module: keycloak_client_rolemapping
|
||||
|
||||
short_description: Allows administration of Keycloak client_rolemapping with the Keycloak API
|
||||
version_added: 3.5.0
|
||||
|
||||
description:
|
||||
- This module allows you to add, remove or modify Keycloak client_rolemapping with the Keycloak REST API.
|
||||
It requires access to the REST API via OpenID Connect; the user connecting and the client 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 client 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 ones found in the
|
||||
Keycloak API and its documentation at U(https://www.keycloak.org/docs-api/8.0/rest-api/index.html).
|
||||
|
||||
- Attributes are multi-valued in the Keycloak API. All attributes are lists of individual values and will
|
||||
be returned that way by this module. You may pass single values for attributes when calling the module,
|
||||
and this will be translated into a list suitable for the API.
|
||||
|
||||
- When updating a client_rolemapping, where possible provide the role ID to the module. This removes a lookup
|
||||
to the API to translate the name into the role ID.
|
||||

||||
|
||||
