802.1x NPS Machine authentication

in flag

We are trying to implement 802.1x to authenticate wirelless users (Aruba Controller) through RADIUS (Windows server 2019 NPS),

For mobile phones and guests devices, we have successfully configured the authentication via user (AD Account) , but for the LAN devices (Windows 10 Domaine joined computers) we are trying the set machine authentication but unfortunatly it seems to be impossible , I have noticed that in NPS event log, the computer name is passed as a user account and not a computer account:


The Network Policy Server denied access to a user.

Contact the NPS server administrator for more information.

1- User:

- Security ID: **NULL SID**

- Account name: **host/machinename.domain.com**

- Account domain: **domain.com**

- Full account name: **domain.com\machinename$**

2- Computer:

- Security ID: ****NULL SID****

- Account Name : **-**

- Full account name: **-**

- Identifier of the called station: **10:LAN-SSID**

- Calling station identifier: **FF0000000000**


down here is our configuration of the NPS Network policy and the wireless profile on a windows 10 domain joined computer :

1- NPS Network policy-Conditions:

- Computers groups : Domain\Domain Computers

Windows 10 WLAN Card configuration :

6- Windows 10 wireless profile: EAP-MSCHAPv2

Sorry for the long post.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
