FIX: You are prompted for a PIN although your SSO solution is configured not to prompt you for a PIN when you run Internet Explorer 8

Applies to: Internet Explorer 8

Symptoms


Consider the following scenario:
  • You run Windows Internet Explorer 8 on a computer that is running Windows 7 Service Pack 1 (SP1) or Windows Server 2008 R2 Service Pack 1 (SP1).
  • You implement a smart card-based single sign-on (SSO) solution by using a third-party provider.
  • You use a web application that requires authentication by using client certificates that are located on the smart card.
  • The SSO solution is configured in such a way that you are not prompted for the smart card's PIN when you log on to Windows by using the smart card.
  • You close an instance of Internet Explorer that requires the smart card. However, you have another instance of Internet Explorer still open, and this instance does not require the smart card.

In this scenario, when you visit a webpage that requires the smart card, you are prompted for a PIN.

Cause


This problem occurs because, when you close an instance of Internet Explorer that requires the smart card, and another instance that does not require the smart card is still open, the smart card receives a reset. Therefore, the pin type is changed to require a PIN.

Internet Explorer performs a cleanup of the security contexts when the last instance of Internet Explorer is closed. However, when the Iexplore.exe process that used the smart card is shut down, but another instance of the Iexplore.exe process is still running, the cleanup of the security context does not occur. This causes the Smart Card service to issue a reset to the smart card. The reset from the Smart Card service then causes the SSO feature to be disabled.
