Future of adfs

One question I am continually asked by my readers and my customers in my work life concerns authentication and Office Well, to be honest, this question cannot generally be answered! In this article, I will write about both ways you can go with. Perhaps it will help you to find the right solution in your case or how you want to work in the future. Best of all, if you are working as an IT consultant, you will be able to choose the right solution for your projects.

In another article in my blog, I have described how ADFS has to be configured and how it can be personalized. Employees can use their company workstation or any private device. If they are using a company workstation, they will have to log in with the company domain credentials to the workstation. If they use a private computer and want to access the company environment, they will have to first authenticate with the company environment through the ADFS and after that, they will be able to use all features.

The on-premises and the cloud site have configured a federation between each other that depends on the identity model. There are different ways to deal with them. However, from my point of view, one of the best ways is to use directory sync with federated identity. This is shown in the image above. If the user now tries to connect to the cloud services outside of the company, he goes to the Office portal and enters his company credentials.

If all is correct, the user will be able to log in. This principle works not just for authentication between our on-premises environment and Office or Azure, it also works for many third-party cloud services such as AWS, G Suite, and Salesforce. One of the things we have to think about with this solution is that it is highly recommended that we build the ADFS environment on-premises and that we do it redundantly.

Let us first have a look at how the authentication by using Azure AD pass-through works:. If the user is not signed in, he will be redirected to the Azure AD sign-in page where he will need to enter his username and password.

The on-premises Authentication Agent retrieves the username and encrypted password from the queue. The agent decrypts the password using its private key and validates the information with Active Directory.

Azure AD Federation Fundamentals

If all the information is correct, Azure AD evaluates the response and responds to the user as appropriate. If the user sign-in is successful, the user can access the application. Authentication with Azure AD Pass-through is constantly being improved by Microsoft and receives regular feature updates.

But I can recommend it only for use with Microsoft cloud services authentication. After the configuration is made, we can connect to our Azure Active Directory and after browsing to Azure AD Connectwe see, that pass-through is enabled.

The agents for the authentication service can be installed on each server that has access to the Active Directory and its catalog and is available from the cloud side.

Both solutions are good. That is why I cannot make the recommendation on which of the two options you should use. However, this was never the goal of this article.

It shows two ways how authentication can be handled using Microsoft tools. At the moment, I recommend to my customers that if they are using only Microsoft services, authentication with AD Pass-through is a good solution. Going in the other direction from pass-through to ADFS is also possible, but it takes more time.

If something goes wrong in the network and none of the AuthN agents are available, nobody can log in anymore. If you need to set up a low-cost authentication for Microsoft cloud services in your project, this can be a solution to what might be a serious problem.

On the surface, from reading a few whitepapers PDFarticles and books on the subject, this seems like the perfect solution -- especially for a company that has an internal web site that exposes some level of functionality to external users and partners as well or plans to in the future.

But it sounds almost too perfect.

And most of the information I have comes from Microsoft themselves. As more applications are moved to the cloud and to online services you will see ADFS and other federated identity technologies increase in usage. Organizations with investments in Active Directory will likely move to this solution due the low cost of ownership. How likely is it that a partner would be willing to setup an STS if we wanted someone else to provide authentication for their company as a trusted issuer?

Also in NZ, we have an igovt login which provides one login to all governments departments and this is a possible candidate for "use an existing login" rather than creating a company specific one. Larger companies who want to allow external access to their applications would far rather implement an STS than provision external users in their identity repository.

Ask Question.In Aprilwe made Windows Azure Active Directory generally available to businesses and cloud application developers for use in production environments.

The end result will be a fully featured solution to meet your cloud identity needs. Access Control Service ACS makes it easier for cloud application developers to integrate their applications with popular social identity providers and with on-premises ADFS without requiring them to write custom code per identity provider. The rules engine of ACS v2 enables applications to transform claims in the incoming tokens to consistent claims understood by the application. ACS v2 however does not provide traditional directory constructs like users and groups, which limits its value to businesses that want to leverage a cloud identity system.

Also, the model of federating on-premises ADFS with individual ACS v2 namespaces of various cloud applications may require businesses to maintain more than one federation relationship. Windows Azure Active Directory is an identity service offering with rich identity, federation and directory capabilities.

Organizations use Windows Azure AD to manage their identities and access control for their software-as-a-service applications. Large organizations are able to extend their existing on-premises AD authentication and authorization to application running in the cloud. Customers can also use Windows Azure Active Directory to connect to and manage other 3rd party online services. Because the two services share several features in common, if you are embarking on new development we would encourage you to look at Windows Azure AD as your first alternative followed by ACS v2.

What's New. Microsoft Store.There are a number of different components that must all work together to provide Active Directory federation for Office The first requirement is that you must have an Active Directory with one or more domain controllers in place.

The only real requirement for the Active Directory is that all domain controllers must be running a minimum of Windows Server For example, if you use the name adfs. It is common for organizations to use maintain separate internal and external domain names. A best practice was to have your internal Active Directory domain name have a. With Officethe user principle name UPN suffix must match your external domain name, which you have registered and verified within Office In these situations, it is necessary to add a user principle name suffix to the AD.

Users must be authenticated using this external domain name. This is an important point and could pose challenges for larger organizations, especially those with existing certificate infrastructures. To add a UPN suffix to your domain, see this article. Another important point to consider is whether you want to use multiple UPNs. ADFS makes extensive use of digital certificates.

It is possible to configure a Windows server to act as an Enterprise Certificate Authority, assuming all client computers trust the certificate authority. These certs will be trusted by your clients, mobile, devices, and the whole process is made much easier.

