    Hi Bjorn<br>
    thanks for suggestion. It still doesn't work, but I've found the
    reason.<br>
    First of all, I do not need the end-user communicates with the
    services glance/nova/neutron/cinder with SSL; I just need the
    services themselves listen on plain HTTP. What I need is that the
    services  can talk to Keystone/SSL (so SSL ativated only for the
    Keystone component).<br>
    What it was missing, was the parameter:<br>
    <br>
    neutron_ca_certificates_file =
    /etc/grid-security/certificates/INFN-CA-2006.pem<br>
    <br>
    Cheers,<br>
    <br>
        A.<br>

          is your CA certificate imported, do you 'trust' your nova
          cert? in
          <br>
          debian that would mean add it to /etc/ssl/certs

        Hi Gustavo,
        <br>
        I’ve copied my CA cert.pem in that directory (I’m running on
        CentOS 6.5), but it doesn’t seem to cure the problem.
        <br>
        I wonder if I’ve to add some particular parameter in
        /etc/nova/nova.conf, as I did for glance and other services:
        cafile, which is not documented.
        <br>

      simply copying the certificate there will not be sufficient.
      You'll need to store it under the hashed DN. That's what all the
      .0 files are there for. This short howto may help you achieve
      this:
