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.

pam_sss

PAM_SSS(8)							 SSSD Manual pages							PAM_SSS(8)

NAME

       pam_sss - PAM module for SSSD

SYNOPSIS

       pam_sss.so [quiet] [forward_pass] [use_first_pass] [use_authtok] [retry=N]

DESCRIPTION

       pam_sss.so is the PAM interface to the System Security Services daemon (SSSD). Errors and results are logged through syslog(3) with the
       LOG_AUTHPRIV facility.

OPTIONS

       quiet
	   Suppress log messages for unknown users.

       forward_pass
	   If forward_pass is set the entered password is put on the stack for other PAM modules to use.

       use_first_pass
	   The argument use_first_pass forces the module to use a previous stacked modules password and will never prompt the user - if no
	   password is available or the password is not appropriate, the user will be denied access.

       use_authtok
	   When password changing enforce the module to set the new password to the one provided by a previously stacked password module.

       retry=N
	   If specified the user is asked another N times for a password if authentication fails. Default is 0.

	   Please note that this option might not work as expected if the application calling PAM handles the user dialog on its own. A typical
	   example is sshd with PasswordAuthentication.

MODULE TYPES PROVIDED

       All module types (account, auth, password and session) are provided.

FILES

       If a password reset by root fails, because the corresponding SSSD provider does not support password resets, an individual message can be
       displayed. This message can e.g. contain instructions about how to reset a password.

       The message is read from the file pam_sss_pw_reset_message.LOC where LOC stands for a locale string returned by setlocale(3). If there is
       no matching file the content of pam_sss_pw_reset_message.txt is displayed. Root must be the owner of the files and only root may have read
       and write permissions while all other users must have only read permissions.

       These files are searched in the directory /etc/sssd/customize/DOMAIN_NAME/. If no matching file is present a generic message is displayed.
