Changing the Password of an Operation User

Updated at: Aug 17, 2021 GMT+08:00

Scenario

Passwords of Human-machine system users must be regularly changed to ensure MRS cluster security. This section describes how to change passwords on MRS Manager.

If a new password policy needs to be used for the password modified by the user, follow instructions in Modifying a Password Policy to modify the password policy and then perform the following operations to modify the password.

The operations described in this section apply only to clusters of versions earlier than MRS 3.x.

For clusters of MRS 3.x or later, see Changing a User Password.

Impact on the System

If you have downloaded a user authentication file, download it again and obtain the keytab file after modifying the password of the MRS cluster user.

Prerequisites

  • You have obtained the current password policies from the administrator.
  • You have obtained the MRS Manager access address from the administrator.
  • You have obtained a cluster with Kerberos authentication enabled or a common cluster with the EIP function enabled.

Procedure

  1. Access MRS Manager. For details, see Accessing Manager.
  2. On MRS Manager, move the mouse cursor to in the upper right corner.

    On the menu that is displayed, select Change Password.

  3. Fill in the Old Password, New Password, and Confirm Password. Click OK.

    For the cluster, the default password complexity requirements are as follows:
    • The password must contain 8 to 32 characters.
    • The password must contain at least three types of the following: uppercase letters, lowercase letters, digits, spaces, and special characters ('~!@#$%^&*()-_=+\|[{}];:'",<.>/?).
    • The password cannot be the username or the reverse username.
