Frequently asked questions about CMG - Configuration Manager (2023)

Applies to: Configuration Manager (current branch)

This article answers frequently asked questions about Cloud Management Gateway (CMG). For more information seeCMG impressed.

Do I need any certificates?

Yes, at least one, and maybe another, depending on your project.

  • Server authentication certificate: CMG creates an HTTPS service that Internet clients connect to. The service requires server authentication to build a secure channel. For this purpose, you can obtain a certificate from a public provider or issue it from your Public Key Infrastructure (PKI). For more information seeCMG server authentication certificate.

  • Client Authentication Certificate: Depending on your CMG environment and design, you can use PKI certificates to authenticate clients. This authentication method does not support user-facing scenarios, but it does support devices running any supported version of Windows. For more information seeConfigure client authentication for the CMG: PKI certificate.

    When using this client authentication method, you must also export the trusted root chain of the client certificate. You will then use this certificate chain when creating the CMG and CMG connection point.

  • HTTPS enabled management point: Depending on how your site is configured and the client authentication method you choose, you may need to configure Internet-enabled management points to support HTTPS. For more information seeConfigure client authentication for CMG: Enable the management point for HTTPS.

Do I need Azure ExpressRoute?

NO.Azure ExpressRouteallows you to extend your local network to the Microsoft cloud. ExpressRoute or other such VNet connections are not required for CMG. The CMG project enables Internet clients to communicate via Azure with on-premises systems without additional network configuration. For more information seeCMG impressed.

Do I need to maintain or provision an Azure VM?

NONE. The CMG project uses Azure as a Service (PaaS). Using the provisioned subscription, Configuration Manager creates the necessary VMs, storage, and network. Azure secures and updates your virtual machines. You do not need to monitor these VMs. Azure VMs for CMG are not part of your on-premises environment like Infrastructure as a Service (IaaS). CMG is a PaaS service that extends the configuration manager environment to the cloud. For more information seeSecuring PaaS implementations.

As CMG acts as a proxy for customer communications, it does not process, store or retain any customer data. The communication path over the Internet always uses the HTTPS protocol. For added security, configure the management point for HTTPS. Also configure the client site's ability to encrypt storage and status messages. For more information seePlan security: signing and encryption.

How can I ensure service continuity during service updates?

When you scale your CMG to include two or more instances, you automatically benefit from domain updates in Azure. SeeHow to update a cloud service.

I already use IBCM. If I add CMG, how will customers behave?

If you have already implementedonline customer management(IBCM), you can also implement CMG. Users get policies for both services. While browsing the Internet, they randomly select and use one of these Internet services.

Do user accounts need to be in the same Azure AD tenant as the tenant associated with the subscription hosting the CMG cloud service?

No, you can deploy CMG in any subscription that supports Azure cloud services.

To clarify the terms:

  • Azure ADtenantis a summary of user accounts and application registration. A tenant can have several subscriptions.
  • AzureSubscriptionseparates billing, resources and services. It is associated with one tenant.


(Video) SCCM Interview Questions and Answers | Configuration Manager Interview Questions|

For more information seeSubscriptions, licenses, accounts and tenants for Microsoft cloud services.

This question is common in the following scenarios:

  • When you have separate Active Directory and Azure AD test and production environments, but a single centralized Azure hosting subscription.

  • Your use of Azure has grown organically across teams.

If you are using a Resource Manager deployment, you must join the Azure AD tenant associated with the subscription. This connection allows Configuration Manager to authenticate to Azure to create, deploy, and manage the CMG.

If you use Azure AD authentication for users and devices managed through CMG, you must enroll in this Azure AD tenant. For more information about Azure cloud management services, seeConfigure Azure services. After each Azure AD tenant joins, a single CMG can provide Azure AD authentication to multiple tenants, regardless of hosting location.

Example 1: A tenant with multiple subscriptions

User identities, device registrations, and application registrations reside with the same tenant. You can choose the subscription that CMG uses. You can deploy multiple CMG services from one location in separate subscriptions. The site has a one-to-one relationship with the tenant. You decide which subscriptions you want to use for various reasons, such as billing or logical separation.

Example 2: Multiple tenants

In other words, your environment has more than one Azure AD. If you need to support user and device identities in both tenants, you must associate a seat with each tenant. This procedure requires each tenant's administrative account to create application records in that tenant. A single site can then host CMG services for multiple tenants. You can create a CMG in any available subscription in any tenant. Devices that are Azure AD joined or hybrid joined can use CMG.

