Apache SNI, 2 domains, 2 certs, resolves to same document root

Question

I am currently following the following guide: https://www.digitalocean.com/community/articles/how-to-set-up-multiple-ssl-certificates-on-one-ip-with-apache-on-ubuntu-12-04

Setup so far has been problem free. I am using two class 1 certificates that I have registered at http://www.startssl.com/?app=21. Each is mapped to its own (correct) domain.

The problem is this: going to either domain under https resolves to the same document root, i.e. if I go to https://backend.domain2.com, I correctly come to the doc root indicated in its VirtualHost configuration. However, if I go to https://email.domain1.com, I get sent to the root of backend.domain2, URL remaining intact, with a warning that the SSL certificate is invalid. An inspection of the "invalid" certificate reveals that it is the one connected to backend.domain2.

What am I doing wrong here? the VirtualHost configs for both domains are below:

<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.

I am having the exact same issue on 2.4.7 (Ubuntu LTS). Did you find a solution? — ColinM, Jan 07 '16 at 04:49

This..

ServerName mail.domain1.se
ServerAdmin christopher.svanefalk@gmail.com
ServerAlias www.mail.domain1.se

..and this..

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

..both don't match with the hostname you're saying you're visiting, https://domain1.com. These hostnames will need to match exactly with what's being requested in the browser for the correct certificate to be served to the client.

domain1.com etc was supposed to be a generic item, the real domain name is actually backend.domain2.com etc. I will update my code so there is no confusion. – csvan May 02 '14 at 08:27
When you update, please use `example.com` and `example.org` instead of `domain1.com` etc. It's rude to use domains owned by someone else. – Jenny D May 02 '14 at 09:38
@chrsva Can you add the output of `apachectl -S` as well? – Shane Madden May 02 '14 at 15:38
@JennyD - respectfully, domain1.com and domain2.com are not owned by anyone, or I would not have used them. – csvan May 03 '14 at 05:57
s/not owned/not currently owned/ - example.[com|net|org] are specifically set aside for this purpose. Of course, it would have been better still if you hadn't obfuscated your domain name at all; that way the people spending their free time trying to help you would have been able to verify how it looks from the client. – Jenny D May 03 '14 at 06:20

Just to make sure, are you using a browser version that supports SNI? According to 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]

or a more detailed list here: http://en.wikipedia.org/wiki/Server_Name_Indication#Client_side

I have tried it across 3 separate browsers - the latest Chrome, Firefox and Konqueror. All yield the same issue, and all support SNI. I am rather certain it is a server problem. – csvan May 02 '14 at 08:26
