Symptoms
Consider the following scenario:
-
You use a Single Sign-On (SSO) smart card to log on a Windows 7-based computer in a domain environment. Therefore, you are automatically signed in to all applications that support smart card authentication.
-
You successfully log on to a computer that is running Windows 7 by using a smart card.
-
You try to connect to a wireless network that requires authentication.
In this scenario, you are prompted to enter your personal identification number (PIN) unexpectedly.
Cause
This issue occurs because the Rstls.dll component in Windows 7 does not support the EmptyPinType feature.
