I added a very special user "notebook", who will be able to
login in with a specific IP-/MAC-address only to the server.
The user is supposed to have file- and directory-rights only
to one single folder. All other inheritated rights like i.e.
to \PUBLIC or \LOGIN are not needed and not wanted. The user
is supposed - after EDir-authentification - to have only
access to this single folder.

I should know how to handle this in C1, I guess, but so far
I did not get a clue.

Any help or hint is highly appreciated.
