return """\
# List of OpenID Connect (OIDC) / OAuth 2.0 identity providers, for registration
# and login.
#
# Options for each entry include:
#
# idp_id: a unique identifier for this identity provider. Used internally
# by Synapse; should be a single word such as 'github'.
#
# Note that, if this is changed, users authenticating via that provider
# will no longer be recognised as the same user!
#
# (Use "oidc" here if you are migrating from an old "oidc_config"
# configuration.)
#
# idp_name: A user-facing name for this identity provider, which is used to
# offer the user a choice of login mechanisms.
#
# idp_icon: An optional icon for this identity provider, which is presented
# by clients and Synapse's own IdP picker page. If given, must be an
# MXC URI of the format mxc://<server-name>/<media-id>. (An easy way to
# obtain such an MXC URI is to upload an image to an (unencrypted) room
# and then copy the "url" from the source of the event.)
#
# idp_brand: An optional brand for this identity provider, allowing clients
# to style the login flow according to the identity provider in question.
# See the spec for possible options here.
#
# discover: set to 'false' to disable the use of the OIDC discovery mechanism
# to discover endpoints. Defaults to true.
#
# issuer: Required. The OIDC issuer. Used to validate tokens and (if discovery
# is enabled) to discover the provider's endpoints.
#
# client_id: Required. oauth2 client id to use.
#
# client_secret: oauth2 client secret to use. May be omitted if
# client_secret_jwt_key is given, or if client_auth_method is 'none'.
#
# client_secret_jwt_key: Alternative to client_secret: details of a key used
# to create a JSON Web Token to be used as an OAuth2 client secret. If
# given, must be a dictionary with the following properties:
#
# key: a pem-encoded signing key. Must be a suitable key for the
# algorithm specified. Required unless 'key_file' is given.
#
# key_file: the path to file containing a pem-encoded signing key file.
# Required unless 'key' is given.
#
# jwt_header: a dictionary giving properties to include in the JWT
# header. Must include the key 'alg', giving the algorithm used to
# sign the JWT, such as "ES256", using the JWA identifiers in
# RFC7518.
#
# jwt_payload: an optional dictionary giving properties to include in
# the JWT payload. Normally this should include an 'iss' key.
#
# client_auth_method: auth method to use when exchanging the token. Valid
# values are 'client_secret_basic' (default), 'client_secret_post' and
# 'none'.
#
# scopes: list of scopes to request. This should normally include the "openid"
# scope. Defaults to ["openid"].
#
# authorization_endpoint: the oauth2 authorization endpoint. Required if
# provider discovery is disabled.
#
# token_endpoint: the oauth2 token endpoint. Required if provider discovery is
# disabled.
#
# userinfo_endpoint: the OIDC userinfo endpoint. Required if discovery is
# disabled and the 'openid' scope is not requested.
#
# jwks_uri: URI where to fetch the JWKS. Required if discovery is disabled and
# the 'openid' scope is used.
#
# skip_verification: set to 'true' to skip metadata verification. Use this if
# you are connecting to a provider that is not OpenID Connect compliant.
# Defaults to false. Avoid this in production.
#
# user_profile_method: Whether to fetch the user profile from the userinfo
# endpoint, or to rely on the data returned in the id_token from the
# token_endpoint.
#
# Valid values are: 'auto' or 'userinfo_endpoint'.
#
# Defaults to 'auto', which uses the userinfo endpoint if 'openid' is
# not included in 'scopes'. Set to 'userinfo_endpoint' to always use the
# userinfo endpoint.
#
# allow_existing_users: set to 'true' to allow a user logging in via OIDC to
# match a pre-existing account instead of failing. This could be used if
# switching from password logins to OIDC. Defaults to false.
#
# user_mapping_provider: Configuration for how attributes returned from a OIDC
# provider are mapped onto a matrix user. This setting has the following
# sub-properties:
#
# module: The class name of a custom mapping module. Default is
# {mapping_provider!r}.
# See https://matrix-org.github.io/synapse/latest/sso_mapping_providers.html#openid-mapping-providers
# for information on implementing a custom mapping provider.
#
# config: Configuration for the mapping provider module. This section will
# be passed as a Python dictionary to the user mapping provider
# module's `parse_config` method.
#
# For the default provider, the following settings are available:
#
# subject_claim: name of the claim containing a unique identifier
# for the user. Defaults to 'sub', which OpenID Connect
# compliant providers should provide.
#
# localpart_template: Jinja2 template for the localpart of the MXID.
# If this is not set, the user will be prompted to choose their
# own username (see the documentation for the
# 'sso_auth_account_details.html' template). This template can
# use the 'localpart_from_email' filter.
#
# confirm_localpart: Whether to prompt the user to validate (or
# change) the generated localpart (see the documentation for the
# 'sso_auth_account_details.html' template), instead of
# registering the account right away.
#
# display_name_template: Jinja2 template for the display name to set
# on first login. If unset, no displayname will be set.
#
# email_template: Jinja2 template for the email address of the user.
# If unset, no email address will be added to the account.
#
# extra_attributes: a map of Jinja2 templates for extra attributes
# to send back to the client during login.
# Note that these are non-standard and clients will ignore them
# without modifications.
#
# When rendering, the Jinja2 templates are given a 'user' variable,
# which is set to the claims returned by the UserInfo Endpoint and/or
# in the ID Token.
#
# It is possible to configure Synapse to only allow logins if certain attributes
# match particular values in the OIDC userinfo. The requirements can be listed under
# `attribute_requirements` as shown below. All of the listed attributes must
# match for the login to be permitted. Additional attributes can be added to
# userinfo by expanding the `scopes` section of the OIDC config to retrieve
# additional information from the OIDC provider.
#
# If the OIDC claim is a list, then the attribute must match any value in the list.
# Otherwise, it must exactly match the value of the claim. Using the example
# below, the `family_name` claim MUST be "Stephensson", but the `groups`
# claim MUST contain "admin".
#
# attribute_requirements:
# - attribute: family_name
# value: "Stephensson"
# - attribute: groups
# value: "admin"
#
# See https://matrix-org.github.io/synapse/latest/openid.html
# for information on how to configure these options.
#
# For backwards compatibility, it is also possible to configure a single OIDC
# provider via an 'oidc_config' setting. This is now deprecated and admins are
# advised to migrate to the 'oidc_providers' format. (When doing that migration,
# use 'oidc' for the idp_id to ensure that existing users continue to be
# recognised.)
