3. On the next page select the smart card enrollment certificate template you have duplicated or modified. (If you didn’t find one, make sure the certificate template has been created and issued that you can see at certsrv.msc)

4. Click Next and enter the target user account(must in the domain) you are going to enroll the certificate on the behalf of.

5. Click Next. The following dialog may appear asking you to insert the user’s smart card if it is not already inserted. Enter the PIN.


6. If the enrollment is successful, the dialog will show the following:

  • If you choose the third part crypt provider instead of the key to generate key-pair, there will be a prompt to let user allow the devices to be accessed.
  • After the enrollment is success, the smart card is ready to be used for that user. You can enroll for other users or close the window.
  • At this point, the target user is now able to logon to this domain with that Smartcard.
