Dispatcher SSL configuration on Linux

Experts,
The SSL configuration instructions for dispatcher are not working and there must be something missing or incorrect.
Please help!
--------------------------------
Situation:
Dispatcher was configured and tested on port:80 - works fine. Now switching to SSL:

1) Downloaded dispatcher that supports SSL (dispatcher-apache2.4-linux-x86-64-ssl10-4.1.9.tar)

2) Replaced the dispatcher library and re-link the mod_dispatcher.so to point to the new dispatcher library

3) Linux OpenSSL is version 1.0 -> Relinked to older version to support dispatcher:

“ln -s libssl.so.10 libssl.so.0.9.8” and “ln -s libcrypto.so.10 libcrypto.so.0.9.8”

4) Generated self-signed certs <myserver>.crt and <myserver>.key

5) Updated httpd.conf:

Listen 443

<VirtualHost <myserver>:443>
  ServerName  <myserver>
  DocumentRoot /usr/share/httpd
  <Directory /usr/share/httpd>
    <IfModule disp_apache2.c>
      SetHandler dispatcher-handler
    </IfModule>
    AllowOverride None
  </Directory>
  SSLEngine on
  SSLCertificateFile /etc/httpd/ssl/<myserver>.crt
  SSLCertificateKeyFile /etc/httpd/ssl/<myserver>.key
</VirtualHost>

6) Error on restarting apache:

"Invalid command 'SSLEngine', perhaps misspelled or defined by a module not included in the server configuration"
---------------------------------------------------------------------------------
It seems like we need to load apache ssl module in addition to dispatcher ssl module, right?
Is "LoadModule ssl_module modules/mod_ssl.so" required?
Does anyone run Dispatcher on SSL on Linux? Can you share your httpd.conf settings?
Thanks a lot!

Hi, are the tweaks that you mentioned not documented here?  http://docs.adobe.com/docs/en/dispatcher/disp-ssl.html

If not, if you tell me what you did I can see about adding the information to that page.

 

thanks,
scott

      Thanks! It seems like the "mod_ssl.so" is implicitly loaded by "mod_dispatcher.so" and no explicit directive is required.
      Just make sure "mod_ssl.so" is in the modules directory. I got it working with a few tweaks.
      It seems like the dispatcher documentation needs to be updated with more details about the SSL configuration.
      Thanks, Alex

        Well, I was hoping someone has Dispatcher-6.1 working on SSL on Linux. A httpd.conf sample would help!
        PS: Dispatcher's README.txt is dated 2013! :-)

            On Monday  I will reach out to internal Adobe people to see if anyone has encountered  this.

          Hi,

          It's likely that you don't have the SSL module loaded. Please add this statement to your httpd.conf:

          LoadModule ssl_module modules/mod_ssl.so

          kind regards,
          Jörg

            If docs are not working; please file a ticket. A support agent will help here.

            I am using

            Linux - Ubunt 14 X64 , [Linux ubuntu 4.2.0-27-generic #32~14.04.1-Ubuntu SMP Fri Jan 22 15:32:26 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux]

            Dispatcher version - dispatcher-apache2.4-linux-x86-64-ssl10-4.1.12/

            Any pointer what could be causing this.
