#       one of the given keys.
#
#    accept_keys_insecurely: a boolean. Normally, if `verify_keys` is unset,
#       and federation_verify_certificates is not `true`, synapse will refuse
#       to start, because this would allow anyone who can spoof DNS responses
#       to masquerade as the trusted key server. If you know what you are doing
#       and are sure that your network environment provides a secure connection
#       to the key server, you can set this to `true` to override this
#       behaviour.
#
# An example configuration might look like:
#
#trusted_key_servers:
#  - server_name: "my_trusted_server.example.com"
#    verify_keys:
#      "ed25519:auto": "abcdefghijklmnopqrstuvwxyzabcdefghijklmopqr"
#  - server_name: "my_other_trusted_server.example.com"
#
# The default configuration is:
#
#trusted_key_servers:
#  - server_name: "matrix.org"


# Enable SAML2 for registration and login. Uses pysaml2.
#
# `sp_config` is the configuration for the pysaml2 Service Provider.
# See pysaml2 docs for format of config.
#
# Default values will be used for the 'entityid' and 'service' settings,
# so it is not normally necessary to specify them unless you need to
# override them.
#
# Once SAML support is enabled, a metadata file will be exposed at
# https://<server>:<port>/_matrix/saml2/metadata.xml, which you may be able to
# use to configure your SAML IdP with. Alternatively, you can manually configure
# the IdP to use an ACS location of
# https://<server>:<port>/_matrix/saml2/authn_response.
#
#saml2_config:
#  sp_config:
#    # point this to the IdP's metadata. You can use either a local file or
#    # (preferably) a URL.
#    metadata:
#      #local: ["saml2/idp.xml"]
#      remote:
#        - url: https://our_idp/metadata.xml
#
#    # By default, the user has to go to our login page first. If you'd like to
#    # allow IdP-initiated login, set 'allow_unsolicited: True' in a
#    # 'service.sp' section:
#    #
#    #service:
#    #  sp:
#    #    allow_unsolicited: True
#
#    # The examples below are just used to generate our metadata xml, and you
#    # may well not need it, depending on your setup. Alternatively you
#    # may need a whole lot more detail - see the pysaml2 docs!

# User Directory configuration
#
# 'enabled' defines whether users can search the user directory. If
# false then empty responses are returned to all queries. Defaults to
# true.
#
# 'search_all_users' defines whether to search all users visible to your HS
# when searching the user directory, rather than limiting to users visible

# User Consent configuration
#
# for detailed instructions, see
# https://github.com/matrix-org/synapse/blob/master/docs/consent_tracking.md
#
# Parts of this section are required if enabling the 'consent' resource under
# 'listeners', in particular 'template_dir' and 'version'.
#
# 'template_dir' gives the location of the templates for the HTML forms.
# This directory should contain one subdirectory per language (eg, 'en', 'fr'),
# and each language directory should contain the policy document (named as
# '<version>.html') and a success page (success.html).
#
# 'version' specifies the 'current' version of the policy document. It defines
# the version to be served by the consent resource if there is no 'v'
# parameter.
#
# 'server_notice_content', if enabled, will send a user a "Server Notice"
# asking them to consent to the privacy policy. The 'server_notices' section
# must also be configured for this to work. Notices will *not* be sent to
# guest users unless 'send_server_notice_to_guests' is set to true.
#
# 'block_events_error', if set, will block any attempts to send events
# until the user consents to the privacy policy. The value of the setting is
# used as the text of the error.
#
# 'require_at_registration', if enabled, will add a step to the registration
# process, similar to how captcha works. Users will be required to accept the
# policy before their account is created.
#
# 'policy_name' is the display name of the policy users will see when registering
# for an account. Has no effect unless `require_at_registration` is enabled.
# Defaults to "Privacy Policy".
#
#user_consent:
#  template_dir: res/templates/privacy

# Server Notices room configuration
#
# Uncomment this section to enable a room which can be used to send notices
# from the server to users. It is a special room which cannot be left; notices
# come from a special "notices" user id.
#
# If you uncomment this section, you *must* define the system_mxid_localpart
# setting, which defines the id of the user which will be used to send the
# notices.
#
# It's also possible to override the room name, the display name of the
# "notices" user, and the avatar for the user.
#
#server_notices:
#  system_mxid_localpart: notices
#  system_mxid_display_name: "Server Notices"
#  system_mxid_avatar_url: "mxc://server.com/oumMVlgDnLYFaPVkExemNVVZ"

# The `alias_creation` option controls who's allowed to create aliases
# on this server.
#
# The format of this option is a list of rules that contain globs that
# match against user_id, room_id and the new alias (fully qualified with
# server name). The action in the first rule that matches is taken,
# which can currently either be "allow" or "deny".
#
# Missing user_id/room_id/alias fields default to "*".
#
# If no rules match the request is denied. An empty list means no one
# can create aliases.
#
# Options for the rules include:
#
#   user_id: Matches against the creator of the alias
#   alias: Matches against the alias being created
#   room_id: Matches against the room ID the alias is being pointed at
#   action: Whether to "allow" or "deny" the request if the rule matches
#
# The default is:
#
#alias_creation_rules:
#  - user_id: "*"
#    alias: "*"
#    room_id: "*"
#    action: allow

# The `room_list_publication_rules` option controls who can publish and
# which rooms can be published in the public room list.
#
# The format of this option is the same as that for
# `alias_creation_rules`.
#
# If the room has one or more aliases associated with it, only one of
# the aliases needs to match the alias rule. If there are no aliases
# then only rules with `alias: *` match.
#
# If no rules match the request is denied. An empty list means no one
# can publish rooms.
#
# Options for the rules include:
#
#   user_id: Matches agaisnt the creator of the alias
#   room_id: Matches against the room ID being published
#   alias: Matches against any current local or canonical aliases
#            associated with the room
#   action: Whether to "allow" or "deny" the request if the rule matches
#
# The default is:
#
#room_list_publication_rules:
#  - user_id: "*"
#    alias: "*"
#    room_id: "*"
#    action: allow


# Server admins can define a Python module that implements extra rules for
# allowing or denying incoming events. In order to work, this module needs to
# override the methods defined in synapse/events/third_party_rules.py.

# participating server enforces the same rules.

## Opentracing ##

# These settings enable opentracing, which implements distributed tracing.
# This allows you to observe the causal chains of events across servers
# including requests, key lookups etc., across any server running
# synapse or any other other services which supports opentracing
# (specifically those implemented with Jaeger).
#

    # tracing is disabled by default. Uncomment the following line to enable it.
