Estou tendo erro 407 (accesso negado por falha de autenticacao) no squid pai.
Tenho q usar um proxy pai (q pede por autenticacao) e um proxy filho numa fabrica local com intencao de poupar banda.

sobre estas circunstâncias, tudo roda OK:
1º no filho adicionando linha 'cache_peer 172.17.50.2 parent 3128 3130 login=loginass no-query default", tudo roda OK, mas é indesejável, pq sempre assumirá o mesmo usuario/senha;
2º no pai, desabilitando autenticacao, tudo roda OK, entao o problema está na autenticação...;
3º no navegador cliente (Internet Explorer), seto proxy pro pai, pede por usuario/senha e autentica OK, entao o problema nao esta na autenticacao nem nas permissoes dos arquivos de autenticacao.

Estou usando RedHat 9 com squid 2.5-STABLE1.2 nos dois proxys. O cliente navegador estou usando IE do Win Server 2003.

alguma sugestao?!?!? já postei em vários foruns e não obtive nenhuma resposta...
