Configuring 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.
• 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.
• 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
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.
• 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.
• 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 expiry time and provides a choice
for the user to change the password. If the user provides a new password that is qualified, the
system records the new password and the time. If the user chooses to leave the password or the
user fails to change it, the system allows the user to log in using the present password.
NOTE:
Telnet, SSH, and terminal users can change their passwords by themselves. FTP users, on the contrary, can
only have their passwords changed by the administrator.
