Scenario

Periodically change the passwords of LDAP administrator rootdn:cn=root,dc=hadoop,dc=com and LDAP user pg_search_dn:cn=pg_search_dn,ou=Users,dc=hadoop,dc=com to improve the system O&M security.

All services need to be restarted for the new password to take effect. The services are unavailable during the restart.

  3. In the Change Password dialog box, select the user whose password to be modified in the User Information drop-down box.
  4. Enter the old password in the Old Password text box, and enter the new password in the New Password and Confirm Password text boxes.

    The default password complexity requirements are as follows:

    • The password contains 16 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.
    • The new password cannot be the same as the current password.
