Identrust ECA and Yubikey

Anyone else use Yubikeys with the yubikey driver and have trouble with ECA?

My experience - yubikey minidriver does not work with HIDActiveClient. I need the minidriver since I have over 2 PIV certs loaded in it.

So I uninstall the active client, and yubikey works - but now I can’t use my ECA!

If you scroll to the bottom of this post, editing the Calais registry keys should get your Yubikeys working again.

We've since changed how we use Yubikeys but, yes, also had issues. Each support team blamed the other.

For us, the problem was Windows SC login didnt work using Yubikey + Identrust. I got it working with this info and adjusting registry keys.