The reason why SSL certificates are required is because the client computer must be able to communicate with the Web service, the resource partner, and the account partner. The most important thing to remember about your SSL certificate is that the subject name must match the name used within the ADFS configuration.

Misconfigured subject names are a common problem that administrators tend to have when setting up ADFS. Office requires you to download and install the 2. When you get ready to download ADFS 2.

Microsoft Office contains applications such as Exchange and SharePoint that are usually considered to be mission critical. This brings us to the main weaknesses of ADFS. Consider, for example, a small office which currently hosts 2 domain controllers on-premises.

If they set up ADFS, and lose power in their office, nobody will be able to access the Office services, because the domain controllers are offline and unable to authenticate users. For all the frustrations that users have with BPOS passwords, there is one benefit, in that if your on-premises infrastructure fails, users could continue working remotely and access Exchange and SharePoint. When you introduce ADFS, you create a dependency on your on-premises infrastructure being available and accessible.

Another thing to note is that it is possible to disable ADFS. The proper way to provide scalability and fault tolerance is to create an ADFS farm.This talk is for developers and Vittorio makes that clear in a very humorous way from the beginning.

To help understand the problem, we need to understand what types of identity systems currently exist. Microsoft cares about all of these various types of providers. For some, a solution exists today; for others, Microsoft is working on a solution.

According to Vittorio, they are committed to addressing all of them. The importance of strong fundamentals…. Vittorio discussed each of these in detail, but they are really self-explanatory.

We all know how important security is. First, the solution must use open protocols. You must be able to find detailed information about the solution for proper implementation. Next, it must have great management and lifecycle features. Finally, it must have a great user experience. How do we get there? On-premises Active Directory has been available since and is the most widely used business identity solution.

What happens when you move your app to the cloud? For instance, what groups are they a member of or who is their manager. Also, AD FS has serious scale limitations. Each third-party must maintain their own AD FS infrastructure and you must connect to each one individually. How do we solve these problems? Enter Azure Active Directory. Microsoft faced the very same problems when designing Office It uses open authentication and authorization standards.

Azure AD Fundamentals Microsoft has built 30 data centers around the world, 22 in production and 8 announced. This is more than the next 2 competitors combined.

I heard this stat a number of times at Build. Azure AD provided intelligent, ever evolving security.

If a user logs in from Chicago at pm and the same user tries to authenticate from Hong Kong at pm, then Azure AD will block the second authentication request. Microsoft also has a team that watches black markets for identities that are being sold.

If you lose your identity, Microsoft will notify you that it has been compromised. Very cool! Azure AD also provides geo replication and disaster recovery natively. In addition, it provides data sovereignty capabilities for regions such as Germany where data privacy laws are very strict.

Finally, Microsoft offers a free tier which makes the solution ultra affordable for every use case. This solution allows you to white label an authentication solution. It runs on the same infrastructure as Azure AD, which is scalable, secure, provides Multi-factor Authentication support, and has open protocol integration.Previously I have been installing high available ADFS farms to almost every customer that had more than few users and wanted single sign on to Office Today, Microsoft has good documentation how to choose authentication for your use.

My recommendation is always use Password Hash Sync and incorporate it with Pass-through Authentication if strict enforcement of local AD policies is needed. Doing this enables more identity protection features f. In most of the customer cases I have worked in, ADFS was built because of Office and then more applications got added to it. Using one common identity and authentication source increases security as a user account is more probably closed when employment ends.

In most cases you could move those applications to use Azure AD as their authentication source.

Actual application registration takes no more than two minutes if you have all the details available. The name is displayed in My Apps portal so choose wisely. Otherwise you must assign the application to an individual user or group. These are something that you find from existing ADFS federation. In this case, I get a full list of claims provided by federation. This could also be used in complex scenarios for debugging issuing rules. Single Sign-on from any device that is joined to Azure AD.

This also applies to mobile devices if they are Azure AD joined. Single point of application access and control. You can use Azure AD not only to define who can access which Office application but also to specify what 3rd party SaaS applications end user can access.

End user will have My Apps portal for all the applications they have access to. Conditional Access polices can also be defined to secure 3rd party SaaS applications.

This is something really useful. You can specify that for example Salesforce is usable from trusted devices without any additional authentication but using it from un-managed devices requires multi factor authentication.

You can use built-in Azure AD functionality to enable end users to change or reset their passwords. This requires enabling password writeback to the onprem AD. You can get rid of all the ADFS servers and infrastructure. This might be four servers and load balancer. Best practice however suggests that servers hosting these services should be treated as tier 0 servers. There are some limitations if not using onprem ADFS that you need to understand.

For example you could not use certificates for logging in to services. If your solution requires this, you must use ADFS. If you need to transform claims or create federation chains, ADFS is the way to go.

Some of the claims are restricted and you could not use Azure AD to send those. If those are needed, ADFS must be used.This is understandable. These days, IT is increasingly expected to get the job done, and more quickly with fewer resources.

ADFS needs consistent management, maintenance and support, and if there are issues or it goes down, we have to take care of it.

Bringing in OneLogin has been a big deal for systems integration. Not only did this reduce risk, it saved the firm time and money as well. This same construction materials firm used an internal ADFS setup to connect four cloud-based apps. If there are any issues or support needed, they take care of it. Compare that to the cost of resources, commitments and support hours [for ADFS]; and you have to do constant maintenance patching.

And we moved on to our next project. Thomas Bayens is responsible for customer marketing at OneLogin.
