Hi all, I'm a system admin from Italy, I'm trying to make a smartcard working for login. The vendor provided us with a precompiled dylib. I'm able to use the smartcard with firefox by adding a new security device and passing the dylib as the provider. Same thing with openvpn. I have searched how to add a custom provider to smartcardservices to make it use the dylib but I haven't found anything useful. Could you please give me some tips about this problem? The secure.log shows those messages when the card is inserted: Sep 28 12:59:12 gollum com.apple.SecurityServer[22]: Token reader SCM SCR 355 00 00 inserted into system Sep 28 12:59:14 gollum com.apple.SecurityServer[22]: token in reader SCM SCR 355 00 00 cannot be used (error 229) Thank you in advance, Lorenzo Dalrio
