Microsoft Entra integration with MDM

Microsoft Entra ID is the world's largest enterprise cloud identity management service. It's used by organizations to access Microsoft 365 and business applications from Microsoft and third-party software as a service (SaaS) vendors. Many of the rich Windows experiences for organizational users (such as store access or OS state roaming) use Microsoft Entra ID as the underlying identity infrastructure. Windows integrates with Microsoft Entra ID, allowing devices to be registered in Microsoft Entra ID and enrolled into MDM in an integrated flow.

Once a device is enrolled in MDM, the MDM:

  • Can enforce compliance with organization policies, add or remove apps, and more.
  • Can report a device's compliance in Microsoft Entra ID.
  • Microsoft Entra ID can allow access to organization resources or applications secured by Microsoft Entra ID to devices that comply with policies.

To support these rich experiences with their MDM product, MDM vendors can integrate with Microsoft Entra ID.

Integrated MDM enrollment and UX

There are several ways to connect your devices to Microsoft Entra ID:

In each scenario, Microsoft Entra authenticates the user and the device. It provides a verified unique device identifier that can be used for MDM enrollment. The enrollment flow provides an opportunity for the MDM service to render its own UI, using a web view. MDM vendors should use the UI to render the Terms of Use (TOU), which can be different for company-owned and bring-your-own-device (BYOD) devices. MDM vendors can also use the web view to render more UI elements, such as asking for a one-time PIN.

In Windows 10, the web view during the out-of-the-box scenario is displayed as full-screen by default, providing MDM vendors with the capability to create a seamless edge-to-edge user experience. However, in Windows 11 the web view is rendered within an iframe. It's important that MDM vendors who integrate with Microsoft Entra ID respect the Windows design guidelines. This step includes using a responsive web design and respecting the Windows accessibility guidelines. For example, include the forward and back buttons that are properly wired to the navigation logic. More details are provided later in this article.

For Microsoft Entra enrollment to work for an Active Directory Federated Services (AD FS) backed Microsoft Entra account, you must enable password authentication for the intranet on the ADFS service. For more information, see Configure Azure MFA as authentication provider with AD FS.

Once a user has a Microsoft Entra account added to Windows and enrolled in MDM, the enrollment can be managed through Settings > Accounts > Access work or school. Device management of either Microsoft Entra join for organization scenarios or BYOD scenarios is similar.

Note

Users can't remove the device enrollment through the Access work or school user interface because management is tied to the Microsoft Entra ID or work account.

MDM endpoints involved in Microsoft Entra integrated enrollment

Microsoft Entra MDM enrollment is a two-step process:

  1. Display the Terms of Use and gather user consent: This consent is a passive flow where the user is redirected in a browser control (webview) to the URL of the Terms of Use of the MDM.
  2. Enroll the device: This step is an active flow where Windows OMA DM agent calls the MDM service to enroll the device.

To support Microsoft Entra enrollment, MDM vendors must host and expose a Terms of Use endpoint and an MDM enrollment endpoint.

  • Terms of Use endpoint: Use this endpoint to inform users of the ways in which their organization can control their device. The Terms of Use page is responsible for collecting user's consent before the actual enrollment phase begins.

    It's important to understand the Terms of Use flow is an "opaque box" to Windows and Microsoft Entra ID. The whole web view is redirected to the Terms of Use URL. The user should be redirected back after approving or rejecting the Terms. This design allows the MDM vendor to customize their Terms of Use for different scenarios. For example, different levels of control are applied on BYOD vs. organization-owned devices. Or, implement user/group based targeting, like users in certain geographies may have stricter device management policies.

    The Terms of Use endpoint can implement more business logic, such as collecting a one-time PIN provided by IT to control device enrollment. However, MDM vendors must not use the Terms of Use flow to collect user credentials, which can be a degraded user experience. It's not needed, since part of the MDM integration ensures that the MDM service can understand tokens issued by Microsoft Entra ID.

  • MDM enrollment endpoint: After the users accept the Terms of Use, the device is registered in Microsoft Entra ID. Automatic MDM enrollment begins.

    The following diagram illustrates the high-level flow involved in the actual enrollment process. The device is first registered with Microsoft Entra ID. This process assigns a unique device identifier to the device and presents the device with the ability to authenticate itself with Microsoft Entra ID (device authentication). Then, the device is enrolled for management with the MDM. This step calls the enrollment endpoint and requests enrollment for the user and device. At this point, the user has been authenticated and device has been registered and authenticated with Microsoft Entra ID. This information is available to the MDM in the form of claims within an access token presented at the enrollment endpoint.

