Connecting to host jboss-testvm.na.kfy.com:443
ERROR: The SSL certificate of jboss-testvm.na.kfy.com could not be verified
Certificate issuer data: /C=US/O=YouCorp/OU=Operations/CN=jboss-testvm.na.kfy.com

Configuration Info:

OpenSSL Configuration:
* Version: OpenSSL 1.0.1l 15 Jan 2015
* Certificate file: C:/projects/openssl/knap-build/var/knapsack/software/x86-windows/openssl/1.0.1r/ssl/cert.pem
* Certificate directory: C:/projects/openssl/knap-build/var/knapsack/software/x86-windows/openssl/1.0.1r/ssl/certs
Chef SSL Configuration:
* ssl_ca_path: nil
* ssl_ca_file: "C:/opscode/chef/embedded/ssl/certs/cacert.pem"
* trusted_certs_dir: "c:\\users\\yuj\\chef-repo\\.chef\\trusted_certs"

TO FIX THIS ERROR:

If the server you are connecting to uses a self-signed certificate, you must
configure chef to trust that server's certificate.

By default, the certificate is stored in the following location on the host
where your chef-server runs:

  /var/opt/opscode/nginx/ca/SERVER_HOSTNAME.crt

Copy that file to your trusted_certs_dir (currently: c:\users\yuj\chef-repo\.chef\trusted_certs)
using SSH/SCP or some other secure method, then re-run this command to confirm
that the server's certificate is now trusted.
