[Olivier CALVANO <o.calvano@xxxxxxxxx>]

Hi Amos,

Thanks for your help,

buit if i don't put the line http_access deny !Group_Allowed, user not in the group connect connect

and access to all internet

my config:



######################################################################
# ACL pour les Droits d'accès d'apres l'Active Directory
######################################################################
acl Authentification proxy_auth REQUIRED
http_access deny !Authentification
acl Group_Allowed external AD_Group Internet-Access
http_access allow Group_Allowed
#http_access deny !Group_Allowed
######################################################################

#always_direct deny Authentification
http_access allow Lan
http_access deny all

To check group membership, Squid must first know what user login
credentialsare being checked.

As Group_Allowed uses %LOGIN format code it will perfom 407 auth if it
is used on any line and login is not yet provided, or do 407
re-authentication whenever it is last ACL named on a deny line. In order
to give the user the chance to provide credentials that will pass the test.

In this particular config setup use "deny all" instead of "deny
!Group_Allowed".
