Hello again,

The problem was that the env variable GPG_AGENT_INFO was not set for
root. So pam_poldi trys to start a new scdaemon instead of querying
gpg-agent for the current one. I dont know why, but the second scdaemon
has no access to the openpgp card.
So in /etc/sudoers i added GPG_AGENT_INFO to the env_keep line.
Now pam_poldi finds gpg-agent and therewith the currently running
scdaemon and so sudo works.
Is adding GPG_AGENT_INFO to env_keep a security risk?

Regards,
Gordian Klein
