The externpasscheck option in voicemail.conf allows an external script to
|
|
validate passwords when a user is changing it. The script can enforce password
|
|
strength rules. This script is an example of doing so and implements a check
|
|
on password length, a password with too many identical consecutive numbers, or
|
|
a password made up of sequential digits.
