I need help figuring out where the computerNames are coming from. As I mentioned before, I thought I had eliminated the computerNames by the squid_ldap_auth helper above. I have more than 400 users (and growing) and would like to keep their userNames only in the userlists. When the computerName is logged, the end user ends up using the default ACL which is more restrictive on outbound browsing, resulting in trouble tickets to fix the problem. auth_param negotiate program /usr/local/squid/libexec/squid_kerb_auth auth_param negotiate children 30 auth_param negotiate keep_alive on url_rewrite_program /squidGuard/redirector-id.pl url_rewrite_children 8 url_rewrite_concurrency 10 acl AUTH proxy_auth REQUIRED and here is the rest of my basic auth: auth_param basic children 15 auth_param basic realm SquidGuard Authentication auth_param basic credentialsttl 8 hours http_access allow localnet http_access allow AUTH Thank you, -Dustyn
