Keystone example usage for keystone auth flags has wrong keyword arguments (flag-like). Keystone accepts token and endpoint on the command line. Valid arguments are --os-token and --os-endpoint. --token should be --os-token --endpoint should be --os-endpoint Also, updating env. varabiles from SERVICE_TOKEN to OS_SERVICE_TOKEN and SERVICE_ENDPOINT to OS_SERVICE_ENDPOINT Change-Id: I24b41c5d7ddfdd7f8a388eb7b7ba1a1b7fa59542 Closes-bug: #1307302

<para>The OpenStack Identity Service, code-named Keystone, is the
|
|
default identity management system for OpenStack. After you
|
|
install the Identity Service, you configure it through the
|
|
<filename>etc/keystone.conf</filename> configuration file and,
|
|
possibly, a separate logging configuration file. You initialize
|
|
data into the Identity Service by using the
|
|
<command>keystone</command> command-line client.</para>

<title>User CRUD</title>
|
|
<para>The Identity Service provides a user CRUD filter that can
|
|
be added to the public_api pipeline. This user CRUD filter
|
|
enables users to use a HTTP PATCH to change their own password.
|
|
To enable this extension you should define a
|
|
<literal>user_crud_extension</literal> filter, insert it after
|
|
the <literal>*_body</literal> middleware and before the
|
|
<literal>public_service</literal> application in the
|
|
public_api WSGI pipeline in <filename>keystone.conf</filename>.
|
|
For example:</para>
|
|
<programlisting language="ini"><?db-font-size 75%?>[filter:user_crud_extension]
|
|
paste.filter_factory = keystone.contrib.user_crud:CrudExtension.factory
|
|
|
|
[pipeline:public_api]
|
|
pipeline = stats_monitoring url_normalize token_auth admin_token_auth xml_body json_body debug ec2_extension user_crud_extension public_service</programlisting>
|
|
<para>Each user can then change their own password with a HTTP PATCH:</para>
|
|
<screen><prompt>$</prompt> <userinput>curl -X PATCH http://localhost:5000/v2.0/OS-KSCRUD/users/<userid> -H "Content-type: application/json" \
|
|
-H "X_Auth_Token: <authtokenid>" -d '{"user": {"password": "ABCD", "original_password": "DCBA"}}'</userinput></screen>
|
|
<para>In addition to changing their password, all of the user's current
|
|
tokens are deleted (if the back-end is KVS or sql).</para>
|
|
<note><para>Only use a KVS backend for tokens when testing.</para></note>

<section xml:id="keystone-logging">
|
|
<title>Logging</title>
|
|
<para>You configure logging externally to the rest of the Identity
|
|
Service. The file specifying the logging configuration is in the
|
|
<literal>[DEFAULT]</literal> section of the
|
|
<filename>keystone.conf</filename> file under
|
|
<literal>log_config</literal>. To route logging through
|
|
syslog, set <literal>use_syslog=true</literal> option in the
|
|
<literal>[DEFAULT]</literal> section.</para>
|
|
<para>A sample logging file is available with the project in the
|
|
<filename>etc/logging.conf.sample</filename> directory. Like
|
|
other OpenStack projects, the Identity Service uses the Python
|
|
logging module, which includes extensive configuration options
|
|
that let you define the output levels and formats.</para>
|
|
<para>Review the <filename>etc/keystone.conf</filename> sample
|
|
configuration files that are distributed with the Identity
|
|
Service. For example, each server application has its own
|
|
configuration file.</para>
|
|
<para>For services that have separate paste-deploy
|
|
<filename>.ini</filename> files, you can configure
|
|
<literal>auth_token</literal> middleware in the
|
|
<literal>[keystone_authtoken]</literal> section in the main
|
|
configuration file, such as <filename>nova.conf</filename>. For
|
|
example in Compute, you can remove the middleware parameters
|

from <filename>api-paste.ini</filename>, as follows:</para>
