Azure Active Directory (Azure AD) is a multi-tenant cloud-based directory and identity management service. Devices in Azure AD can be managed using Mobile Device Management (MDM) tools like Microsoft Intune. Businesses can plan and implement device join or hybrid join to Azure AD as part of their security and mobility strategies.
Azure AD Device Join and Hybrid Azure AD Join are two methods to establish a trusted relationship between enterprise-owned and -managed devices and Azure AD. Both offer unique capabilities and benefits. Determining which method to use largely depends on your organizational requirements and existing IT infrastructure.
A. Azure AD Device Join:
This method signifies a device registered only with Azure AD (cloud-only registration). This type is ideal for organizations that have resources in Azure AD and do not require on-premises resources.
B. Hybrid Azure AD Join:
This method signifies a device registered with Azure AD and on-premises Active Directory (dual registration). This type is typically used by organizations that have resources spanning across on-premises and cloud environments.
II. Planning Azure AD Device Join
During the planning phase for Azure AD Device Join, organizations should consider the following aspects:
- Determine the scope of deployment. This includes understanding the number of devices affected, the device platforms involved, and user roles.
- Set up Azure AD and Windows Autopilot, ensuring you have sufficient licenses for each.
- Choose the appropriate device enrollment method, which could be Microsoft Intune, Windows Autopilot, or Windows OOBE.
- Prepare the necessary network requirements. This involves setting the right DNS settings, firewall configurations, and ensuring adequate network capacity.
III. Implementing Azure AD Device Join
Implementing Azure AD Device Join involves the following steps:
- Setting up Azure AD: Ensure that your organization has a valid Azure Subscription and Azure AD setup.
- Registering Your Devices: Register your devices with Azure AD using one of two methods.
- From Settings, access Accounts > Access work or school > Connect > Join this device to Azure Active Directory.
- During Windows OOBE setup, select Set up for an organization, then sign in with a work or school account.
- Configuring MDM automatic enrollment: This allows for device management using Intune.
IV. Planning Hybrid Azure AD Join
When planning for Hybrid Azure AD Join, organizations should:
- Identify the devices needing to join using OS versioning and edition.
- Understand any prerequisites, like AD FS or PHS for federation, and Azure AD Connect for synchronization.
- Plan for any network changes necessary, including network ports and URLs.
V. Implementing Hybrid Azure AD Join
The following are the steps to implement Hybrid Azure AD Join:
- Set up federation with AD FS or Password Hash Sync with Seamless SSO.
- Install and configure Azure AD Connect across your on-premises environment.
- Set up automatic device registration.
Hybrid Azure AD Join and Azure AD Device Join can be powerful tools when managing your organization’s devices. Choosing which method to use, and how to implement it, depends on your unique business needs and technical infrastructure. Understanding the above points can help in taking the most beneficial decision pertaining to MS-101 Microsoft 365 Mobility and Security.
