Does WinLogon call PC/SC directly or use CryptoAPI?

In my earlier post, I didn't frame my question correctly.
It is not whether WinLogon is smart card aware or. Of course it is. I guess
my question should be "Does WinLogon call PC/SC directly (to make sure
whether a smart card is present) or does it call CryptoAPI"? The difference
matters to me as I would have to implement PC/SC driver if WinLogon makes
PC/SC calls directly, as I have explained in the e-mail below.
