Re: [Opensc-devel] OpenSC 0.17 breaks PIV card auth on Safari/Citrix Receiver On macOS 10.12+

[Douglas E E. <dee...@gm...>]

It sounds like one or both of the MacOS smart card code or OpenSC are
accessing the card in exclusive mode. Both have support for PIV cards
and use pcsc to access the reader.

I do not use MacOS, but there are others on this mailing list that do
and use PIV cards. I am surprised no else has responded.

https://github.com/OpenSC/OpenSC/wiki/Using-OpenSC

See the OpenSC opensc.conf file debug= and debug_file= parameters to turn on debugging.

Also look at the connect_exclusive, disconnect_action, transaction_end_action
and reconnect_action. The default of disconnect_action=reset may be a problem.
I would set it to disconnect_action=leave; But the MaocOS code may also be
causing problems.
