The university where I work have 60000 users and 14000 computers. :)

I do. If I have private files on my USB stick, I do not want other
users to have read access to it.
The current system do not scale, and fail to keep personal files
private, and for these reasons I believe we must switch to a system
that work.
In addition, storing OS-specific group information in LDAP will make
the LDAP database hard or impossible to use across operating systems,
and that is also a problem for large installations.

I believe he would just need to ssh into the machine, then send a dbus
event to umount and mount it, to get full access, would he not? hal
do not know which of the users in the plugdev group should be allowed
to mount the device, and will grant all of them access.
