Eu tenho tentado fazer o squid rodar com o kerberos auth por alguns
dias, mas estou com algum problema. O problema foi perguntado e respondido
muitas vezes na lista de usuários do squid e na web, eu li
todos eles, e tentou resolver o problema. Mas ainda sem sorte.
Não sei por que o cliente tenta autorizar com o NTLM em vez do Kerberos, e eu realmente aprecio se você me explicar como inspecionar o motivo e como corrigir o problema.
Aqui estão alguns dos meus arquivos de log e testes.
(arquivos de configuração são preparados exatamente como no wiki;

Eu testei kerberos no lado do servidor com
--> klist
Ticket cache: FILE:/tmp/krb5cc_0
Default principal: [email protected]
--> kinit -V -k -t /opt/labris/etc/labris-webcache/HTTP.keytab
HTTP/test2008.labristest.com
Authenticated to Kerberos v5
Eu capturei os pacotes com wireshark como sugerido alguns dos
soluções anteriores, parece que o cliente ainda tenta autenticar
com o NTLM enquanto queremos usar o kerberos.
Aqui estão algumas das partes do log wireshark;

Por favor, veja-me como um novato
Eu realmente aprecio uma solução detalhada para fazer o squid trabalhar com
kerberos.
Obrigado antecipadamente.
