Post subject:  Yubikey And OpenVpn Access Server Authentication ?
I have OpenVpn Access Server(Ubuntu) running at my home PC on Vmware that i always connect to from school.
I am wondering how, if possible i can integrate my yubikey to that for a 2-factor authentication.
Any knowledge that can get me moving in the right direction would be great.

The step by step instructions for integrating YubiKey based authentication to the OpenVPN server using the Yubico PAM module can be found at the link below:

We hope this helps!

What about the fact that both OPEN VPN and the Windows VPN client are limited to 48 character password? As the OTP is 44 chars, this only leaves you with a 4 char password, or, if you use more, your OTP is truncated, and will not validate?

I have read the link posted above, and it does not address this question? I would really like the answer to this one as it has stumped me!

Here is a prior thread addressing this: http://forum.yubico.com/viewtopic.php?f=8&t=471

Considering what Yubico says about Radius and VPN: http://www.yubico.com/radius
Quote:
A RADIUS server combined with an industry standard VPN or SSL based VPN solution provides a robust and flexible remote access solution. In any remote access scenario two-factor authentication is highly recommended


I think there needs to be a valid solution to this issue - and not one that involves limiting user passwords to less than or equal to 4 chars!
