I need to block/prevent automount of usb pendrive non-root users in SLED 10SP2.
It can be from gnome settings with gconftool or from nautilus options, but these are settings that the user can set their permissions (not what I need)
In SLES10SP2 I could set to ask the root password every time you insert a flash drive, setting with the command polkit-gnome-authorization.
I tried to read the hal configuration files, to do the same .. but I'm walking around without achieving anything ..

How I can prevent normal users (non-root) mount pendrive?

Thank you for reading ..
