[sudo-users] Allow the dir creation to one level only

[Moisés Barba Pérez]

Hi:

   I would like to create a rule in sudoers file to allow an user the mkdir
comand. I'm looking for the way to limit the dir creation to one level, for
example:

1. The user can create a dir in /data: sudo mkdir /data/user
2. The user *can't* create a subdir un /data: sudo mkdir /data/user/mydir (I
want to avoid this)

   I have been playing with the wildcards in the manual but I can make a
rule for this funcionality.

Regards,

Moisés.
