Debian unlike other distros like Ubuntu does not come with sudo enabled by default. That said it is easy enough to set it up.

How to setup sudo:

1) Use visudo to edit your sudoers file
2) Add your user to the sudo group

Code:

adduser foo sudo

3) Or you can use gksu, or kdesu on KDE.

Or you can follow the simple steps here:
Debian Reference Chapter 1. - http://www.debian.org/doc/manuals/de..._configuration

HOWTO - get kdesu back to normal in KDE4 - http://forums.debian.net/viewtopic.php?f=16&t=40158
This one is actually pretty easy. In a terminal here is what you do:
Anywhere you see ## just after that is instructions you do NOT have to type the text directly AFTER the ## signs,
what you have to type will either be BEFORE the ## on a line or the line will have NO ## signs.

Code:

   ##first type in:
    su

    ##after you hit enter you will see
    Password:         ##<----------- type in your root password here.

    ##Now you will see your prompt change from a $ to a # sign

    ##Don't worry, almost done now...

    ##type:

    ln -s /usr/lib/kde4/libexec/kdesu /usr/bin/kdesu

    ##hit enter, then type:
    exit

    ##You are now back to your regular user in your terminal. Lets test that puppy out!

    kdesu dolphin

    ##The normal kdesu dialog should pop up asking for roots password with the explanation that the program 
    ##dolphin needs root permissions. You can just cancel the dialog box since it was only a test to see if the link
    ##worked.

Someone just recently pointed out that the correct way to get kdesu is to run:

Code:

dpkg-reconfigure --priority=low kdesudo

using that you choose which you want to use kdesu or kdesudo. Learn something new everyday.
