Azure

I have successfully configured an Extended-Validation Certificate on an Azure Website following this article:

http://www.windowsazure.com/en-us/documentation/articles/web-sites-configure-ssl-certificate/

The main (non-technical) stakeholder of the web application went through great lengths to validate that our site is secure. He went to this site to check the validity of our SSL: http://www.whynopadlock.com/

The site throw the following error: `SSL verification issue (Possibly mis-matched URL or bad intermediate cert.). Details: ERROR: no certificate subject alternative name matches``

The certificate is installed using IP Based SSL instead of SNI. This is done this way because some site visitors still use Internet Explorer 8 on Windows XP, which has no support for SNI and throws a security warning.

Is my certificate correclty installed? I received three .CRT files from my SSL provider:

PrimaryIntermediate.crt
SecondaryIntermediate.crt
EndCertificate.crt

This is how I exported our certificate as a .PFX file to Azure:

openssl pkcs12 -export -out myserver.pfx -inkey myserver.key -in myserver.crt

My RHEL5 box currently has 0.9.8e and Apache version httpd-2.2.26-2.el5. According to a same question here it's not a good idea to replace the original version… >>> More
