   If the PC is successfully logged on on April 1st, offline authentication will be enabled from April 1st to April 3rd.
   If the PC is successfully logged on during the above period, it is effective for an additional 3 days from the date of successful authentication.
・Please contact your administrator for the offline expiration date.
