Microsoft NPS Policy Setup for PortServer TS 3 M MEI

Trying to setup RADIUS authentication on PortServer TS 3 M MEI units.
I have a Microsoft 2012 NPS server which is working on other devices.
Is there a doc or any help on how to configure the NPS Policy for DIGI’s?
In the NPS logs I see the request and access granted but the DIGI comes back with authentication failed on both SSH and WEB Interface. Can still login with local username/pw.
Tks.

With PortServer TS products, only root can access the Web, meaning there is no option to use radius to authenticate via HTTP/HTTPS.

Also, if I’m reading the following correctly, the user should not exist on the PortServer unit for SSH connectivity:
