Scenario

    mod_db_passwd ommdba

  5. Enter the old password of user ommdba and enter a new password twice.

    The 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, and special characters ('~!@#$%^&*()-_=+\|[{}];:'",<.>/?).
    • The password cannot be the username or the reverse username.
    • The password cannot be the same as the last 20 historical passwords.

    If the following information is displayed, the password is changed successfully.

    Congratulations, update [ommdba] password successfully.
