[cups.general] rights to print

[Patrick DUBAU]

Hi,
i have cups 1.1.22-8 installed i want to restric access to the web 
interface of cups so that each time someone try to access at the home 
page he has to log in.
So  i put  :
    <Location />
    AuthType Basic
    AuthClass System
   
    Order Deny,Allow
    Deny From All
    Allow From  192.168.251.*
    </Location>
=> ok login and password are asked each i do a http://x.x.x.x:631
But know the problem is that nobody can print. The problem must be in 
the jobs section so i put

<Location /jobs>
#
# You may wish to limit access to job operations, either with Allow
# and Deny lines, or by requiring a username and password.
#

AuthClass Anonymous
AuthType None
Order Deny,Allow
Deny From All
Allow From  192.168.251.*
</Location>
But users still can not print where is the trick ?
Thanks for any help
