My setup has a ROOT CA and 3 level of Sub CA's. I have generated apache web server and client certificates from every the ROOT and Sub CA's.
I have configured my
APACHE web server for client certificate (mutual) authentication. I have generated the apache web server certificate and client certificates from the ROOT CA with proper
extensions. In case of Root CA, it works well. Mutual authentication works fine.
In case of Sub CA, the apache web server certifictae and client certificates are generated by SubCA with the same extensions/profile as in case of ROOT CA. But when i try to authenticate users from Sub CA's then following error occurs "
unhandled critical extension". SSLCACertificateFile contains the concatenated certifcates of all the CA's( issuing CA certtificate is at top and Root ca certificate is at bottom of this file)
Here is my vhost fileNameVirtualHost *:80

//chain.pem contains all the
