A PAM module implementing challenge/response based authentication through the OpenPGP smartcard
This method establishs the mapping between user accounts and smartcards through a locally administered database.
This method uses the PKI infrastructure provided by Dirmngr for validating certificates. OpenPGP smartcards are associated with X509 certificates through the smartcard's ``url'' field; the user account name to use for authentication is extracted from the certificate.
Since Poldi is a PAM module, it's slightly misleading to speak of Poldi screenshots. Instead we have screenshots of PAM-enabled applications that are configured to use Poldi. (see the screenshots section)
Installation instructions are contained in the Poldi manual, which is distributed in the Poldi source code package.