    Microsoft Entra enrollment flow

    The MDM is expected to use this information about the device (Device ID) when reporting device compliance back to Microsoft Entra ID using the Microsoft Graph API. A sample for reporting device compliance is provided later in this article.

Make MDM a reliable party of Microsoft Entra ID

To participate in the integrated enrollment flow outlined in the previous section, the MDM must consume access tokens issued by Microsoft Entra ID. To report compliance with Microsoft Entra ID, the MDM must authenticate itself to Microsoft Entra ID and obtain authorization in the form of an access token that allows it to invoke the Microsoft Graph API.

Cloud-based MDM

A cloud-based MDM is a SaaS application that provides device management capabilities in the cloud. It's a multi-tenant application. This application is registered with Microsoft Entra ID in the home tenant of the MDM vendor. When an IT admin decides to use this MDM solution, an instance of this application is made visible in the tenant of the customer.

The MDM vendor must first register the application in their home tenant and mark it as a multi-tenant application. For more information about how to add multi-tenant applications to Microsoft Entra ID, see the Integrate an app that authenticates users and calls Microsoft Graph using the multi-tenant integration pattern (SaaS) code sample on GitHub.

Note

For the MDM provider, if you don't have an existing Microsoft Entra tenant with a Microsoft Entra subscription that you manage, follow these step-by-step guides:

The MDM application uses keys to request access tokens from Microsoft Entra ID. These keys are managed within the tenant of the MDM provider and not visible to individual customers. The same key is used by the multi-tenant MDM application to authenticate itself with Microsoft Entra ID, in the customer tenant where the managed device belongs.

Note

All MDM apps must implement Microsoft Entra v2 tokens before we certify that integration works. Due to changes in the Microsoft Entra app platform, using Microsoft Entra v2 tokens is a hard requirement. For more information, see Microsoft identity platform access tokens.

On-premises MDM

An on-premises MDM application is different than a cloud MDM. It's a single-tenant application that is present uniquely within the tenant of the customer. Customers must add the application directly within their own tenant. Also, each instance of an on-premises MDM application must be registered separately and have a separate key for authentication with Microsoft Entra ID.

To add an on-premises MDM application to the tenant, use the Microsoft Entra service, specifically under Mobility (MDM and MAM) > Add application > Create your own application. Administrators can configure the required URLs for enrollment and Terms of Use.

Your on-premises MDM product must expose a configuration experience where administrators can provide the client ID, app ID, and the key configured in their directory for that MDM application. You can use this client ID and key to request tokens from Microsoft Entra ID when reporting device compliance.

For more information about registering applications with Microsoft Entra ID, see Basics of Registering an Application in Microsoft Entra ID.

Key management and security guidelines

The application keys used by your MDM service are a sensitive resource. They should be protected and rolled over periodically for greater security. Access tokens obtained by your MDM service to call the Microsoft Graph API are bearer tokens and should be protected to avoid unauthorized disclosure.

For security best practices, see Microsoft Azure Security Essentials.

For cloud-based MDM, you can roll over the application keys without requiring a customer interaction. There's a single set of keys across all customer tenants managed by the MDM vendor in their Microsoft Entra tenant.

For the on-premises MDM, the Microsoft Entra authentication keys are within the customer tenant and the customer's administrator must roll over the keys. To improve security, provide guidance to customers about rolling over and protecting the keys.

IT administrators use the Microsoft Entra app gallery to add an MDM for their organization to use. The app gallery is a rich store with over 2400 SaaS applications that are integrated with Microsoft Entra ID.

Note

You should work with the Microsoft Entra engineering team if your MDM application is cloud-based and needs to be enabled as a multi-tenant MDM application

To publish your application, submit a request to publish your application in Microsoft Entra application gallery

The following table shows the required information to create an entry in the Microsoft Entra app gallery.

Item Description
Application ID The client ID of your MDM app that is configured within your tenant. This ID is the unique identifier for your multi-tenant app.
Publisher A string that identifies the publisher of the app.
Application URL A URL to the landing page of your app where your administrators can get more information about the MDM app and contains a link to the landing page of your app. This URL isn't used for the actual enrollment.
Description A brief description of your MDM app, which must be under 255 characters.
Icons A set of logo icons for the MDM app. Dimensions: 45 X 45, 150 X 122, 214 X 215

There are no special requirements for adding on-premises MDM to the app gallery. There's a generic entry for administrators to add an app to their tenant.

