[Tokend-Dev] Certificates from token through Tokend in built-in VPN client on Mavericks

Hello! I'm using Gemalto Tokend to access the certificates on the token. On Mac OS X 10.8 the certificates on the token are accessible via Keychain Access, Mail utilities and built-in VPN client, but after updating to 10.9 I've got an issue that certificates on the token are not listed in built-in VPN client (when selecting authentication parameters) though they are visible in Keychain Access utility. Is it a problem with Tokend used or Apple has just cut out tokend support from VPN client? Is there any workaround for the issue? Best regards, Eugene Mironenko
