[François Pérou]

Dear friends,

I am writing a tutorial on smartcards for strongSwan:
http://www.gooze.eu/howto/using-strongswan-with-smart-cards

I cannot configure roadwarrior Carol with smartcards:

%smartcard is not recognized:

Could you help and review these settings?
What debug information can I provide?

Kind regards,
