YubiKey NEO / Firmware 3.3.0

Hello everyone,
I'm trying to implement smartcard logon on a NEO
I'm using this tool to load the certificate on the card : viewtopic.php?f=26&t=1703

I'm using the "Smartcard User" template on my AD Certificate Authority
I'm issuing a ECDH_P256 certificate (GPO enabling ECDH certificate usage is present)

When I try to use it, like in Remote Desktop, it seems to seek a certificate for 10 seconds on the Yubikey
then it says "No valid certificate"

I'm trying on a domain computer aswell on a non-domain computer and it's the same "bug"

Any idea how to implement this properly ? Can't find more ressources

Regards,
Thomas

I think I saw your other post, but this is how I solved it:

Hello ActualReverend

Thanks for your reply.
I'm already using your script to upload the pfx to the YubiKey, but when I get on the smartcard
prompt it says there is no valid certificate (and i'm using the Smartcard user template from ADCS)

Any idea ?

Thanks
