Apache SNI, 2 domínios, 2 certs, resolve a mesma raiz de documento

Question

Atualmente, estou seguindo o seguinte guia:

A instalação até agora está livre de problemas. Estou usando dois certificados de classe 1 que registrei no link . Cada um é mapeado para seu próprio domínio (correto).

O problema é este: ir para qualquer domínio sob https resolve para o mesmo documento raiz, ou seja, se eu vou para link , eu corretamente venha para a raiz do doc indicada em sua configuração do VirtualHost. No entanto, se eu acessar o link , serei enviado para a raiz de backend.domain2, permanecendo o URL intacto, com um aviso de que o certificado SSL é inválido. Uma inspeção do certificado "inválido" revela que é aquele conectado ao backend.domain2.

O que estou fazendo de errado aqui? as configurações do VirtualHost para os dois domínios estão abaixo:

<IfModule mod_ssl.c>
        <VirtualHost *:443>
        # The ServerName directive sets the request scheme, hostname and port that
        # the server uses to identify itself. This is used when creating
        # redirection URLs. In the context of virtual hosts, the ServerName
        # specifies what hostname must appear in the request's Host: header to
        # match this virtual host. For the default virtual host (this file) this
        # value is not decisive as it is used as a last resort host regardless.
        # However, you must set it for any further virtual host explicitly.

Answer 1

Isto ..

ServerName mail.domain1.se
ServerAdmin [email protected]
ServerAlias www.mail.domain1.se

.. e isso ..

ServerName backend.domain2.com
#ServerAlias www.domain2.com

.. ambos não combinam com o nome do host que você está dizendo que está visitando, https://domain1.com . Esses nomes de host precisarão corresponder exatamente ao que está sendo solicitado no navegador para que o certificado correto seja exibido ao cliente.

    

Answer 2

Só para ter certeza, você está usando uma versão do navegador que suporte o SNI? Segundo a Wikipedia,

 As of November 2012, the only major user bases whose browsers do not support 
 SNI appear to be users of Android 2.x (default browser)[2], Internet Explorer 
 on Windows XP[3][4] and versions of Java before 1.7 on any operating system.[5]
