[SOLVED]Mounting usb drives "not authorized" with thunar-volman (XFCE)

Question

Hi,
I'm new to Arch (even though I must be approximately at my 15th try at installing it properly) and I have a problem with thunar-volman.
Whenever I log in as user, and try to mount a usb drive with thunar, let's say I want to plug a drive labeled Ext3_8Go, I get the same message in a pop-up window : "Failed to mount Ext3_8Go (or anything close, not in English in the text), not authorized (that part is in English)"
My install is :
- net install
- partitions : 9Go for /, no swap, no separate /home
- packages : base and base-devel. The only modifications in the package list is that I remove ppp, pcmciautils, and xfsprogs.
- config : at the install stage I only modify rc.conf to change LOCALE and HOSTNAME, and pacman's mirrorlist to allow all French mirrors in addition to the one at the top.
When the usb installation is over, I run this script :
"installation_xfce.sh"  (there may be some errors left, I modify this script as I learn) :
#!/bin/bash
# expected environment : freshly installed archlinux, login : root.
echo "Are you connected to internet ? If not, please Ctrl+C and reload this script when connected"
echo "Otherwise, press ENTER to continue installation"
read var_dummy
echo "Creation of the user : please type in your user name :"
read var_username
useradd -u 1000 -g users -G audio,lp,storage,optical,video,wheel,games,power,network -d /home/$var_username/ -s /bin/bash -m $var_username
echo "You will now be asked to create the password for this user:"
passwd $var_username

I can mount as a user, no password asked, with :
udisks --mount /dev/sdb2
but the GUI method tells me "not authorized".
"groups user" outputs :
lp wheel games network video audio optical storage power users
the command "ck-list-sessions" outputs :
Session2:
unix-user = '1000'
realname = ''
seat = 'Seat1'
session-type = ''
active = TRUE
x11-display = ':0.0'
x11-display-device = '/dev/tty7'
display-device = ''
remote-host-name = ''
is-local = TRUE
on-since = '2011-08-15T08:56:03.716103Z'

For those who don't have time to read the installation script, DBUS is in the DAEMONS list of rc.conf, and .xinitrc launches : exec ck-launch-session startxfce4
Any idea ?

Thanks a lot !
That worked !
I stumbled across this part of the wiki several times before, but didn't really understand so I had not tried.
If anyone's interested in the script, here's the corrected version :
#!/bin/bash
# expected environment : freshly installed archlinux, login : root.
echo "Are you connected to internet ? If not, please Ctrl+C and reload this script when connected"
echo "Otherwise, press ENTER to continue installation"
read var_dummy
echo "Creation of the user : please type in your user name :"
read var_username
useradd -u 1000 -g users -G audio,lp,storage,optical,video,wheel,games,power,network -d /home/$var_username/ -s /bin/bash -m $var_username
echo "You will now be asked to create the password for this user:"
passwd $var_username

The important part of the script to solve the problem is :
cat > /home/$var_username/.xinitrc << EOF
#!/bin/sh
# ~/.xinitrc
# Executed by startx (run your window manager from here)
exec ck-launch-session startxfce4
thunar --daemon &
