Integrate your on-premises directories with Azure Active Directory
https://docs.microsoft.com/en-us/azure/active-directory/connect/active-directory-aadconnect
Azure AD Connect will integrate your on-premises directories with Azure Active Directory. This allows you to provide a common identity for your users for Office 365, Azure, and SaaS applications integrated with Azure AD. This topic will guide you through the planning, deployment, and operation steps. It is a collection of links to the topics related to this area.
Why use Azure AD Connect
Integrating your on-premises directories with Azure AD makes your users more productive by providing a common identity for accessing both cloud and on-premises resources. Users and organizations can take advantage of the following:
- Users can use a single identity to access on-premises applications and cloud services such as Office 365.
- Single tool to provide an easy deployment experience for synchronization and sign-in.
- Provides the newest capabilities for your scenarios. Azure AD Connect replaces older versions of identity integration tools such as DirSync and Azure AD Sync. For more information, see Hybrid Identity directory integration tools comparison.
How Azure AD Connect works
Azure Active Directory Connect is made up of three primary components: the synchronization services, the optional Active Directory Federation Services component, and the monitoring component named Azure AD Connect Health.
- Synchronization - This component is responsible for creating users, groups, and other objects. It is also responsible for making sure identity information for your on-premises users and groups is matching the cloud.
- AD FS - Federation is an optional part of Azure AD Connect and can be used to configure a hybrid environment using an on-premises AD FS infrastructure. This can be used by organizations to address complex deployments, such as domain join SSO, enforcement of AD sign-in policy, and smart card or 3rd party MFA.
- Health Monitoring - Azure AD Connect Health can provide robust monitoring and provide a central location in the Azure portal to view this activity. For additional information, see Azure Active Directory Connect Health.

You also want to prepare for operational concerns. You might want to have a stand-by server so you easily can fall over if there is a disaster. If you plan to make frequent configuration changes, you should plan for a staging mode server.

Configure sync features
Azure AD Connect comes with several features you can optionally turn on or are enabled by default. Some features might sometimes require more configuration in certain scenarios and topologies.
Filtering is used when you want to limit which objects are synchronized to Azure AD. By default all users, contacts, groups, and Windows 10 computers are synchronized. You can change the filtering based on domains, OUs, or attributes.
Password synchronization synchronizes the password hash in Active Directory to Azure AD. The end-user can use the same password on-premises and in the cloud but only manage it in one location. Since it uses your on-premises Active Directory as the authority, you can also use your own password policy.
Password writeback will allow your users to change and reset their passwords in the cloud and have your on-premises password policy applied.
Device writeback will allow a device registered in Azure AD to be written back to on-premises Active Directory so it can be used for conditional access.
The prevent accidental deletes feature is turned on by default and protects your cloud directory from numerous deletes at the same time. By default it allows 500 deletes per run. You can change this setting depending on your organization size.
Automatic upgrade is enabled by default for express settings installations and ensures your Azure AD Connect is always up to date with the latest release.

Customize Azure AD Connect sync
Azure AD Connect sync comes with a default configuration that is intended to work for most customers and topologies. But there are always situations where the default configuration does not work and must be adjusted. It is supported to make changes as documented in this section and linked topics.
If you have not worked with a synchronization topology before you want to start to understand the basics and the terms used as described in the technical concepts. Azure AD Connect is the evolution of MIIS2003, ILM2007, and FIM2010. Even if some things are identical, a lot has changed as well.
The default configuration assumes there might be more than one forest in the configuration. In those topologies a user object might be represented as a contact in another forest. The user might also have a linked mailbox in another resource forest. The behavior of the default configuration is described in users and contacts.
The configuration model in sync is called declarative provisioning. The advanced attribute flows are using functions to express attribute transformations. You can see and examine the entire configuration using tools which comes with Azure AD Connect. If you need to make configuration changes, make sure you follow the best practices so it is easier to adopt new releases.

Configure federation features
Azure AD Connect provides several features that simplify federating with Azure AD using AD FS and managing your federation trust. Azure AD Connect supports AD FS on Windows Server 2012R2 or later.
Update SSL certificate of AD FS farm even if you are not using Azure AD Connect to manage your federation trust.
Add an AD FS server to your farm to expand the farm as required.
Repair the trust with Azure AD in a few simple clicks.
ADFS can be configured to support multiple domains. For example you might have multiple top domains you need to use for federation.
if your ADFS server has not been configured to automatically update certificates from Azure AD or if you use a non-ADFS solution, then you will be notified when you have to update certificates.
