GNUTLSClientVerify não bloqueia CAs não reconhecidas

Question

Eu instalei o Apache no Ubuntu, instalei o módulo GNUTLS e tudo funcionou bem:

root@ilnwad15:~# apache2 -v
Server version: Apache/2.2.22 (Ubuntu)
Server built:   Jul 12 2013 13:37:15

Agora, quero que na porta 1443, se a CA do certificado de cliente não for a CA no meu servidor, ela será bloqueada.

Foi assim que eu configurei no /etc/apache2/apache2.conf

Listen *:443
Listen *:1443
<VirtualHost *:443>
    GnuTLSEnable on
    GnuTLSKeyFile  /etc/apache2/certs/ilnwad15.tlv.sap.corp.key
    GnuTLSCertificateFile  /etc/apache2/certs/ilnwad15.tlv.sap.corp.crt
    DocumentRoot /disk2/var/www/html
    GnuTLSPriorities EXPORT
    ServerName      ilnwad15
</VirtualHost>

<VirtualHost *:1443>
    GnuTLSEnable on
    GnuTLSKeyFile /etc/apache2/certs/ilnwad15.tlv.sap.corp.key
    GnuTLSCertificateFile /etc/apache2/certs/ilnwad15.tlv.sap.corp.crt
    GnuTLSPriorities EXPORT
    GnuTLSClientCAFile /etc/apache2/certs/ca.pem
    GNUTLSClientVerify require
    DocumentRoot /disk2/var/www/html
    ServerName ilnwad15
</VirtualHost>

O que ele faz agora é, ao enviar uma solicitação sem certificado, receber um erro interno.

[root@ilnwadv56 ~]# wget --save-headers --no-check-certificate HTTPs://ilnwad15.tlv.sap.corp:1443

No entanto, quando a solicitação tem um certificado de que sua CA não corresponde à CA do servidor, recebo 200 OK de Internet Explorer e não 403 Forbidden. Ao fazer isso de wget , estou obtendo o failed: Service Unavailable to establish SSL connection.

[root@ilnwadv56 ~]# wget --save-headers --no-check-certificate --certificate=/sapmnt/accad/other/client.crt --private-key=/sapmnt/accad/other/client.key HTTPs://ilnwad15.tlv.sap.corp:443

Alguém tem uma ideia de qual é o meu erro? Agradecemos antecipadamente.

OK, primeiro de tudo, obrigado por todos, que tentaram ajudar (especialmente para @MadHatter). O problema é que usei um proxy, então tive que unset https_proxy e o problema foi resolvido.

Neste momento, funciona corretamente. Ao enviar um certificado fictício (por não dar nenhum certificado através de wget )

wget --save-headers --no-check-certificate HTTPS://ilnwad15.tlv.sap.corp:1443
--2013-12-22 10:37:02--  https://ilnwad15.tlv.sap.corp:1443/

Ao fornecer um certificado correto.

wget --save-headers --certificate=/sapmnt/accad/other/ilnwad15.tlv.sap.corp.crt --private-key=/sapmnt/accad/other/ilnwad15.tlv.sap.corp.key --no-check-certificate HTTPS://ilnwad15.tlv.sap.corp:1443
