"permissive" (default) to validate binding information if the bind type is of a form known to the server and ignore it if not. "strict" like "permissive" but if the bind type is unknown the token will be rejected. "required" any form of token binding is needed to be allowed. Finally the name of a binding method that must be present in tokens.</td>

The hashes will be tried in the order given, so put the preferred one first for performance. The result of the first hash will be stored in the cache. This will typically be set to multiple values only while migrating from a less secure algorithm to a more secure one.

<title>Introduction to the Messaging and Notifications service</title>
<para>Zaqar is a multi-tenant, fast, reliable, scalable cloud messaging and notification service.
It allows developers to share data between distributed application components performing different tasks,
without losing messages or requiring each component to be always available.</para>
<para>The service features a ReST API, which developers can use to send messages between various
components of their SaaS and mobile applications, by using a variety of communication patterns.</para>
<para>Underlying this API is an efficient messaging engine designed with scalability and security in mind.</para>
<simplesect>
<title>Key features</title>
<para>The Messaging and Notifications service provides the following key features:</para>
<itemizedlist>
<listitem>
<para>Firewall-friendly, HTTP-based API with Keystone support</para>
</listitem>
<listitem>
<para>Multi-tenant queues based on Keystone project IDs</para>
</listitem>
<listitem>
<para>Support for several common patterns including event broadcasting, task distribution, and point-to-point messaging</para>
</listitem>
<listitem>
<para>Component-based architecture with support for custom backends and message filters</para>
</listitem>
<listitem>
<para>Efficient reference implementation with an eye toward low latency and high throughput (dependent on backend)</para>
</listitem>
<listitem>
<para>Highly-available and horizontally scalable</para>

<title>Components</title>
<para>The Messaging and Notifications service contains the following components:</para>
<itemizedlist>
<listitem>
<para><emphasis role="bold">Transport backend</emphasis>. The Messaging and Notifications
service requires the selection of a transport specification responsible of the communication
between the endpoints. In addition to the base driver implementation, the Messaging
and Notifications service also provides the means to add support for other transport mechanisms.
The default option is WSGI.
</para>
</listitem>
<listitem>
<para><emphasis role="bold">Storage backend</emphasis>. The Messaging and Notifications service
depends on a storage engine for message persistence. In addition to the base driver implementation,
the Messaging and Notifications service also provides the means to add support for other
storage solutions. The default storage option is MongoDB.
</para>

<chapter xml:id="configuration">
<title>Configure the Messaging and Notifications service</title>
<section xml:id="configuration-overview">
<title>Overview of zaqar.conf</title>
<para>The <filename>zaqar.conf</filename>
configuration file uses an <link xlink:href="https://en.wikipedia.org/wiki/INI_file">INI file format</link>
as explained in the
<link xlink:href="http://docs.openstack.org/trunk/config-reference/content/config_format.html">"Configuration file format"</link>
section of the <link xlink:href="http://docs.openstack.org/trunk/config-reference">OpenStack Configuration Reference</link>.
</para>
<para>This file is located in <literal>/etc/zaqar</literal> within the Zaqar folder.
When you manually install the Messaging and Notifications service,
you must generate the zaqar.conf file using the config samples
generator located in <literal>tools/config/generate_sample.sh</literal>
and customize it according to your preferences.</para>
<para>Example usage of the sample generator script:
<programlisting>
$ generate_sample.sh -b /opt/stack/zaqar -p zaqar -o /etc/zaqar
</programlisting>
</para>

<title>Sections</title>
<para>Configuration options are grouped by section. The
Message Queueing configuration file supports the following sections:
<variablelist>
<varlistentry>

<section xml:id="config-api">
<title>API options</title>
<para>The Messaging and Notifications service can be configured by changing the following
parameters:
</para>
<xi:include href="common/tables/zaqar-api.xml"/>
</section>
<section xml:id="config-logging">
<title>Configure logging</title>
<para>You can use the zaqar.conf file to configure where the Messaging and Notifications service logs events,
the logging levels and log formats.</para>
<para>To customize logging for the Messaging and Notifications service, use the following configuration
settings in the [DEFAULT] section:</para>
<xi:include href="common/tables/zaqar-logging.xml"/>
</section>
<section xml:id="config-drivers">
<title>Configure drivers</title>
<para>The transport and storage drivers used by the Messaging and Notifications service
are determined by the following options:</para>
<xi:include href="common/tables/zaqar-drivers.xml"/>
</section>
<section xml:id="config-storage">
<title>Configure general storage driver options</title>
<para>The Messaging and Notifications service supports several different backends for storing
messages and their metadata. The recommended storage backend is MongoDB.
The following tables detail the available options:</para>
<xi:include href="common/tables/zaqar-storage.xml"/>
<xi:include href="common/tables/zaqar-mongodb.xml"/>
</section>
<section xml:id="config-transport">
<title>Configure general transport driver options</title>
<para>The Messaging and Notifications service uses WSGI as the default transport mechanism.
The following tables detail the available options:</para>
<xi:include href="common/tables/zaqar-transport.xml"/>
<xi:include href="common/tables/zaqar-wsgi.xml"/>
</section>
<section xml:id="config-auth">
<title>Configure authentication and authorization</title>
<para>All requests to the API may only be performed by an authenticated agent.</para>
<para>The preferred authentication system is the OpenStack Identity service, code-named Keystone.</para>
<para>To authenticate, an agent issues an authentication request to a Keystone Identity Service endpoint.
In response to valid credentials, Keystone responds with an auth token and a service catalog that
contains a list of all services and endpoints available for the given token.</para>
<para>Multiple endpoints may be returned for Zaqar according to physical locations
and performance/availability characteristics of different deployments.</para>
<para>Normally, Keystone middleware provides the <literal>X-Project-Id</literal> header based on the
auth token submitted by the Zaqar client.</para>
<para>For this to work, clients must specify a valid auth token in the <literal>X-Auth-Token</literal>
header for each request to the Zaqar API. The API validates auth tokens against Keystone before
servicing each request</para>
<para>If auth is not enabled, clients must provide the <literal>X-Project-Id</literal> header themselves.</para>
<para>Configure the authentication and authorization strategy through these options:</para>
<xi:include href="common/tables/zaqar-authentication.xml"/>
<xi:include href="common/tables/zaqar-auth_token.xml"/>
</section>
<section xml:id="config-pooling">
<title>Configure pooling</title>
<para>The Messaging and Notifications service supports pooling.</para>
<para>
Pooling aims to make Zaqar highly scalable without losing any of its flexibility
by allowing users to use multiple-backends.
</para>
<para>You can enable and configure pooling with the following options:</para>
<xi:include href="common/tables/zaqar-pooling.xml"/>
