Locking an MRS Cluster User

A user may be suspended for a long period of time due to service changes. For security purposes, you can lock such a user. You can lock a user in using either of the following methods:

  • Automatic locking: You can set Password Retries in the password policy to automatically lock the user whose login attempts exceed this parameter value. For details, see Configuring Password Policies for MRS Cluster Users.
  • Manual locking: You manually lock a user.

This section describes how to lock a user manually. Machine-machine users cannot be locked. For details about how to unlock an MRS cluster user, see Unlocking a User Created on Manager.

Impact on the System

A locked user cannot log in to Manager or perform identity authentication in the cluster. A locked user can be used only after being manually unlocked or the lock time expires.
