+   %% 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.

+
+   %% Choose the available SASL mechanism(s) to expose.
+   %% The two default (built in) mechanisms are 'PLAIN' and

+   %% 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

+   %%
+   %% For more information about configuring the LDAP backend, see

+   %%
+   %% Enable the LDAP auth backend by adding to or replacing the

+   %% 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:

+   %% ==============

+
+   %% Pattern to convert the username given through AMQP to a DN before
+   %% binding
+   %%
+   %% {user_dn_pattern, "cn=${username},ou=People,dc=example,dc=com"},
+
+   %% Alternatively, you can convert a username to a Distinguished
+   %% Name via an LDAP lookup after binding. See the documentation for
+   %% full details.
+
+   %% When converting a username to a dn via a lookup, set these to
+   %% the name of the attribute that represents the user name, and the
+   %% base DN for the lookup query.
+   %%
+   %% {dn_lookup_attribute,   "userPrincipalName"},
+   %% {dn_lookup_base,        "DC=gopivotal,DC=com"},
+
+   %% Controls how to bind for authorisation queries and also to
+   %% retrieve the details of users logging in without presenting a
+   %% password (e.g., SASL EXTERNAL).
+   %% One of
+   %%  - as_user (to bind as the authenticated user - requires a password)
+   %%  - anon    (to bind anonymously)
+   %%  - {UserDN, Password} (to bind with a specified user name and password)
+   %%
+   %% Defaults to 'as_user'.

+   %%
+   %% Authorisation
+   %% =============
+   %%
+
+   %% The LDAP plugin can perform a variety of queries against your
+   %% LDAP server to determine questions of authorisation. See
+   %% http://www.rabbitmq.com/ldap.html#authorisation for more
+   %% information.
+
+   %% Set the query to use when determining vhost access
+   %%
+   %% {vhost_access_query, {in_group,
+   %%                       "ou=${vhost}-users,ou=vhosts,dc=example,dc=com"}},
+
+   %% Set the query to use when determining resource (e.g., queue) access
+   %%
+   %% {resource_access_query, {constant, true}},
+
+   %% Set queries to determine which tags a user has
+   %%
+   %% {tag_queries, []}
