KFW does not cache the user's password. If the KDC is not reachable
during logon, the user will not obtain credentials.
The user can obtain credentials at a later time using Network Identity
Manager. You can configure NetIdMgr to monitor network connectivity and
prompt the user to obtain credentials if s/he has none.
