Firstly, thanks for some great software :-) I've been using gpg for a couple
of months now, including using poldi to log me in and unlock sessions with my
cryptocard from the FSFE.
However, I'm having a problem using gpg-agent to cache the smartcard's PIN
along with the poldi PAM module. Specifically, once gpg-agent has cached the
PIN, poldi no longer works, meaning that I can't use it for authenticating
su / sudo commands or for unlocking the session or logging in on another
I found this in the list archives:

Is there any progress towards making this work yet? Any fix / patch /
