Title:
  entry in sudoers to execute a script without password prompt as root
  has no effect since 12.04

Status in “sudo” package in Ubuntu:
  Confirmed

Bug description:
  Since many ubuntu releases I execute a script in /usr/local/bin with
  sudo without password prompt in this way:

  /etc/sudoers:
  ...

  %admin ALL = (ALL) ALL
  %admin ALL = NOPASSWD: /usr/local/bin/script

  ...

  Since Kubuntu 12.04 this entry has no effect any more. It is not
  possible to execute /usr/local/bin/script as root without password
  prompt.

  I have try this entrys too for username at maschine

  %username ALL = NOPASSWD: /usr/local/bin/script

  username ALL = NOPASSWD: /usr/local/bin/script

  %username maschine = NOPASSWD: /usr/local/bin/script

  username maschine = NOPASSWD: /usr/local/bin/script

  username ALL = (root) NOPASSWD: /usr/local/bin/script

  So I think thers is a bug, because nothing works.
