Global Protect - valid certificate when using Azure SAML authentication

MichaelMedwid — Tue, 02 Nov 2021 20:23:36 GMT

In logging I can see that SAML authentication via Azure is succeeding. However my GP client is

failing to successfully connect I believe for some deficiency in the certificate. I have a self signed

certificate in a cert profile at the portal and gateway for this GP On Demand setup. Authentication

is set to require certificate *and* user ID/password. (Soon this will be MFA. But first things first.)

Can a self signed certificate serve the need in this case? What properties would need to be

in such a self signed certificate to get GP connect? Thank you.

@MichaelMedwid,

First, I would never recommend using a self-signed certificate with GlobalProtect. Either get the certificate issued by your internal CA or have it signed by a public trusted CA. Second, taking away SAML authentication for a second is this an existing working configuration or something you're just trying to get setup?

As BPry mentioned, you should get a CA certificate for the GP portal and gateways.
In addition to that, you need to export the Microsoft Azure Federated SSO Certificate from the Azure Portal and import it to the firewall (Device -> Certificate Management -> Certificates).

The following KB shows how to set up Azure SAML authentication with GlobalProtect, but this export/import certificate step is missing.

Hope this helps!
