I'm trying to configure a Single-Sign On for our users who are outside the office and need to connect to our VPN before signing into Windows.
I've been able to configure it with this guide:
However, when it tries to connect to our VPN, we get this error:
Error Description: 766: A certificate could not be found. Connections that use the L2TP protocol over IPSec require the installation of a machine certificate, also known as a computer certificate.
Because our Meraki Security Appliance ONLY uses a pre-shared key and there's no remote access server in the picture, I believe that this is a Windows limitation (Windows is trying to protect me from using pre-shared keys). I thought this Microsoft article would help:
but it seems to discuss a remote access server which is not part of the picture.
I'm sure there are some registry tweaks needed to suppress Microsoft looking for a certificate - the question is where. Any ideas?
