	%% Network Connectivity
	%% ====================
	%%

	%% By default, RabbitMQ will listen on all interfaces, using
	%% the standard (reserved) AMQP port.
	%%
	%% {tcp_listeners, [5672]},

	%% To listen on a specific interface, provide a tuple of {IpAddress, Port}.
	%% For example, to listen only on localhost for both IPv4 and IPv6:
	%%
	%% {tcp_listeners, [{"127.0.0.1", 5672},
	%% {"::1", 5672}]},

	%% SSL listeners are configured in the same fashion as TCP listeners,
	%% including the option to control the choice of interface.
	%%
	%% {ssl_listeners, [5671]},

	%% Number of Erlang processes that will accept connections for the TCP
	%% and SSL listeners.
	%%
	%% {num_tcp_acceptors, 10},
	%% {num_ssl_acceptors, 1},

	%% Maximum time for AMQP 0-8/0-9/0-9-1 handshake (after socket connection
	%% and SSL handshake), in milliseconds.
	%%
	%% {handshake_timeout, 10000},

	%% Log levels (currently just used for connection logging).
	%% One of 'debug', 'info', 'warning', 'error' or 'none', in decreasing
	%% order of verbosity. Defaults to 'info'.
	%%
	%% {log_levels, [{connection, info}, {channel, info}]},

	%% Set to 'true' to perform reverse DNS lookups when accepting a
	%% connection. Hostnames will then be shown instead of IP addresses
	%% in rabbitmqctl and the management plugin.
	%%
	%% {reverse_dns_lookups, true},

	%%
	%% Security / AAA

	%% {auth_backends, [rabbit_auth_backend_internal]},

	%% Configurations supporting the rabbitmq_auth_mechanism_ssl and
	%% rabbitmq_auth_backend_ldap plugins.
	%%
	%% NB: These options require that the relevant plugin is enabled.
	%% See http://www.rabbitmq.com/plugins.html for further details.

	%% The RabbitMQ-auth-mechanism-ssl plugin makes it possible to
	%% authenticate a user based on the client's SSL certificate.
	%%
	%% To use auth-mechanism-ssl, add to or replace the auth_mechanisms
	%% list with the entry 'EXTERNAL'.
	%%
	%% {auth_mechanisms, ['EXTERNAL']},

	%% The rabbitmq_auth_backend_ldap plugin allows the broker to
	%% perform authentication and authorisation by deferring to an
	%% external LDAP server.
	%%
	%% For more information about configuring the LDAP backend, see
	%% http://www.rabbitmq.com/ldap.html.
	%%
	%% Enable the LDAP auth backend by adding to or replacing the
	%% auth_backends entry:
	%%
	%% {auth_backends, [rabbit_auth_backend_ldap]},

	%% This pertains to both the rabbitmq_auth_mechanism_ssl plugin and
	%% STOMP ssl_cert_login configurations. See the rabbitmq_stomp
	%% configuration section later in this file and the README in
	%% https://github.com/rabbitmq/rabbitmq-auth-mechanism-ssl for further

	%% Configuration entry encryption.
	%% See http://www.rabbitmq.com/configure.html#configuration-encryption
	%%
	%% To specify the passphrase in the configuration file:
	%%
	%% {config_entry_decoder, [{passphrase, <<"mypassphrase">>}]}
	%%
	%% To specify the passphrase in an external file:
	%%
	%% {config_entry_decoder, [{passphrase, {file, "/path/to/passphrase/file"}}]}

	%% Default User / VHost
	%% ====================
