Switch to command:argv to avoid shell quoting and argument splitting issues. Pass -s config values as JSON arrays via to_json, fixing previous errors: Cannot parse the JSON / failed at splitting arguments. Also reconcile config.connectionUrl from ldap.server.uri. Source desired values strictly from ldap.* (no computed defaults) and assert their presence. Keep operation idempotent by reading current values and updating only on change. Minor refactor: build reusable kcadm_argv_base and expand client state extraction.
