In preparation to deploy our new 2012R2 RD farm, we have updated our HP thin clients to ThinPro 5.0. They connect just fine using username/password, but when I try to use a smart card, I get the message:
Please use external device to unlock the smart card.
This message is quickly replaced with:
The PIN could not be verified. The credentials could not be verified.
I thought it was a certificate issue, but the correct certs are in the server. I can use the smart card to log into the 2012R2 farm from any other laptop or desktop, just not these thin clients.
ThinPro 5.0 uses freeRDP to make RDP connections. I have tried adding some arguments to the connection parameters, but nothing works. Has anyone else encountered a problem with smart cards in freeRDP like this?
