 | |
|         #
 | |
|         #   idp_icon: An optional icon for this identity provider, which is presented

 | |
|         #       MXC URI of the format mxc://<server-name>/<media-id>. (An easy way to

|         #
 | |

|         #      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.

|         #          jwt_header: a dictionary giving properties to include in the JWT

 | |
|         #
 | |

 | |
|         #   scopes: list of scopes to request. This should normally include the "openid"

|         #
 | |
|         #   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.
 | |
|         #

 | |
|         #
 | |
|         #       Defaults to 'auto', which uses the userinfo endpoint if 'openid' is

 | |
|         #       userinfo endpoint.
 | |
|         #
 | |
|         #   allow_existing_users: set to 'true' to allow a user logging in via OIDC to

 | |
|         #       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

 | |
|         #
 | |
|         #       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
