How to connect to a VPN with a certificate using the shipped VPN client within Mac OS X 10.6.6

certificatekeychainmac-osxvpn

I'm trying to set up a VPN on a Mac OS X to connect to OpenVPN server.
I've been provided the following files:

  • client.key
  • client.crt
  • ta.key
  • ca.crt

I added to the Keychain System client.crt & ca.crt, it worked, but when I try to use a certificate in the VPN authentification configuration I get the following error :

Certificate authentication cannot be
used because your keychain does not
contain any suitable certificates. Use
Keychain Access to import the
appropriate certificates into your
keychain. If you do not have the
certificates required for
authentication, contact your network
administrator.

Any ideas?

This is not going to work. The built-in VPN uses either PPTP or IPSec while OpenVPN uses SSL, both products are not compatible. Use Tunnelblick instead.
