Hi,

Interesting. I hadn't heard of this before, but from some quick Googlings it seems that this is the default behaviour of sudo on openSUSE. If you edit the sudoers file you'll probably find a line like this:

Defaults targetpw

If you comment that line out, then sudo should prompt for the user's own password rather than the password for the root account.

On to your second point, specifying commands a user or group can run. That can be done with an entry like this (in this case, I'm specifying the commands that members of the unixforum group can run without being prompted for a password):

%unixforum ALL=NOPASSWD: /bin/ls,/bin/mkdir,/bin/rmdir

Here's an example session with that entry in place (and still with Defaults targetpw set to give a clear contrast):

Code:
$ id
uid=1002(unixforum) gid=1002(unixforum) groups=1002(unixforum)
$ sudo /bin/ls /root
Desktop  mbox  Pictures
$ sudo /bin/mkdir /root/testdir
$ sudo /bin/ls -ld /root/testdir
drwxr-xr-x 2 root root 4096 Mar  9 13:03 /root/testdir
$ sudo /bin/rmdir /root/testdir
$ sudo /usr/bin/vim
[sudo] password for root: 
$

Hope this helps.
