I have a user using a CAC card with Windows 7. We are using the built in smart card provider vs ActiveClient and this has been working well for some time now.
Recently though when the user tries to send signed mail from Outlook 2007, he is prompted at least three times for his PIN by the Microsoft Smart Card Provider before finally working. We are sure the PIN number is correct, but its become quite a nuisance to have to enter the PIN so many times.
Can anyone offer any advice in troubleshooting this?
