- The Smart card is required for interactive logon user account property is set on a computer that is running Microsoft Windows XP.
- The smart card is lost or damaged. The user is temporarily permitted to log on by entering a user name and a password.
- Later, a new smart card is issued to the user. The user is again required to log on only by using a smart card.
In this scenario, the user can still log on offline with the temporary user name and password.
This problem occurs because the user name and the password are cached on the computer.
