SmartCard minidriver

[ton4ik]

Hello,

We've developed a smart card minidriver for Windows XP. Now we are testing it
on
winlogon process.
After rebooting the logon with smart card works perfectly. But if I log off and
try to logon again with the same smard card, then after pin entering i receive
an error: "The requested key container does not exist on the smart
card".
If i insert card with different cardid, then logon is successful. But than i
can't use both cards for logon.
So after rebooting system i can use each card for logon onle once.


Log of logon with error:

CPGetUserKey

As i understand it, Windows store the CardId and name of the key container. The
logon process is interrupted after reading known CardId.

Any ideas, what could be wrong?
