The Renew automatically at check box determines whether or not renewable tickets will be renewed by NetIdMgr when they reach the specified time remaining.
By default the Renew at half life intervals when possible option is enabled. When enabled, Network Identity Manager will trigger a renewal attempt for an identity when its remaining lifetime reaches a half of its original lifetime. If the renewal is unsuccessful, another attempt will be made to renew the identity after another one half of the remaining lifetime has elapsed. This process continues until the identity is successfully renews or the remaining lifetime is too short for a renewal attempt.
The Initial warning at check box determines whether or not a warning will be issued when the specified time remaining is reached.
The Final warning at check box determines whether or not a warning will be issued when the specified time remaining is reached.
Notifications are performed in two ways. First, icons are displayed next to the affected credentials in the flags column of the display. Second, a balloon tip is displayed off of the NetIdMgr taskbar notification area icon.
