[strongSwan] Trouble configuring vpn connection to strongswan using smartcard

[Nathan Hüsken]

Hey,

Ok, now I am a little confused.

I wanted to use the network-manager (in the end, the config has to be usable by people scared of the command line).
There is an option: "Smartcard". If choose it, it asks me for the pin of the smart card (but complains, that there are not usable certificates on the smartcard).

If charon-nm doest not support reading the private key from the smartcard, what is the point of this option?

What am I missing here?

Many thanks!
Nathan
