           Summary: scard-opensc.c doesn't work without PIN
           Product: Portable OpenSSH
           Version: -current
          Platform: All
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Smartcard
        AssignedTo: openssh-bugs at mindrot.org
        ReportedBy: larsch at trustcenter.de


The function sc_prkey_op_init (in scard-opensc.c) requires for every private
key a PKCS#15 AuthenticationObject object, but the this object is optional
=> sc_prkey_op_init fails if the key is not protected by a PIN.
If sc_pkcs15_find_pin_by_auth_id retuns SC_ERROR_OBJECT_NOT_FOUND then
(most likely) a PIN is not required to use the key => sc_prkey_op_init
should simply copy the private key and return 0 (== no error).

Nils
