We have tons of Red Hat 8 workstations that authenticate using a certificate / dot1x / freeradius and work perfectly. I cannot get the Windows 10 workstation to work, authenticate with dot1x, or receive its proper VLAN. I've searched around for answers and changed a few things noted below.
OK...
Added this line in the raddb/mods-config/preprocess/hints file: DEFAULT Prefix == "host/", Strip-User-Name = Yes Service-Type = Framed-User
Added this line in raddb/sites-enabled/default.noldap file: authorize if ("%{User-Name}" =~ /^host\/(.*)/) { update request { Stripped-User-Name = "%{1}" } }
Why were these changes made?
This is the workstation in the raddb/users file: wuk-emewks265a-swfo-san.ssd.goes Service-Type = Framed-User, Tunnel-Type = VLAN, Tunnel-Medium-Type = IEEE-802, Tunnel-Private-Group-ID = "602"
There's no password, which might be an issue.

Ok, so EAP starts.

The server is doing EAP-MD5. While this is the default, you might change that in mods-enabled/eap. Perhaps setting the default to TTLS or PEAP might help.

The server replies, and the Windows machine never continues the EAP conversation. You'll have to look at the logs on the Windows machine to see why this happens. But changing the default EAP type to PEAP might help, too. In short, you can't debug Windows issues by looking at the FreeRADIUS logs. Alan DeKok.
