+#   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
