dc1 is the hostname of oure windows 2003 domain controller, so dc=dc1 should be correct. i changed the auth_param basic value to this: squid_ldap_auth -b "ou=Benutzer,ou=99,dc=dc1" -D "cn=Administrator,ou=Domanen-Admins,dc=dc1" -w /etc/password-file -f "SamAccountName=%s" when i try to use this commando from the command line, i receive the following error when i enter a working user/password combination: squid_ldap_auth: WARNING, could not bind to binddn 'Can't contact LDAP server' ERR i think this should be a problem with the user Administrator in the ou "Domanen-Admins" > -----Ursprungliche Nachricht----- > Von: Henrik Nordstrom [mailto:hno@xxxxxxxxxxxxxxx] > Gesendet: Montag, 30.
