Polycom, Inc. 23-23
Defining Password Aging
The duration of password validity is determined by the value of the
PASSWORD_EXPIRATION_DAYS System Flag.
• Passwords can be set to be valid for durations of between 0 and 90 days.
•If the System Flag is set to 0, user passwords do not expire. The System Flag cannot be set
to 0 when the Collaboration Server is in Ultra Secure Mode.
•In Ultra Secure Mode, the minimum duration can be set to 7 days and the default
duration is 60 days.
The display of a warning to the user of the number of days until password expiration is
determined by the value of the PASSWORD_EXPIRATION_WARNING_DAYS System
Flag.
• Possible number of days to display expiry warnings is between 0 and 14.
•If the System Flag is set to 0, password expiry warnings are not displayed. The System
Flag cannot be set to 0 when the Collaboration Server is in Ultra Secure Mode.
•In Ultra Secure Mode, the earliest warning can be displayed 14 days before passwords
are due to expire and the latest warning can be displayed 7 days before passwords are
due to expire (default setting).
• If a user attempts to log in after his/her password has expired, an error is displayed:
User must change password.
Maximum Repeating Characters
There are two separate flags that control the maximum number of repeated characters
permitted in a password, one for the user password and one for the chairperson
(conference) password.
• MAX_PASSWORD_REPEATED_CHAR allows the administrator to configure the
maximum number of consecutive repeating characters to be allowed in a user
password.
Range: 1 - 4
Default: 2
• MAX_CONF_PASSWORD_REPEATED_DIGITS allows the administrator to configure
the maximum number of consecutive re
peating digit
s to be allowed in a conference
password.
Range: 1 - 4
Default: 2
Defining Password Change Frequency
The frequency with which a user can change a password is determined by the value of the
MIN_PWD_CHANGE_FREQUENCY_IN_DAYS System Flag. The value of the flag is the
number of days that users must retain a password.
• Possible retention period is between 0 and 7 days. In Ultra Secure Mode the retention
period is between 1 (default) and 7.
•If the System Flag is set to 0, users do not have to change their passwords. The System
Flag cannot be set to 0 when the Collaboration Server is in Ultra Secure Mode.
• If a user attempts to change a password within the time period specified by this flag, an
error, Password change is not allowed before defined min time has passed, is displayed.
An administrator can assign a new password to a user at any time.
