[squid-users] working squid_ldap_group examples

Hello list,

does anybody have some working examples for me? I'm trying to grant internet access for all users within a specific ldap group (ADS).

This is my call:
/usr/lib64/squid/squid_ldap_group -b "cn=Internet,ou=User_Groups,dc=test,dc=local" -D "cn=ldap,ou=Users,dc=test,dc=local" -w 'PASSWORD' -f "(&(objectClass=person)(sAMAccountName=%u)(memberOf=cn=%g,ou=User_Groups,dc=test,dc=local))"� -h srv-dc02.test.local -K -R

But when I test some usernames with this tool, I'm always getting the output "ERR".

Thanks for helping.
