[FUG-BR] duvida acl squid

[Cleyton Bertolim]

Boa tarde Lista!

ha algum tempo atraz montei um servidor proxy com o squid e o pessoal
tinha que se autenticar no proxy pra poder navegar na internet, e
tambem tinha um grupo de nomes de usuarios pra cada setor daquela
empresa, entao cada setor so navegava nos sites que eram realmente
liberados. Segue um pequeno trecho do squid.conf deste lugar que esta
funcionando perfeitamente:

################################
### AUTENTICACAO DE USUARIOS ###

auth_param basic children 10
auth_param basic realm DIGITE SEU USUARIO E SENHA

auth_param basic casesensitive on

AGORA ESTOU TENTANDO FAZER A MESMA COISA EM OUTRA EMPRESA, SO QUE O
PESSOAL ESTA USANDO PROXY TRANSPARENTE E NAO ESTAO FAZENDO
AUTENTICACAO DE USUARIOS, ENTAO O CONTROLE É FEITO APENAS PELOS
ENDERECOS IP'S.
MAS NAO ESTA DANDO CERTO!
SO ESTA PASSANDO PRA ACESSAR A INTERNET OS USUARIOS QUE TEM ACESSO
TOTAL PRA INTERNET. OS IP'S QUE DEVERIAM TER ACESSO HA ALGUNS SITES
COMO: GOOGLE.COM.BR, YAHOO.COM.BR ETC, NAO ESTAO CONSEGUINDO ACESSAR
NADA!!! NAO SEI O QUE ESTA ERRADO! JA PROCUREI NA NET E NA FUG SOBRE
ESSA DUVIDA MAS NAO ENCONTREI NADA!!!

ESTOU ENCAMINHANDO NESTE EMAIL O MEU NOVO SQUID.CONF E ALGUNS TRECHOS
DOS MEUS ARQUIVOS PARA ACL'S:
