Bronze = 32kb bandwith 5. other = 32kb bandwith i use squid_ldap_auth like this auth_param basic program /usr/local/squid/libexec/squid_ldap_auth -b o=tes,c=id -f (&(uid=%s)(description=p6)) -h 10.1.1.1 i add attribute description=p1 until p5 to define internet group in ldap server and i set 5 proxy server for each group now i want to join 5 proxy server into single proxy server the problem parameter auth_param basic program is single line we can't add the same parameter from http://markmail.org/message/kqhn2j2wohmx4hjz#query:multiple%20squid%20ldap%20auth+page:1+mid:vgaa53tcjnol7psl+state:results i imagine that i must create 5 groups in ldap add parameter external_acl_type ldap_group %LOGIN /usr/local/squid/libexec/squid_ldap_group then create acl proxy_groups external ldap_group diamond gold silver bronze other then i create delay pools for bandwith management to each group anny suggestion for the best solusion?
