Cannot disable password authentication for sudo

[bkrzem]

Binary package hint: sudo

Hello,

I added myself to the sudo group:
   sudo usermod -a -G sudo myusername
then used 'visudo' to modify /etc/sudoers according to the instructions in the comments
(i.e. uncommented %sudo ALL=NOPASSWD: ALL line)

then logged out and logged in again. But 'sudo' keeps asking for password.

my karmic was installed from mini.iso image.

I have the same problem. This entry:

 karlheg ALL = NOPASSWD: /etc/init.d/fetchmail

... worked fine in Maverick, but no longer functions in a fresh install of Natty. In Maverick, I could type:

 sudo -k
 sudo /etc/init.d/fetchmail awaken

... and not enter a password (or swipe my finger on the thinkfinger reader). But now, in Natty, it prompts for the password (or fingerprint) anyway. (I also tried with the fingerprint reader disabled in pam; same result.)
