It's by design. There's a timeout that you can set, try man sudo.

Although sudo starts asking for password after the time stamp expiry.

in other words:

% sudo mkdir /newdir
<sudo asks for password authentication, creates the directory after
successful authentication>

% sudo -k

% sudo -K

% sudo mkdir /another_new_dir
<sudo don't ask for password authentication, and creates the directory>

In sudoers file, NOPASSWD is NOT set.
here is my sudeors file:

Output of "uname -a":

Is this known bug? If not, then it might have security implications.
