I did not notice it but it has been quite a while since I entered the password for using sudo priviledges.

Here is my /etc/sudoers file:

#
# 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    mail_badpass
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
%jupiter ALL=NOPASSWD: /usr/lib/jupiter/scripts/bluetooth, /usr/lib/jupiter/scripts/camera, /usr/lib/jupiter/scripts/cpu-control, /usr/lib/jupiter/scripts/resolutions, /usr/lib/jupiter/scripts/rotate, /usr/lib/jupiter/scripts/touchpad, /usr/lib/jupiter/scripts/vga-out, /usr/lib/jupiter/scripts/wifi

This worries me because any script can now run without me having to enter the password.

I have seen the following questions, but they seem unrelated to this post:

How do I make sudo always prompt me for a password(expept for the timeout duration given in /etc/sudoers file?

P.S.: I have some aliases set in my .bash_aliases that have commands using sudo, but I hope that is unrelated to the password prompt, or is it?

Your last line is the culprit. I do not know why, maybe it's a bug or I do not know all Linux rules.

You should consider these lines:

# Please consider adding local content in /etc/sudoers.d/ instead of
# directly modifying this file.

So remove the last line and put it in /etc/sudoers.d/sudo-jupiter. Now revert back permissions on /etc/sudoers to u-x and restart the system.

I found that installing grizzly openstack using devstack using the on Ubuntu 12.10 created a file /etc/sudoers.d/50_stack_sh whose contents are as follows:

jobin ALL=(root) NOPASSWD:ALL
Defaults:jobin secure_path=/sbin:/usr/sbin:/usr/bin:/bin:/usr/local/sbin:/usr/local/bin

This removed the prompt for password for all commands and I could run these commands as root and thus I was never prompted for a password.

To solve this, I deleted the /etc/sudoers.d/50_stack_sh file(I did not need openstack anymore). For those who need openstack and a password prompt too, change the contents of the file /etc/sudoers.d/50_stack_sh to:

<username> ALL=(root) ALL
Defaults:<username> secure_path=/sbin:/usr/sbin:/usr/bin:/bin:/usr/local/sbin:/usr/local/bin

Replacing <username> by the username of the account where password prompt is needed.

This answer was based on user neckTwi's answer and a question on Unix and Linux regarding the syntax of /etc/sudoers file.

N.B.: I have raised a question on ask.openstack.org asking for clarification about the method mentioned above, hope we get an answer soon :)
