited with the 'visudo' command as root. # # See the man page for details on how to write a sudoers file. # Defaults env_reset # Host alias specification # User alias specification # Cmnd alias specification # User privilege specification root ALL=(ALL) ALL # Uncomment to allow members of group sudo to not need a password # (Note that later entries override this, so you might need to move # it further down) # %sudo ALL=NOPASSWD: ALL Ubuntu 12.04 : # # 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 Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin" # Host alias specification # User alias specification # Cmnd alias specification # User privilege specification root ALL=(ALL:ALL) ALL # Members of the admin group may gain root privileges %admin ALL=(ALL) ALL # Allow members of group sudo to execute any command %sudo ALL=(ALL:ALL) ALL # See sudoers(5) for more information on "#include" directives: #includedir /etc/sudoers.d There is only a README file un the /etc/sudoers.d directory. For sure, in the 12.04 version of the /etc/sudoers file these 2 new lines must have an impact on the behavior of sudo : # Members of the admin group may gain root privileges %admin ALL=(ALL) ALL # Allow members of group sudo to execute any command %sudo ALL=(ALL:ALL) ALL >From now I will carefully watch the content of the /etc/sudoers file in the >next version and updates of Ubuntu !!
