Globalprotect pre-logon VPN and Azure AD Hybrid join

Hello everyone,

We are looking at using GP for the purposes of joining offsite computers to our domain via a process called offsite Azure Hybrid AD join. More details:

The basic premise is that the GP establishes a connection before login and then the user simply logs in, as if they were on the LAN.

I have set this up and it works well, but there is one problem that probably scuppers the whole thing: in order to work, the computer needs BOTH a computer certificate and a user cerficicate. This is a problem because the VPN needs to connect BEFORE the user logs in, so there will be no user certificate available. I spoke to Palo support and they told me this is by design and pre-logon needs both certificates.

 

This seems strange to me...surely this can work with only computer certificates?

 

Settings

Portal:

  • Certificate profile containing internal PKI root and subordinate
  • Authentication profile: points at an internal Radius server
  • Cookies enabled for authentication override
  • Config selection criteria: "any" user/user group
  • Single external gateway
  • Connect method: Pre-logon (always on)

Gateway:

  • Certificate profile containing internal PKI root and subordinate
  • Authentication profile: points at an internal Radius server
  • Cookies enabled for authentication override

If anyone can offer any advise as to how to get this to work with only computer certificates that would be great.

 

Thanks, Brian

It actually looks like this configuration is correct. I reset my test laptop back to factory defaults and now it just works with only the machine certificate.
