Globalprotect Credential Provider not capturing automatic logon

[ColdSteel]

Overview:

I have Windows 10 Desktop machine which runs in KIOSK mode, it automatically logs in to my dedicated AD KIOSK user through setting the AutoAdminLogon Registry keys.

We are using GlobalProtect for our user identity when inside of the corporate network combined with the GlobalProtect Windows login credential provider to allow SSO authentication.

The issue:

When the PC signs in using the AutoAdminLogon registry, GlobalProtect can’t capture the login credentials due to Windows using its native credential provider.

Attempted Solutions/Diag:

• When signing in interactively with the computer, SSO works as expected.
• When entering the AD KIOSK user’s credentials into GlobalProtect after using the auto logon it authenticates fine and remains until the next reboot.
• I have tried to enforce GlobalProtect as the default credential provider by following ‘Deploy GlobalProtect Credential Provider Settings in the Windows Registry’ step 2, this did not work so reverted the change.
• I tried to force credential capture by telling GlobalProtect to capture the GUID ID of the Windows credential provider by ‘SSO Wrapping for Third-Party Credentials with the Windows Registry’ as per documentation but was unsuccessful.

I am aware as a work around I could make an identity policy or firewall policy which could be based on IP or AD polling, but I am wanting to try keep things simple and aligned.

Have I overlooked something? Has someone else managed to work a solution to this?
Or should I be using a different method to auto logon these machines which may work better with GlobalProtect?

Software Version              10.2.4-h4
GlobalProtect Agent        6.1.1

Thanks in advance for your time.
