-- Prosody Configuration File
--
-- Information on configuring Prosody can be found on our
-- website at https://prosody.im/doc/configure
--
-- Tip: You can check that the syntax of this file is correct
-- when you have finished by running this command:
--     prosodyctl check config
-- If there are any errors, it will let you know what and where
-- they are, otherwise it will keep quiet.


---------- Server-wide settings ----------
-- Settings in this section apply to the whole server and are the default settings
-- for any virtual hosts

-- This is a (by default, empty) list of accounts that are admins
-- for the server. Note that you must create the accounts separately
-- (see https://prosody.im/doc/creating_accounts for info)
-- Example: admins = { "user1@example.com", "user2@example.net" }
admins = { "{{ prosody_admin }}" }

-- Enable use of libevent for better performance under high load
-- For more information see: https://prosody.im/doc/libevent
use_libevent = true;

-- Prosody will always look in its source directory for modules, but
-- this option allows you to specify additional locations where Prosody
-- will look for modules first. For community modules, see https://modules.prosody.im/
-- For a local administrator it's common to place local modifications
-- under /usr/local/ hierarchy:
plugin_paths = { "/usr/local/lib/prosody/modules" }

-- This is the list of modules Prosody will load on startup.
-- It looks for mod_modulename.lua in the plugins folder, so make sure that exists too.
-- Documentation for bundled modules can be found at: https://prosody.im/doc/modules

-- These modules are auto-loaded, but should you want
-- to disable them then uncomment them here:
modules_disabled = {
	-- "offline"; -- Store offline messages
	-- "c2s"; -- Handle client connections
	-- "s2s"; -- Handle server-to-server connections
}

-- Disable account creation by default, for security
-- For more information see https://prosody.im/doc/creating_accounts
allow_registration = false

-- Debian:
--   Do not send the server to background, either systemd or start-stop-daemon take care of that.
--
daemonize = false;

-- Debian:
--   Please, don't change this option since /run/prosody/
--   is one of the few directories Prosody is allowed to write to
--

-- These are the SSL/TLS-related settings. If you don't want
-- to use SSL/TLS, you may comment or remove this
ssl = {
	key = "/etc/prosody/certs/{{ prosody_domain }}.key";
	certificate = "/etc/prosody/certs/{{ prosody_domain }}.crt";
}

-- Force clients to use encrypted connections? This option will
-- prevent clients from authenticating unless they are using encryption.

c2s_require_encryption = true

-- Force servers to use encrypted connections? This option will
-- prevent servers from authenticating unless they are using encryption.

s2s_require_encryption = true

-- Force certificate authentication for server-to-server connections?

s2s_secure_auth = false

-- Some servers have invalid or self-signed certificates. You can list
-- remote domains here that will not be required to authenticate using
-- certificates. They will be authenticated using DNS instead, even
-- when s2s_secure_auth is enabled.

--s2s_insecure_domains = { "insecure.example" }

-- Even if you disable s2s_secure_auth, you can still require valid
-- certificates for some domains by specifying a list here.

--s2s_secure_domains = { "jabber.org" }

-- Select the authentication backend to use. The 'internal' providers
-- use Prosody's configured data storage to store the authentication data.

-- TODO This setting needs testing, old value retained as comment
--authentication = "internal_plain"
authentication = "internal_hashed"

-- Select the storage backend to use. By default Prosody uses flat files
-- in its configured data directory, but it also supports more backends
-- through modules. An "sql" backend is included by default, but requires
-- additional dependencies. See https://prosody.im/doc/storage for more info.

--storage = "sql" -- Default is "internal" (Debian: "sql" requires one of the
-- lua-dbi-sqlite3, lua-dbi-mysql or lua-dbi-postgresql packages to work)

-- For the "sql" backend, you can uncomment *one* of the below to configure:
--sql = { driver = "SQLite3", database = "prosody.sqlite" } -- Default. 'database' is the filename.
--sql = { driver = "MySQL", database = "prosody", username = "prosody", password = "secret", host = "localhost" }
--sql = { driver = "PostgreSQL", database = "prosody", username = "prosody", password = "secret", host = "localhost" }


-- Archiving configuration
-- If mod_mam is enabled, Prosody will store a copy of every message. This
-- is used to synchronize conversations between multiple clients, even if
-- they are offline. This setting controls how long Prosody will keep
-- messages in the archive before removing them.

archive_expires_after = "2w" -- Remove archived messages after 2 weeks

-- You can also configure messages to be stored in-memory only. For more
-- archiving options, see https://prosody.im/doc/modules/mod_mam

-- Logging configuration
-- For advanced logging see https://prosody.im/doc/logging
--
-- Debian:
--  Logs info and higher to /var/log
--  Logs errors to syslog also
log = {
	-- Log files (change 'info' to 'debug' for debug logs):
	info = "/var/log/prosody/prosody.log";
	error = "/var/log/prosody/prosody.err";
	-- Syslog:
	{ levels = { "error" }; to = "syslog";  };
}

-- Uncomment to enable statistics
-- For more info see https://prosody.im/doc/statistics
-- statistics = "internal"

-- Certificates
-- Every virtual host and component needs a certificate so that clients and
-- servers can securely verify its identity. Prosody will automatically load
-- certificates/keys from the directory specified here.
-- For more information, including how to use 'prosodyctl' to auto-import certificates
-- (from e.g. Let's Encrypt) see https://prosody.im/doc/certificates

-- Location of directory to find certificates in (relative to main config file):
certificates = "certs"

-- HTTPS currently only supports a single certificate, specify it here:
--https_certificate = "/etc/prosody/certs/localhost.crt"

----------- Virtual hosts -----------
-- You need to add a VirtualHost entry for each domain you wish Prosody to serve.
-- Settings under each VirtualHost entry apply *only* to that host.
-- It's customary to maintain VirtualHost entries in separate config files
-- under /etc/prosody/conf.d/ directory. Examples of such config files can
-- be found in /etc/prosody/conf.avail/ directory.

VirtualHost "{{ prosody_domain }}"

	authentication = "cyrus"
	cyrus_application_name = "xmpp"
	cyrus_service_name = "xmpp"

	-- Assign this host a certificate for TLS, otherwise it would use the one
	-- set in the global section (if any).
	-- Note that old-style SSL on port 5223 only supports one certificate, and will always
	-- use the global one.
	ssl = {
		key = "/etc/prosody/certs/{{ prosody_domain }}.key";
		certificate = "/etc/prosody/certs/{{ prosody_domain }}.crt";
	}

------ Components ------
-- You can specify components to add hosts that provide special services,
-- like multi-user conferences, and transports.
-- For more information on components, see https://prosody.im/doc/components

---Set up a MUC (multi-user chat) room server on conference.example.com:
--Component "conference.example.com" "muc"
--- Store MUC messages in an archive and allow users to access it
--modules_enabled = { "muc_mam" }

-- Set up a SOCKS5 bytestream proxy for server-proxied file transfers:
Component "proxy.{{ prosody_domain }}" "proxy65"
	proxy65_address = "{{ prosody_domain }}"
	proxy65_acl = { "{{ prosody_domain }}" }

---Set up an external component (default component port is 5347)
--
-- External components allow adding various services, such as gateways/
-- transports to other networks like ICQ, MSN and Yahoo. For more info
-- see: https://prosody.im/doc/components#adding_an_external_component
--
--Component "gateway.example.com"
--	component_secret = "password"
