Enabling Client Authentication

Enabling Client Certificate Authentication on Apache web server

To enable Client Certificate Authentication on Apache 1.3 you will need to obtain your own Digi-ID™ [1] Client Certificate, Certification Authority Certificate Chain (CA Chain) and setup Authentication Rules using the httpd.conf file and Apache configuration directives.

2.1 Obtaining the Digi-Sign Certification Authority Certificate Chain

Since Apache is using the SSLCACertificateFile configuration directive to point to the Certification Authority Chain for both SSL Certificates [2] and Client Certificate Authentication, assuming you have already setup this directive in step 1.2.2, you can omit this section.
If however, you have not obtained/received the ca-bundle file, you may download it from the following URLs:
