Endian 3.0 x.509 OpnVPN user certificate

Hi everybody,
I setup an Endian 3.0 community and I wish to use openVPN with x.509 auth without password.
I'm actually using an Endian 2.5.1 which let me import certificates without "challenge password" (created with openvpn's easy-rsa tools) and let my "roadwarrior" to connect to VPN without inserting credentials (so I can start OpenVPN as a service on their laptop).
On Endian 3.0 I noticed that it doesn't let me use imported certificate (CA, SERVER and CLIENT) created with openssl/pkitool. It instead creates it's own certificate.

So I tried to use the built-in certificate generator but, when generating a client certificate, the "challenge password" is a mandatory field and when a client uses that certificate the user is obviously asked to insert the certificate password.
Is there a way to pass or create certificate (with the built-in tool) without a challenge password so I can continue using OpenVPN as a service on my roadwarrior laptop?

Thank you.
