Configure the Identity service with SSL

You can configure the Identity service to support two-way SSL.

You must obtain the x509 certificates externally and configure them.

The Identity service provides a set of sample certificates in the examples/pki/certs and examples/pki/private directories:

cacert.pem

Certificate Authority chain to validate against.

ssl_cert.pem

Public certificate for Identity service server.

middleware.pem

Public and private certificate for Identity service middleware/client.

cakey.pem

Private key for the CA.

ssl_key.pem

Private key for the Identity service server.

Note

You can choose names for these certificates. You can also combine public/private keys in the same file, if you wish. These certificates are provided as an example.

Client authentication with keystone-all

When running keystone-all, the server can be configured to enable SSL with client authentication using the following instructions. Modify the [eventlet_server_ssl] section in the /etc/keystone/keystone.conf file. The following SSL configuration example uses the included sample certificates:

[eventlet_server_ssl]
enable = True
certfile = <path to keystone.pem>
keyfile = <path to keystonekey.pem>
ca_certs = <path to ca.pem>
cert_required = True

Options

• enable

  True enables SSL. Default is False.

• certfile

  Path to the Identity service public certificate file.

• keyfile

  Path to the Identity service private certificate file. If you include the private key in the certfile, you can omit the keyfile.

• ca_certs

  Path to the CA trust chain.

• cert_required

  Requires client certificate. Default is False.

When running the Identity service as a WSGI service in a web server such as Apache httpd, this configuration is done in the web server instead. In this case the options in the [eventlet_server_ssl] section are ignored.
