I am running the openssl tool from the FIPCA utility kit to check the server certificate. I am getting error 20 and 21. The certificate is retrieved successfully from the server and displayed on the Dos console. However, error 20 and 21 is shown prior to the certificate contents display and "Verify return code: 21 (unable to verify the first certificate)" message is shown as the last message. C:\FIPS-CA\ssl_dev>openssl s_client -connect 172.30.128.193:443 -CAfile C:\Windows\System32\CertSrv\CertEnroll\TrustedCA.txt I installed the certificate in local machine which should not be required to pass this test.
