Hi,

thanks for your reply. Please find attached the debug trace of the openssh-client:

Permission denied (publickey).

If you have a look at line 8, you'll see that no keys were found. I'm wondering why. I assume that the Safnet driver is not behaving the way as expected from the pkcs11-helper, which is used by openssh-client (please correct me if I'm wrong).
