title: Cloudify with Openstack:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
body: <p>I want to use Cloudify 3.1 with my Openstack in my company.</p>
  
  <p>Unfortunately, I had the prolem that the keystone authentication failed.
  When I see the log,it says,"SSL3_GET_SERVER_CERTIFICATE:certificate verify failed"</p>
  
  <p>I think it is HTTPS that make it failed. I see the curl below.</p>
  
  <pre><code>curl -i  'https://identity.example.com/v2.0/tokens' -X POST -H "Content-Type: application/json" -H "Accept: application/json" -H "User-Agent: python-novaclient" -d '{"auth": {"tenantName": "xxxx", "passwordCredentials": {"username": "xxxx", "password": "xxxxx"}}}'
  
  HTTP/1.0 200 Connection Established
  Proxy-agent: Apache
  
  curl: (60) SSL certificate problem, verify that the CA cert is OK. Details:
  error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
  More details here: http://curl.haxx.se/docs/sslcerts.html
  
  curl performs SSL certificate verification by default, using a "bundle"
   of Certificate Authority (CA) public keys (CA certs). If the default
   bundle file isn't adequate, you can specify an alternate file
   using the --cacert option.
  If this HTTPS server uses a certificate signed by a CA represented in
   the bundle, the certificate verification probably failed due to a
   problem with the certificate (it might be expired, or the name might
   not match the domain name in the URL).
  If you'd like to turn off curl's verification of the certificate, use
   the -k (or --insecure) option.
  </code></pre>
  
  <p>How can I make the curl succeed without using <code>-k</code> or <code>--insecure</code>?</p>
  
  <p>OR IF ANYONE HAS THE EXPERIENCE TO DO WITH openstack THAT KEYSTONE IS USING HTTPS WHEN INSTALLING Cloudify?</p>
