Thanks Jan, When I am using the CApath, I do have the symbolic hash link (with ".0" at the end hash) linked to my ca-root.pem certificate file and ca-intermediate.pem certificate. Any other issues which could cause this issue? -----Original Message----- From: openssl-users [mailto:openssl-users-bounces@xxxxxxxxxxx] On Behalf Of Jan Just Keijser Sent: Monday, February 01, 2016 1:04 AM To: openssl-users at openssl.org Subject: Re: Certificate verification failure Yan, Bob wrote: > > Dear Sir/Madam, > > I have an application which acting as SSL server.

In it you should have placed the root and intermediate CA files using special names. Instead of using "ca.pem" you need to have a file "<hash>.0" , where <hash> is the output of "openssl x509 -hash -noout -in ca.pem" (and similarly for the intermediate CA file).
