Default GINA for Smart Card logon


Recently, I am writing a GINA for Smart Card logon.But I have a problem.

First, I installed PC/SC driver and invoked a function in WlxInitialize
like this
WlxSetOption(g_hWlx, WLX_OPTION_USE_SMART_CARD, 1, NULL);When I remove the
smart card,winlogon looks as if it can not receive the WLX_SAS_TYPE_SC_REMOVE
event.I do not known why. I think windows should send this message to
winlogon.At last, I create a thread and try to get the message
WM_DEVICECHANGE. If it occurs, I will invoke the funtion WlxSasNotify.So I
can receive the WLX_SAS_TYPE_SC_REMOVE event.But there is another problem.My
computer may stop at the winlogon desktop and the default desktop may be
hidden.

Who can give me some solution or suggestion ? And my os is windows xp sp2
Thanks very much.

Winlogon already supports smartcards. Why are you writing a new GINA? And
you do know the GINA is gone in Windows Vista/Server 2008, right?

You are right. But Windows XP will exist for a long time.So my company need
to support it.
Winlogon supports smartcards.But how can I receive WLX_SAS_TYPE_SC_REMOVE
in the funtion WlxLoggedOnSAS.When I remove smart cards, Winlogon does not
response to the action.

Are you trying to control what happens when people remove their smart cards
after logging on? We've already got group policy for that:

Computer Configuration | Windows Settings | Security Settings | Local
Policies | Security Options |
Interactive logon: Smart card removal behavior = No action, Lock
workstation, or Force logoff
