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 user_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. attributes: check_mode: support: full diff_mode: support: full options: state: description: - State of the user_rolemapping. - On C(present), the user_rolemapping will be created if it does not yet exist, or updated with the parameters you provide. - On C(absent), the user_rolemapping will be removed if it exists. default: 'present' type: str choices: - present - absent realm: type: str description: - They Keycloak realm under which this role_representation resides. default: 'master' target_username: type: str description: - Username of the user roles are mapped to. - This parameter is not required (can be replaced by uid for less API call). uid: type: str description: - ID of the user to be mapped. - This parameter is not required for updating or deleting the rolemapping but providing it will reduce the number of API calls required. service_account_user_client_id: type: str description: - Client ID of the service-account-user to be mapped. - This parameter is not required for updating or deleting the rolemapping but providing it will reduce the number of API calls required. client_id: type: str description: - Name of the client to be mapped (different than I(cid)). - This parameter is required if I(cid) is not provided (can be replaced by I(cid) to reduce the number of API calls that must be made). cid: type: str description: - ID of the client to be mapped. - This parameter is not required for updating or deleting the rolemapping but providing it will reduce the number of API calls required. roles: description: - Roles to be mapped to the user. type: list elements: dict suboptions: name: type: str description: - Name of the role representation. - This parameter is required only when creating or updating the role_representation. id: type: str description: - The unique identifier for this role_representation. - This parameter is not required for updating or deleting a role_representation but providing it will reduce the number of API calls required. extends_documentation_fragment: - community.general.keycloak - community.general.attributes author: - Dušan Marković
