Custom Javascript policies are only available if a client has Authorization enabled and if they have been deployed to the Keycloak server as JAR files. - This module requires access to the REST API via OpenID Connect; the user connecting and the realm being used must have the requisite access rights. In a default Keycloak installation, admin-cli and an admin user would work, as would a separate realm definition with the scope tailored to your needs and a user having the expected roles. - The names of module options are snake_cased versions of the camelCase options used by Keycloak. The Authorization Services paths and payloads have not officially been documented by the Keycloak project.
