I'll merge this one anyway since it's such a small change

This is a simplistic solution, simply verifying pin everytime something tries to perform a signature. The pin will be taken from the command line if given, otherwise it will be...

See also https://github.com/Yubico/yubico-piv-tool/pull/338. Still considering security implications of that one.

Thank you for the pull request! We need to check how this works on different OS:es, I suspect the error code might differ.. As a first step, what have you...

The best way to gain info about what is happening is to run the SSH agent in debug mode (-d). See here for more info https://www.ssh.com/academy/ssh/agent

And when running the agent in that mode it also helps to enable libykcs11 debugging by setting the environment variable YKCS11_DBG to 1, 2 or 3 (for the log level,...

How was the ykcs11 library (and dependencies) installed ? This looks like a code signing issue.

For my info, how did you install the newer openssh ? And did that installation also include the ssh-agent (and did you run all programs from this new installation, including...
