Hi Team, we are facing issues while performing Mutual SSL Authentication between Apache HTTPD Proxy and Server (using BW as Server) Scenario is: HTTP Client --- (http connection)---> Apache HTTPD --- (https connection) --->HTTPS Server. Server side authentication is working fine on both Linux and Windows environment. However, Mutual SSL authentication is only working on Windows, and facing issues while implementing same logic on Linux.
On Windows we are using the latest Apache HTTPD Proxy version 2.4.10. And for Linux we are using Apache HTTPD Proxy version 2.2.26. The problem appears to be that HTTPD does not include the issuer details while presenting its certificate to the server, so probably its failing chain verification. We have tried many options found on the net like including the flag “SSLOptions
+ExportCertData”, but nothing seems to help. On Linux HTTPD is not sending the full certificate details back to the server Please find below the Logs for both Windows(success) and Linux(error) Environments: Windows Server version: Apache/2.4.10 (Win64) Apache Lounge VC11 Server built: Jul 17 2014 12:58:29 Logs: [Wed Jun 03 16:21:18.307618 2015] [ssl:debug] [pid 6580:tid 964] ssl_engine_kernel.c(1517): [remote 127.0.0.1:9099] AH02277: Proxy client certificate callback: (Proxy:hostname) AH02278: no
