Locking a User

This section describes how to lock users in MRS clusters. A locked user cannot log in to MRS Manager or perform security authentication in the cluster.

A locked user can be unlocked by a MRS cluster administrator manually or until the lock duration expires. You can lock a user by using either of the following methods:

  • Automatic lock: Set Number of Password Retries in Configure Password Policy. If user login attempts exceed the parameter value, the user is automatically locked. For details, see Modifying a Password Policy.
  • Manual lock: The MRS cluster administrator manually locks a user.

The following describes how to manually lock a user. Machine-Machine users cannot be locked.

Procedure

  1. On MRS Manager, click System.
  2. In the Permission area, click Manage User.
  3. In the row of the user to be locked, click Lock User.
  4. In the window that is displayed, click Yes to lock the user.
