I solved this problem 3am today. After reading entirely access.log cache.log and squid.out, i decided to test if anything could connect via tcp/ip to the squid daemon, on other ports than 3128, and discovered that the packets, even if the connection started from localhost. Searching google, discovered that stupid process SeLinux, on my Fedora Core 5 was blocking communication between helpers and squid. Just a question of reconfiguring SeLinux to permit communication to squid process and works perfectly, including ldap_group helper. Tks for the attention anyway, and sorry for any inconvenience P.S.:That's the problem on using another distro, but i couldn't get my SuSE10 work with my VIA VT8251 Sata controller. But it's another problem.... Tks...

Odd.. never seen that before when the browser is configured to use the proxy, and certainly not in relation to authentication. Are you sure the browser is properly configured to use the proxy? Please do testing using Firefox. MSIE is a bit odd... Regards Henrik
