Hi, I am trying to connect Squid with Windows Server 2008 R2 active directory but its not working. I made a test environment and ran the following: /usr/lib/squid3/squid_ldap_auth -b "dc=matthew,dc=com" -h 192.168.2.3 -D "cn=vassm068,ou=IT,dc=matthew,dc=com" -w "Pa$$w0rd" -f "(&(objectClass=person)(cn=%s))" When I run this, I am getting the following error - WARNING, could not bind to binddn 'Invalid Credentials' ERR Success Do I need to install something on my AD server/squid to authenticate users? Do I need to install and configure Kerberos? I appreciate your help. Thanks Regards, Matthew
