Hello, I have a version: Server version: Apache/2.4.38 (Win64) Apache Lounge VC15 Server built: Feb 28 2019 11:40:54 Server's Module Magic Number: 20120211:83 Server loaded: APR 1.6.5, APR-UTIL 1.6.1 Compiled using: APR 1.6.5, APR-UTIL 1.6.1 SSLCertificateFile C C is son of authority A SSLCertificateChainFile is not defined SSLCACertificateFile contains A. And in the Certificate chain returned in openssl s_client -connect -showcerts is returned the A If SSLCACertificateFile is not defined, A is not returned. Why Apache server behaves in this way?
