Even although quite a lot of the performance of area controllers may be moved to the cloud, most organizations that use Active Directory want a hybrid infrastructure that provides customers entry to cloud assets (like OneDrive and Microsoft 365) by way of Azure Active Directory in addition to on-premises file shares, printers and purposes that also want native credentials.
Over the years, Microsoft has had a number of instruments for managing hybrid identification and syncing cloud and on-premises customers and teams.
SEE: Explore TechRepublic’s hybrid cloud cheat sheet.
Microsoft Identity Manager, which changed Forefront Identity Manager, is supported till January 9, 2029, however its Azure AD Connector is deprecated. Azure AD Multi-Factor Authentication Server can also be deprecated and can cease dealing with MFA requests after September 30, 2024. If you’re nonetheless utilizing these instruments, you have to to maneuver to a more moderen choice.

Azure AD Connect and its limitations
Azure AD Connect changed the older DirSync and Azure AD Sync choices for syncing customers, teams and different listing objects to Azure AD. It helps:
- Password hash synchronization: Syncing a hash of every person’s AD password into Azure AD.
- Pass-through authentication: Sending customers to Azure AD to sign up after which validating towards AD, to allow them to use the identical password within the cloud and for native assets while not having to arrange federation.
- Active Directory Federation Services use.
But, Azure AD Connect requires establishing and sustaining a server in your community, and a number of the necessities for operating it don’t work for each group, particularly if in case you have a number of AD “forests,” which makes working with Azure AD sophisticated.
“To use it, you need to be in a connected forest; you need to have installed a database,” stated Joseph Dadzie, a director within the Microsoft identification workforce. “That’s costly to handle and deploy.
“We started getting feedback from a lot of customers around the cost of a deploying AD Connect sync and of maintaining it, and some feature gaps around if you are in a disconnected forest or you are in an organization where you are trying to do an M&A. So, we set out to look at ways to simplify it.”
Cloud sync goals to interchange Azure AD Connect for cloud
The result’s Azure AD Connect cloud sync, which began out as a software for bringing identities from a number of disconnected AD forests right into a single Azure AD tenant.
It nonetheless does that, nevertheless it’s now a light-weight different to AD Connect that doesn’t have fairly as many options however is way quicker to arrange and requires fewer assets. This is as a result of cloud sync strikes a lot of the configuration into the cloud, needing solely provisioning brokers.
“When you look at AD Connect, almost all the configuration is done in the on-prem world, and it’s stored in that local server,” stated Dadzie. “For cloud sync, the concept is to change the configuration to be cloud based mostly and have a really light-weight agent within the buyer’s surroundings in order that it’s simple to deploy.
“It takes about 10 megabytes, so you can have multiple of these working together for high availability solutions; something that’s more difficult to do if you have a full Connect sync capability.”
That excessive availability is especially helpful when you’re utilizing Microsoft’s advisable password hash synchronization.
The way forward for cloud sync
Cloud sync can deal with teams with as much as 50,000 members, nevertheless it doesn’t cowl every part you are able to do with AD Connect sync but, Dadzie informed us.
“If you’ve done a lot of customizations on attributes in your AD and you still use Exchange on-prem, there’s still some delta in the capabilities,” stated Dadzie. “In the longer term, we will want to have it be the full replacement; we are not there yet.”
Currently, it may possibly’t hook up with LDAP directories and doesn’t but have help for gadget objects, simply customers, teams and contacts. There are superior customization and filtering choices that aren’t obtainable, and cloud sync can’t deal with Exchange hybrid writeback, so you may’t use it for Exchange hybrid migrations.
Federation is supported however not Azure AD Domain Services or Pass Through Authentication, not less than for disconnected forests. That’s one thing the AD Connect workforce is engaged on, Dadzie stated, and writeback for safety teams can also be in growth.
“Over the past year, we added the self-service password writeback scenarios,” stated Dadzie.
Device writeback can also be underneath growth, as a result of “almost any deployment starts with getting some of the users from on-prem to the cloud,” Dadzie notes. It’s barely complicated as a result of each Azure AS and Windows Hello For Business have providers named Cloud Kerberos belief, which do various things, however Microsoft tells us the naming and documentation ought to turn into clearer in future.
The cloud sync workforce can also be taking a look at alternate options to writeback.
“If you have an on-prem app and you have a cloud user who needs access to it, how do you give that user access without having an account in the on-prem AD,” stated Dadzie. “We’re looking at what we might do in that space: Is there a way to have some of the secrets go down so that you can have the user credentials, where the user gets access to on-prem without having to have the user object in there?”
That’s nonetheless within the early levels, however there are common updates to cloud sync performance.
“Every quarter to six months, we update and add new capabilities,” stated Dadzie. “We’re on a mission to chip away at the reasons why someone might still want to use the full AD Connect sync. We’re on a mission to keep adding to cloud sync to the point that we eventually replace AD Connect sync, but we are not there yet.”
Choosing between Azure AD Connect and cloud sync
There’s no urgency about transferring to cloud sync when you want an AD Connect sync function, however there are some situations the place cloud sync is already the higher selection, in addition to much less demanding.
“It works well for organizations that are not as complicated or don’t have a lot of objects; if they have less than 150K objects in their directory, then it’s easier to start off using cloud sync,” stated Dadzie.
There’s a wizard within the Microsoft 365 admin heart that walks you thru selecting the best identification sync choice in addition to a step-by-step migration information if you wish to transfer from Azure AD Connect sync to cloud sync.
How advanced that migration will probably be depends upon how advanced your AD surroundings is: “The more complex the environment is, then a more phased approach works,” Dazie stated. But in case your wants are much less advanced and also you’re beginning out with hybrid identification, he suggests beginning with cloud sync for simplicity (Figure A).

In reality, a giant a part of the attraction of cloud sync is that it’s designed to be a lot simpler to get began with.
“In Connect sync, you have to do all the Schema Mapping yourself, whereas in cloud sync we try to autodiscover them for you, so you don’t have to hunt around and to make it easy for you to configure those,” stated Dadzie. “The main philosophy we are trying to get with cloud sync is to make it super, super easy, so customers don’t have to think through these things.”
