I m trying to install a root certificate in my cent OS box. I did the following
Enable the dynamic CA configuration feature: update-ca-trust force-enable
Add it as a new file to /etc/pki/ca-trust/source/anchors/ cp foo.crt /etc/pki/ca-trust/source/anchors/
Use command: update-ca-trust extract Then I m running below command to verify the certificate.
openssl s_client -connect my_AD_server_IP:636 -CApath /etc/ssl/certs
Bur getting below error(This is part of the error)
Verify return code: 20 (unable to get local issuer certificate)