If the user and device identities are in one tenant, but the CMG subscription is in a different tenant, you must sign up for both tenants' sites. Technically, a client application is not required for a second tenant that only has CMG service. The client application provides user and device authentication only to clients using the CMG service.

How does CMG affect my VPN-connected clients?

Mobile clients that connect to your environment via VPN are often registered as accessible on your intranet. They attempt to connect to local infrastructure such as management points and distribution points. Some users prefer to have these roaming clients managed by cloud services, even if they are connected via VPN.

You can also bind a CMG to a boundary group. This action forces these clients not to use local site systems. For more information seeSet up border groups.

How does the configuration of management points affect internal clients?

To secure sensitive traffic sent by CMG, configure at least one management point to use HTTPS or configure your website to support enhanced HTTP.

Then, when you set up CMG, if you use PKI certificates for HTTPS communication on a CMG-enabled management point, selectOnly allow clients with internetin the management point properties. This setting ensures that internal clients continue to use HTTP management points in your environment.

If you are using Extended HTTP, you do not need to configure this setting. Clients still use HTTP when communicating directly with a CMG-enabled management point. For more information seeImproved HTTP protocol.

What are the differences in client authentication between Azure AD and certificates?

You can use Azure AD or a client authentication certificate for devices to authenticate on the CMG. You can also use tokens issued by the Configuration Manager page for authentication.

If you manage traditional Windows clients with an Active Directory domain-joined identity, they need PKI certificates to secure the communication channel. These clients can include any supported version of Windows. You can use all features supported by CMG, but software distribution is limited to devices only. Install the Configuration Manager client before the device connects to the Internet or use token authentication.

You can also manage clients running Windows 10 or later with a modern identity, hybrid, or cloud-only domain joined to Azure AD. Clients use Azure AD for authentication instead of PKI certificates. Using Azure AD is easier to set up, configure and maintain than more complex PKI systems. You can perform all the same software management and distribution activities for the user. It also provides additional methods to install the client on a remote device.

Microsoft recommends joining devices to Azure AD. Internet devices can use Azure AD for authentication using Configuration Manager. It also enables device and user scenarios regardless of whether the device is online or connected to an internal network.

For more information seeConfigure client authentication.

Should I use a scaled virtual machine pool deployment?

Yes, if your site is version 2107 or later. This is no longer a pre-release feature and is recommended for all users. If you have an existing classic CMG implementation, you canconvert it to a virtual machine benchmark set.

If your site is version 2010 or 2103, the scaled virtual machine pool setup method is a pre-release feature. It is only intended for customers with a Cloud Solution Provider (CSP) subscription.


From version 2203, the ability to deploy CMG ascloud service (classic)is removed. All CMG implementations must usevirtual machine scale set. For more information seeRemoved and deprecated features.

For more information on setting up CMG as a virtual machine benchmark set, seeSchedule a CMG.

Does content-enabled CMG use Azure CDN?

NONE. Azure Content Delivery Network (CDN) is not currently supported. A CDN is a global solution for fast, high-bandwidth content delivery by storing content in strategically located physical nodes around the world. For more information seeWhat is Azure CDN?.

Should I do anything about deprecating Azure AD Graph API and Azure AD Authentication Library (ADAL)?

DOES NOT. You may have seen the following blog post and are wondering how it relates to Configuration Manager:Update your applications to use the Microsoft Authentication Library and the Microsoft Graph API. This post applies to any developed code that uses these authentication libraries. Configuration Manager has used the Microsoft Graph API and the Microsoft Authentication Library (MSAL) in some places for several years. All other components are updated in Configuration Manager version 2107 with the extensionset updates. If you are up to date with the versions of Configuration Manager, you do not need to do anything else.

Some people confuse the information in this blog post with the Azure AD application registrations that Configuration Manager uses for various cloud-related services. These application registrations are principals for cloud-based services that do not directly use these authentication libraries. If the Azure Global Administrator manually created Configuration Manager registrations in Azure AD, they can double-check that these registrations have permissions toMicrosoft diagramAPI. They do not need permissionAzure AD-diagramAPI. For mere information seRegister Azure AD applications manually.
