Hi We're using squid with squid_ldap_auth in schools. Now one teacher asked me, if it is possible to block more than one login with the same account from different workstations. So "foo" could login on client 192.168.0.3 but not again at the same time on 192.168.0.4 At this time the auth_param line looks like: auth_param basic program /usr/sbin/squid_ldap_auth -v 3 -b ou=people,dc=example,dc=com -f (&(!(internetDisabled=yes))(! (gidNumber=503))(uid=%s)) -u uid ldap Is there a way to get this feature included without writing a new auth_script? Thanks! Lars
