Symptoms

When you unlock a computer that is running Windows 7 or Windows Server 2008 R2 by using a smart card, you may have to wait for up to 30 seconds before the desktop is displayed. However, the unlocking process is supposed to complete within several seconds.

Note After this issue occurs one time, every successive unlocking operation that uses the smart card will be affected until you restart the computer.

Cause

This issue occurs because the smart card module incorrectly manages its cache. This causes a long delay if the smart card is accessed multiple times. The expected behavior is that the smart card module uses cached information when it performs Kerberos authentication.
