Problem with Keberos authentication

TKrem1 — Tue, 04 Aug 2020 12:33:54 GMT

Hello, everyone,
we are currently trying to switch our AMT wakeup to Keberos authentication. Until now, the set admin account with password was used to start and manage clients. To ensure more security, Keberos will be used now.
We have set it up according to the templates of the Intel AMT Implementation and Reference Guide. The AD integration is active, objects are created under the computer name with the addition $IME. The users in question were authorized via the SCS profile.
Here we experimented with the rights, even full access does not have the desired effect.
If an authorized user tries to send a WakeUp it will be denied with missing rights.
Are there any experiences or further tips on this topic?

Thanks
Thomas

Hello TKrem1,

Thank you for joining the Intel community.

Could you please attach some screenshots if possible of your AD setup and the error message received. We will use them to elevate your issue to our senior team.

There are some issues reported about Kerberos and AD integration. It seems that the issue comes from Windows trying to access WS-Management service. Go to run 'Services.msc' at Windows start button and locate 'Windows Remote Management (WS-Management)' observe his current status, restart the service and set it to automatic.

We will look forward for your updates.

Hello, Jose,

I checked the WS-Management service. It is set to automatic and runs during the WakeUp attempt. I restarted the service, but it didn't help.
On the screens you can see the AD configuration in the SCS profile and the error message when the user tries to do the wakeup. If the command is sent with the default admin ID, the machine responds immediately.

Regards
Thomas

Hello Jose,
we have selected PT Adfministrator for the Testuser. It was the first permission we used.
After it didn't work we also gave him the other permissions.
At the end, the user had all possible permissions.
We we have updated the respective computers provisioning between the tests.

Clusters that use Kerberos for authentication have several possible sources of potential issues, including: Failure of the Key Distribution Center (KDC) Missing Kerberos or OS packages or libraries. Incorrect mapping of Kerberos REALMs for cross-realm authentication.

Thanks to a troubleshooting we found our problem. It was homemade. The Powershell command for credential propagation required the domain in addition to the username.

Domain\Username immediately established the Keberos connection.

Thanks again.
