RealPresence Collaboration Server (RMX) 1500/1800/2000/4000 Administrator’s Guide

Users are prevented from re-using previous passwords by keeping a list of previous passwords. If a 
password is recorded in the list, it cannot be re-used. The list is cyclic, with the most recently recorded 
password causing the deletion of the oldest recorded password.

● The number of passwords that are recorded is determined by the value of the 

PASSWORD_HISTORY_SIZE System Flag. Possible values are between 0 and 16.

● A flag value of 0 means the rule is not enforced, however this rule cannot be disabled when the 

Collaboration Server is in Ultra Secure Mode.

● In Ultra Secure Mode, at least 10 passwords (default) and up to 16 passwords must be retained.

If the password does not meet this requirement, an error, New password was used recently, is displayed.

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.

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 repeating digits to be allowed in a conference password.
Range: 1 - 4
Default: 2
