In addition to notifying Macintosh client users that their password is expiring at initial login, ExtremeZ-IP can also be configured to notify users during their session. Notification during a session requires that notification at initial login is enabled. To do this, select the Notify Mac clients of password expiration option on the Security tab of the Settings dialog in the ExtremeZ-IP Administrator. Here, you will also specify the number of days from expiration that the notification should begin.
Next, you will edit the registry key named PasswordExpirationReminderInterval in:
...\Parameters4\Refreshable\
The value of this registry key determines the interval at which the client is notified of the upcoming password expiration in minutes.The interval can be configured from 1 minute to 1440 minutes (1 day).
