I'm currently trying to decide on a way for out kids to hand in their work to their teacher securely, that is without other kids being able to osteal it and pass it off as their own.
We have a setup whereby each teacher has a folder on a network share to which they have full control, the pupils user group has write and list folder contents. creator owner has full control. so in effect they can 'hand in' their work and make alterations to their own files if they wish, but they cannot open other kids files.
the problems arise however when teachers copy their folders off onto laptops, usb sticks etc take them home and mark them then dump them back, and hey presto the kids lose creator owner on their files and cant open them. and the teachers calls me up flapping like a dememnted monkey on crack.
how do you do it?
