/mnt/cdrom

Hi,

I work in a school and have just deployed linux machines in one room,
kiosk is working fantastically apart from one problem. Where I have
locked down the machines to not allow access to the '/' directory,
this has now lead to /mnt/cdrom (I'm using Mandriva) to not work
either.

Now this is weird as they can access the cdrom and see the contents,
but if they try and run anything, for example one teacher had a html
website on his cdrom, it states access denied.

I know its something to do with the previous rights I put in place but
am not sure how to word it.

I can attach my list if needed.

Thanks,

Jo
