Subject [users@httpd] Apache proxy as client to SSL server
Date Thu, 31 Mar 2005 09:44:03 GMT

<body><div style="display: block; font-family: Arial; font-size: 12px;">Hi,<br>
At this moment we are using a apache configured as proxy to another
secure apache server, but now for security reasons only https is not
enough. We must now use certificates.<br>
In my mind this means our apache proxy is the client to the secure
server and thus needs a client certificate, I tried to configure this
in apache <br>
(snippet from httpd.conf)<br>
&nbsp;&nbsp;&nbsp; SSLProxyEngine On<br>
&nbsp;&nbsp;&nbsp; SSLProxyMachineCertificateFile ssl/client.crt<br>
When I try to start the apache server then the following message appears in the error log:<br>

incomplete client cert configured for SSL proxy (missing or encrypted private key?)<br>
Does somebody know how to solve this problem or have a complete
procedure for installing a client certificate in Apache (preferrable
also how to create the client certificate)<br>
