GlobalProtect Pre-Logon Prompting for User Certificate

[Gene_Barden]

We have GlobalProtect Pre-Logon working with machine certificates however once the user logs into their laptop they are also prompted with thier User Certificate each time. There internal CA does issue machine and user certificates. Is there a way to disallow the User certificate prompt? Do we need to also use User certificates along with machine certficicates? Verion is 10.0.7 and GP 5.2.7

What setting do you have in the user portal config for certificate lookup.  If both user and machine try setting to just user.

You need to ensure the portal and gateway URLs are added to your trusted/Intranet sites in IE and ensure this setting is enabled.

For Edge and Chrome you need to configure "AutoSelectCertificateForUrls" to avoid the pop-up

This looks similar to an issue we are seeing on our Win 11 intune build and the Hello for business cert, we have added the urls and the cert to use and are able to browse to the page in a web browser without being prompted. If we remove the WHFB cert the device does not prompt. do we need to add to the ie trusted sites and enable the dont prompt for client certificate selection?

Any help or advice would be much appreciated

I have the same question. We are in the process of deploying Windows Hello for Business authentication certificates which need to be in the UPN format. The PaloAlto Global Protect Client needs the user authenticaiton certs in the CN format. The issue we are seeing is that now Global Protect is prompting for which certificate to use because there are now two authentication certificates in the users personal store. How to we force GlobalProtect Client to connect and use a certificate without prompting in the client? Is there a way to tell the GlobalProtect Client to use a certain certificate in the registry?

@rheinrich,

The easiest way to do this is to use a custom OID for the GlobalProtect certificates so that you can automatically select the proper certificate based on the OID value. That will have it default to the proper certificate without prompting for selection.
