no su password prompt

[nyvietvet]

I am running PCLInuxOS2010.07, kernel 2.6.33.5 with the KDE 4.5 desktop.

Since I set up autologin for myself as user, not root, I am no longer prompted for an su password when launching Synaptic, or BleachBit Root.  If this is not easily solved, should I just disable autologin?

Thanks in advance for any assistance.

This is the best damn Linux forum around, hands down!  Kudos.

Did you perchance make any edits to the sudoers file?

[nyvietvet]

Not that I'm aware of, JohnBoy.  I am more of a GUI person, but great question.

Thank you.

Just in case you are logged in as root check the result from
whoami

It should return your user name.

[nyvietvet]

I did that earlier, JohnBoy; no joy.  I just tried disabling autologin from the control center, rebooted, same result.  I was not prompted to sign in, GUI loaded, Synaptic launched with no prompt.

what is the output of the following command? (copy and paste it on the terminal)

cat /etc/group | grep `whoami`

[nyvietvet]

[bill@localhost ~]$ cat /etc/group | grep `whoami`
lp:x:7:mysql,bill
floppy:x:19:mysql,bill
cdrom:x:22:mysql,bill

Check what groups your user is a member of ........  can do it through PCC - System - Manage Users - select your user - Edit and check the groups tab

Your user should not be a member of root or wheel groups .....

JohnBoy,
he is a member of all the groups mentioned in the result of the command he gave above

nyvietvet,
strange problem, i have autologin set to a normal account and dont have the problem you are having.

it could be that those two programs have messed up permissions or your system has messed up permissions.

from the same terminal, type this command and give its output here(copy and paste it again)

mkdir /test ; ls -l /test

[nyvietvet]

[bill@localhost ~]$ mkdir /test ; ls -l /test
mkdir: cannot create directory `/test': Permission denied
ls: cannot access /test: No such file or directory
[bill@localhost ~]$ su
[root@localhost bill]# mkdir /test ; ls -l /test
total 0

Sorry ...  had missed your post ......  delay between writing and sending ....

I think a lot at the sudoers file is in order ....

[muungwana]

your normal user couldnt create the folder in root's folder and that shows the permissions are in order. i too suspect the problem could be in your sudoers file

log in root on the terminal and then type this command and paste its content here:

cat /etc/sudoers

[nyvietvet]

[root@localhost bill]# cat /etc/sudoers
# sudoers file.
#
# This file MUST be edited with the 'visudo' command as root.
#
# See the sudoers man page for the details on how to write a sudoers file.

# %users  ALL=/sbin/mount /cdrom,/sbin/umount /cdrom

I cant see any error in your sudoers file and dont see how setting autologin will set synaptic to start without asking for root's password.

..very odd ..

There is some sort of a mechanism for keeping root's privileges for a while after it is requested for the first time. maybe this feature accidentally turned on? try to create another account and log in using it and see if the problem is there too