However, key management is different for on-premises MDM. You must obtain the client ID (app ID) and key assigned to the MDM app within the customer's tenant. The ID and key obtain authorization to access the Microsoft Graph API and report device compliance.

Themes

The pages rendered by the MDM in the integrated enrollment process must use Windows templates (Download the Windows templates and CSS files (1.1.4)). These templates are important for enrollment during the Microsoft Entra join experience in OOBE where all of the pages are edge-to-edge HTML pages. Avoid copying the templates because it is difficult to get the button placement right.

There are three distinct scenarios:

  1. MDM enrollment as part of Microsoft Entra join in Windows OOBE.
  2. MDM enrollment as part of Microsoft Entra join, after Windows OOBE from Settings.
  3. MDM enrollment as part of adding a Microsoft work account on a personal device (BYOD).

These scenarios support Windows Pro, Enterprise, and Education.

The CSS files provided by Microsoft contain version information and we recommend that you use the latest version. There are separate CSS files for Windows client devices, OOBE, and post-OOBE experiences. Download the Windows templates and CSS files (1.1.4).

  • For Windows 10, use oobe-desktop.css
  • For Windows 11, use oobe-light.css

Using themes

An MDM page must adhere to a predefined theme depending on the scenario that is displayed. For example, if the CXH-HOSTHTTP header is FRX, which is the OOBE scenario, then the page must support a dark theme with blue background color, which uses WinJS file Ui-dark.css ver 4.0 and oobe-desktop.css ver 1.0.4.

CXH-HOST (HTTP HEADER) Scenario Background Theme WinJS Scenario CSS
FRX OOBE Dark theme + blue background color Filename: Ui-dark.css Filename: oobe-dekstop.css
MOSET Settings/Post OOBE Light theme Filename: Ui-light.css Filename: settings-desktop.css

Terms of Use protocol semantics

The MDM server hosts the Terms of Use endpoint. During the Microsoft Entra join protocol flow, Windows does a full-page redirect to this endpoint. This redirect enables the MDM to display the terms and conditions that apply. It allows the user to accept or reject the terms associated with enrollment. After the user accepts the terms, the MDM redirects back to Windows for the enrollment process to continue.

Redirect to the Terms of Use endpoint

This redirect is a full page redirect to the Terms of User endpoint hosted by the MDM. Here's an example URL, https://fabrikam.contosomdm.com/TermsOfUse.

The following parameters are passed in the query string:

Item Description
redirect_uri After the user accepts or rejects the Terms of Use, the user is redirected to this URL.
client-request-id A GUID that is used to correlate logs for diagnostic and debugging purposes. Use this parameter to log or trace the state of the enrollment request to help find the root cause of failures.
api-version Specifies the version of the protocol requested by the client. This value provides a mechanism to support version revisions of the protocol.
mode Specifies that the device is organization owned when mode=azureadjoin. This parameter isn't present for BYOD devices.

Access token

Microsoft Entra ID issues a bearer access token. The token is passed in the authorization header of the HTTP request. Here's a typical format:

Authorization: Bearer CI6MTQxmCF5xgu6yYcmV9ng6vhQfaJYw...

The following claims are expected in the access token passed by Windows to the Terms of Use endpoint:

Item Description
Object ID Identifier of the user object corresponding to the authenticated user.
UPN A claim containing the user principal name (UPN) of the authenticated user.
TID A claim representing the tenant ID of the tenant. In the example above, it's Fabrikam.
Resource A sanitized URL representing the MDM application. Example: https://fabrikam.contosomdm.com

Note

There's no device ID claim in the access token because the device may not yet be enrolled at this time.

To retrieve the list of group memberships for the user, you can use the Microsoft Graph API.

Here's an example URL:

https://fabrikam.contosomdm.com/TermsOfUse?redirect_uri=ms-appx-web://ContosoMdm/ToUResponse&client-request-id=34be581c-6ebd-49d6-a4e1-150eff4b7213&api-version=1.0
Authorization: Bearer eyJ0eXAiOi

The MDM is expected to validate the signature of the access token to ensure it is issued by Microsoft Entra ID and that the recipient is appropriate.

Terms of Use content

The MDM may do other more redirects as necessary before displaying the Terms of Use content to the user. The appropriate Terms of Use content should be returned to the caller (Windows) so it can be displayed to the end user in the browser control.

The Terms of Use content should contain the following buttons:

  • Accept - the user accepts the Terms of Use and proceeds with enrollment.
  • Decline - the user declines and stops the enrollment process.

