Password control overview
Password control refers to a set of functions provided by the local authentication server to control user
login passwords, super passwords, and user login status based on predefined policies. The rest of this
section describes the password control functions in detail.
1. Minimum password length
By setting a minimum password length, you can enforce users to use passwords long enough for system
security. If a user specifies a shorter password, the system rejects the setting and prompts the user to
re-specify a password.
2. Minimum password update interval
This function allows you to set the minimum interval at which users can change their passwords. If a
non-manage level user logs in to change the password but the time that elapses since the last change is
less than this interval, the system denies the request. For example, if you set this interval to 48 hours, a
non-manage level user cannot change the password twice within 48 hours. This prevents users from
changing their passwords frequently.
NOTE:
This function is not effective for users of the manage level. For information about user levels, see the
•
Fundamentals Configuration Guide
This function is not effective for a user who is prompted to change the password at the first login or a user
•
whose password has just been aged out.
3. Password aging
Password aging imposes a lifecycle on a user password. After the password aging time expires, the user
needs to change the password.
If a user enters an expired password when logging in, the system displays an error message and prompts
the user to provide a new password and to confirm it by entering it again. The new password must be a
valid one and the user must enter exactly the same password when confirming it.
4. Early notice on pending password expiration
When a user logs in, the system checks whether the password will expire in a time equal to or less than
the specified period. If so, the system notifies the user of the expiration time and provides a choice for the
user to change the password. If the user provides a new that is complexity-compliant, the system records
