I didn't want to manually have to enter each user into /etc/fstab (lazy, I
know :) ), but
I found a workaround.

I found mount.cifs./umount.cifs and chmod-ed them to u+s.  I've established
mount points
that they own, and the bash_logout script can mount their shares and then
sync the windows
and linux sides.

I don't think that's a security issue - they can only mount their shares to
their designated mount
points, and they don't have any extra rights as users...
