# 1. Attempt to access a key ZNode via zkCli as an unauthorized identity (should be denied) zkCli.sh -server <zk_ip>:<port> ls /tdsql # Expected: Authentication is not valid # 2. Compare the deployed ZK authentication credentials against the install template's initial values; they must differ # (The exact location depends on the deployment form: centralized deployment uses scheduler.xml; TCE deployment uses the tdsql_install template)

Re-setAcl existing ZNodes to apply the new credentials. 4. Enable ACL mode (see Recommendation 10.1). Note: This operation requires updating all components simultaneously;
