## What you need to know

Which authentication layer is being tested when an administrator opens Windows Admin Center?

## Potentially affected

Teams reviewing identity-provider and authentication options for a Windows Admin Center gateway.

## DSE recommendation

Draw the two access stages and assign an owner to each.

## Article

## Source facts

Windows Admin Center gateway administrators can select Active Directory or local groups, or Microsoft Entra ID, as the identity provider. Requiring Microsoft Entra authentication for the gateway enables use of its Conditional Access and multifactor authentication capabilities. Access to the gateway does not itself grant access to managed servers. [Microsoft Learn](https://learn.microsoft.com/en-us/windows-server/manage/windows-admin-center/plan/user-access-options).

## Applicability

Identify whether the current question concerns gateway sign-in or authorization on a particular managed server. Inventory the chosen identity provider and any applicable access policy. Do not treat a successful gateway challenge as evidence that server permissions are correct.

## DSE recommendation

Draw the two access stages and assign an owner to each. For an Entra-backed gateway, have the identity owner define the intended Conditional Access test conditions and recovery access. Have the server owner independently approve the target permissions. Use a pilot administrator account with known memberships so an unexpected result can be traced to the correct layer without widening either permission set.

## Verification

Test gateway sign-in under an allowed condition and an intentionally denied condition. For the allowed gateway session, attempt access to both an approved server and a server outside the pilot permission set. Record the policy and authorization outcome separately, including the stage at which a denied attempt stopped.
