User ID, ben, is not permitted to use “123BeN321” as a password because BeN is similar
to the User ID.
• Passwords cannot contain more than four digits in succession.
When the strong password option is enabled and the password does not meet the Strong
Password requirements an error, Password characteristics do not comply with Enhance Security
requirements, is displayed.
Password Length
The length of passwords is determined by the value of the MIN_PASSWORD_LENGTH
System Flag.
• Possible flag values are between 0 and 20.
•A System Flag value of 0 means this rule is not enforced, however this rule cannot be
disabled when the Collaboration Server is in Ultra Secure Mode.
•In Ultra Secure Mode, passwords must be at least 15 characters in length (default) and
can be up to 20 characters in length.
•If the MIN_PASSWORD_LENGTH flag is enabled and the password does not meet the
required length an error, Password is too short, is displayed.
If the minimum password length is increased, valid pre-existing passwords remain valid
until users are forced to change their passwords.
Implementing Password Re-Use / History Rules
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.
