Active Directory Groups

[piotrl]

HI All

I use:
pfsense 2.0.3
squid 2.7.9 pkg v.4.3.3
squidGuard 1.4_4 pkg v.1.9.5

I configure load balancing and failover but have problem with AD.
After instal squid + SquidGuard and configure proxy server + authentication LDAP, all users conected to the network do not have access to the internet.

I added the proxy filter AD group and set all the permissions allow.

I forgot to say that I am using Active Directory groups and would like to one group of users have access to the Internet and the other does not.

My configuration in Attachment

Anyone can help ?