The Terms of Use content must be consistent with the theme used for the other pages rendered during this process.

Terms of Use endpoint processing logic

At this point, the user is on the Terms of Use page shown during the OOBE or from the Setting experiences. The user has the following options on the page:

  • User clicks on the Accept button - The MDM must redirect to the URI specified by the redirect_uri parameter in the incoming request. The following query string parameters are expected:
    • IsAccepted - This Boolean value is required, and must be set to true.
    • OpaqueBlob - Required parameter if the user accepts. The MDM may use this blob to make some information available to the enrollment endpoint. The value persisted here is made available unchanged at the enrollment endpoint. The MDM may use this parameter for correlation purposes.
    • Here's an example redirect - ms-appx-web://MyApp1/ToUResponse?OpaqueBlob=value&IsAccepted=true
  • User clicks on the Decline button - The MDM must redirect to the URI specified in redirect_uri in the incoming request. The following query string parameters are expected:
    • IsAccepted - This Boolean value is required, and must be set to false. This option also applies if the user skipped the Terms of Use.
    • OpaqueBlob - This parameter isn't expected to be used. The enrollment is stopped with an error message shown to the user.

Users skip the Terms of Use when they're adding a Microsoft work account to their device. However, they can't skip it during the Microsoft Entra join process. Don't show the decline button in the Microsoft Entra join process. The user can't decline the MDM enrollment if configured by the administrator for the Microsoft Entra join.

We recommend that you send the client-request-id parameters in the query string as part of this redirect response.

Terms Of Use Error handling

If an error occurs during the terms of use processing, the MDM can return two parameters - an error and error_description parameter in its redirect request back to Windows. The URL should be encoded, and the contents of the error_description should be in English plain text. This text isn't visible to the end-user. So, localization of the error_description text isn't a concern.

Here's the URL format:

HTTP/1.1 302
Location:
<redirect_uri>?error=access_denied&error_description=Access%20is%20denied%2E

Example:
HTTP/1.1 302
Location: ms-appx-web://App1/ToUResponse?error=access_denied&error_description=Access%20is%20denied%2E

The following table shows the error codes.

Cause HTTP status Error Description
api-version 302 invalid_request unsupported version
Tenant or user data are missing or other required prerequisites for device enrollment aren't met 302 unauthorized_client unauthorized user or tenant
Microsoft Entra token validation failed 302 unauthorized_client unauthorized_client

Management protocol with Microsoft Entra ID

There are two different MDM enrollment types that integrate with Microsoft Entra ID, and use Microsoft Entra user and device identities. Depending on the enrollment type, the MDM service may need to manage a single user or multiple users.

  • Multiple user management for Microsoft Entra joined devices

    In this scenario, the MDM enrollment applies to every Microsoft Entra user who signs in to the Microsoft Entra joined device - call this enrollment type a device enrollment or a multi-user enrollment. The management server can determine the user identity, determine what policies are targeted for this user, and send corresponding policies to the device. To allow management server to identify current user that is logged on to the device, the OMA DM client uses the Microsoft Entra user tokens. Each management session contains an extra HTTP header that contains a Microsoft Entra user token. This information is provided in the DM package sent to the management server. However, in some circumstances Microsoft Entra user token isn't sent over to the management server. One such scenario happens immediately after MDM enrollments completes during Microsoft Entra join process. Until Microsoft Entra join process is finished and Microsoft Entra user signs on to the machine, Microsoft Entra user token isn't available to OMA-DM process. Typically, MDM enrollment completes before Microsoft Entra user sign in to machine and the initial management session doesn't contain a Microsoft Entra user token. The management server should check if the token is missing and only send device policies in such case. Another possible reason for a missing Microsoft Entra token in the OMA-DM payload is when a guest is logged on to the device.

  • Adding a work account and MDM enrollment to a device:

    In this scenario, the MDM enrollment applies to a single user who initially added their work account and enrolled the device. In this enrollment type, the management server can ignore Microsoft Entra tokens that may be sent over during management session. Whether Microsoft Entra token is present or missing, the management server sends both user and device policies to the device.

