   %% 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
   %% ==============
   %%

   %% The default "guest" user is only permitted to access the server
   %% via a loopback interface (e.g. localhost).

   %%                {fail_if_no_peer_cert, false}]},

   %% Choose the available SASL mechanism(s) to expose.
   %% The two default (built in) mechanisms are 'PLAIN' and
   %% 'AMQPLAIN'. Additional mechanisms can be added via
   %% plugins.
   %%
   %% See http://www.rabbitmq.com/authentication.html for more details.
   %%
   %% {auth_mechanisms, ['PLAIN', 'AMQPLAIN']},

   %% Select an authentication database to use. RabbitMQ comes bundled
   %% with a built-in auth-database, based on mnesia.
   %%
   %% {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

   %% created users. To recalculate hash for an existing user
   %% it's necessary to update her password.
   %%
   %% {password_hashing_module, rabbit_password_hashing_sha256},

   %% 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"}}]}
   %%
   %% To make the broker request the passphrase when it starts:
   %%
   %% {config_entry_decoder, [{passphrase, prompt}]}
   %%
   %% To change encryption settings:
   %%
   %% {config_entry_decoder, [{cipher,     aes_cbc256},

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

   %% On first start RabbitMQ will create a vhost and a user. These
   %% config items control what gets created. See

   %% {disk_free_limit, "50MB"},
   %% {disk_free_limit, "50000kB"},
