[Pcsclite-muscle] Authenticate on OSX with NFC

[Henrik Brautaset Aronsen]

Hi.

I'm trying to authenticate myself on OSX with a ACS ACR122U USB reader 
and a NFC tag [1].  It should be doable according to Apple's "Enabling 
smart card login" document [2].  I basically need to store a key on the 
tag, and get "sc_auth hash" to show a hash from that key.


OSX's version of /usr/bin/pcsctest finds the reader and reads the tag 
without problems.  So far so good.

I found the ifdnfc project [3] which support NFC card for PKCS11 via 
OpenSC.  But I couldn't get it to build using the docs from 
nfc-tools.org [4].  I tried adding some configure parameters, but the 
build just fails searching for pcsc-lite header files:

    $ ./configure 
PCSC_CFLAGS="-I/System/Library/Frameworks/PCSC.framework/Versions/A/Headers" 
--enable-usbdropdir=/usr/libexec/SmartCardServices/driver 
CFLAGS="-framework PCSC"
    [...]
    $ make
    [...]
    clang: warning: -framework PCSC: 'linker' input unused
    ifd-nfc.c:21:10: fatal error: 'debuglog.h' file not found


So I built pcsc-lite [5], and ifdnfc builds nicely against that.  But 
pcscd doesn't seem to find the reader.  testpcsc says:

    Testing SCardIsValidContext    : Invalid handle. (don't panic)
    Testing SCardListReaders    : Cannot find a smart card reader. 
(don't panic)

Any ideas?

Best regards,
Henrik
