man sudoers, search for NOPASSWD.
NOPASSWD and PASSWD
By default, sudo requires that a user authenticate him or
herself before running a command. This behavior can be
modified via the NOPASSWD tag. Like a Runas_Spec, the
NOPASSWD tag sets a default for the commands that follow
it in the Cmnd_Spec_List. Conversely, the PASSWD tag can
be used to reverse things. For example:
ray rushmore = NOPASSWD: /bin/kill, /bin/ls, /usr/bin/lprm
would allow the user ray to run /bin/kill, /bin/ls, and
/usr/bin/lprm as root on the machine rushmore as root
without authenticating himself. If we only want ray to be
able to run /bin/kill without a password the entry would
be:
ray rushmore = NOPASSWD: /bin/kill, PASSWD: /bin/ls, /usr/bin/lprm