  • Evaluating Microsoft Entra user tokens:

    The Microsoft Entra token is in the HTTP Authorization header in the following format:

    Authorization:Bearer <Azure AD User Token Inserted here>
    

    More claims may be present in the Microsoft Entra token, such as:

    • User - user currently logged in
    • Device compliance - value set the MDM service into Azure
    • Device ID - identifies the device that is checking in
    • Tenant ID

    Access tokens issued by Microsoft Entra ID are JSON web tokens (JWTs). Windows presents a valid JWT token to the MDM enrollment endpoint to start the enrollment process. There are a couple of options to evaluate the tokens:

    • Use the JWT Token Handler extension for WIF to validate the contents of the access token and extract claims required for use. For more information, see JwtSecurityTokenHandler Class.
    • Refer to the Microsoft Entra authentication code samples to get a sample for working with access tokens. For an example, see NativeClient-DotNet.

Device Alert 1224 for Microsoft Entra user token

An alert is sent when the DM session starts and there's a Microsoft Entra user logged in. The alert is sent in OMA DM package #1. Here's an example:

Alert Type: com.microsoft/MDM/AADUserToken

Alert sample:
<SyncBody>
 <Alert>
  <CmdID>1</CmdID>
  <Data>1224</Data>
  <Item>
   <Meta>
    <Type xmlns= "syncml:metinf ">com.microsoft/MDM/AADUserToken</Type>
   </Meta>
   <Data>UserToken inserted here</Data>
  </Item>
 </Alert>
 ... other XML tags ...
</SyncBody>

Determine when a user is logged in through polling

An alert is sent to the MDM server in DM package #1.

  • Alert type - com.microsoft/MDM/LoginStatus
  • Alert format - chr
  • Alert data - provide sign-in status information for the current active logged in user.
    • Signed-in user who has a Microsoft Entra account - predefined text: user.
    • Signed-in user without a Microsoft Entra account- predefined text: others.
    • No active user - predefined text:none

Here's an example.

<SyncBody>
 <Alert>
  <CmdID>1</CmdID>
  <Data>1224</Data>
  <Item>
   <Meta>
    <Type xmlns= "syncml:metinf ">com.microsoft/MDM/LoginStatus</Type>
   </Meta>
   <Data>user</Data>
  </Item>
 </Alert>
 ... other XML tags ...
</SyncBody>

Report device compliance to Microsoft Entra ID

Once a device is enrolled with the MDM for management, organization policies configured by the IT administrator are enforced on the device. MDM evaluates the device compliance with configured policies and then reports it to Microsoft Entra ID. This section covers the Graph API call you can use to report a device compliance status to Microsoft Entra ID.

For a sample that illustrates how an MDM can obtain an access token using OAuth 2.0 client_credentials grant type, see Daemon_CertificateCredential-DotNet.

  • Cloud-based MDM - If your product is a cloud-based multi-tenant MDM service, you have a single key configured for your service within your tenant. To obtain authorization, use this key to authenticate the MDM service with Microsoft Entra ID.
  • On-premises MDM - If your product is an on-premises MDM, customers must configure your product with the key used to authenticate with Microsoft Entra ID. This key configuration is because each on-premises instance of your MDM product has a different tenant-specific key. So, you may need to expose a configuration experience in your MDM product that enables administrators to specify the key to be used to authenticate with Microsoft Entra ID.

Use Microsoft Graph API

The following sample REST API call illustrates how an MDM can use the Microsoft Graph API to report compliance status of a managed device.

Note

This API is only applicable for approved MDM apps on Windows devices.

Sample Graph API Request:

PATCH https://graph.windows.net/contoso.com/devices/db7ab579-3759-4492-a03f-655ca7f52ae1?api-version=beta HTTP/1.1
Authorization: Bearer eyJ0eXAiO.........
Accept: application/json
Content-Type: application/json
{  "isManaged":true,
   "isCompliant":true
}

Where:

  • contoso.com - This value is the name of the Microsoft Entra tenant to whose directory the device has been joined.
  • db7ab579-3759-4492-a03f-655ca7f52ae1 - This value is the device identifier for the device whose compliance information is being reported to Microsoft Entra ID.
  • eyJ0eXAiO......... - This value is the bearer access token issued by Microsoft Entra ID to the MDM that authorizes the MDM to call the Microsoft Graph API. The access token is placed in the HTTP authorization header of the request.
  • isManaged and isCompliant - These Boolean attributes indicates compliance status.
  • api-version - Use this parameter to specify which version of the graph API is being requested.

Response:

  • Success - HTTP 204 with No Content.
  • Failure/Error - HTTP 404 Not Found. This error may be returned if the specified device or tenant can't be found.

Data loss during unenrollment from Microsoft Entra join

When a user is enrolled into MDM through Microsoft Entra join and then disconnects the enrollment, there's no warning that the user will lose Windows Information Protection (WIP) data. The disconnection message doesn't indicate the loss of WIP data.
