Contributed by:CIntroductionThis document describes how to integrate a Citrix environment with the Windows 10 Azure AD feature. Windows 10 introduced Azure AD, which is a new domain join model where roaming laptops can be joined to a corporate domain over the Internet for the purposes of management and single sign-on.The example deployment in this document describes a system where IT provides new users with a corporate email address and enrollment code for their personal Windows 10 laptops. Users access this code through the System About Join Azure AD option in the Settings panel.After the laptop is enrolled, the Microsoft Edge web browser automatically signs on to company web sites and Citrix published applications through the Azure SaaS applications web page, with other Azure applications such as Office 365.ArchitectureThis architecture replicates a traditional company network completely within Azure, integrating with modern cloud technologies such as Azure AD and Office 365. End users are all considered remote workers, with no concept of being on an office intranet.The model can be applied to companies with existing on premises systems, because the Azure AD Connect Synchronization can bridge to Azure over the Internet.Secure connections and single sign-on, which would traditionally have been firewalled-LAN and Kerberos/NTLM authentication, are replaced in this architecture by TLS connections to Azure and SAML.
New services are built as Azure applications joined to Azure AD. Existing applications that require Active Directory (such as a SQL Server database) can be run using a standard Active Directory Server VM in the IAAS portion of the Azure Cloud Service.When a user launches a traditional application, they are accessed using Citrix Virtual Apps and Desktops published applications. The different types of applications are collated through the user’s Azure Applications page, using the Microsoft Edge Single sign-on features. Microsoft also supplies Android and iOS apps that can enumerate and launch Azure applications.Create a DNS zoneAzure AD requires that the administrator has registered a public DNS address and controls the delegation zone for the domain name suffix. To do this, the administrator can use the Azure DNS zone feature.This example uses the DNS zone name citrixsamldemo.net.The console shows the names of the Azure DNS name servers. These should be referenced in the DNS registrar’s NS entries for the zone (for example, citrixsamldemo.net. NS n1-01.azure-dns.com)When adding references to VMs running in Azure, it is easiest to use a CNAME pointer to the Azure-managed DNS record for the VM.
At the SQL Server, use the Start menu to search for and launch the SQL Server Installation Center. See for more information.Using the SQL Server Installation CenterUse the following steps to see all installed instances of SQL and the information about that instance. On the left side of the SQL Server Installation Center, choose Tools. On the right side, choose Installed SQL Server features discovery report. Sql server 2012 versions list.
If the IP address of the VM changes, you will not need to manually update the DNS zone file.Both internal and external DNS address suffixes will match for this deployment. The domain is citrixsamldemo.net, and uses a split DNS (10.0.0. internally).Add an “fs.citrixsamldemo.net” entry that references the Web Application Proxy server. This is the Federation Service for this zone.Create a Cloud ServiceThis example configures a Citrix environment, including an AD environment with an ADFS server running in Azure. A Cloud Service is created, named “citrixsamldemo.”Create Windows virtual machinesCreate five Windows VMs running in the Cloud Service:.
Domain controller (domaincontrol). Azure Connect ADFS server (adfs). ADFS web access proxy (Web Application Proxy, not domain joined).
Citrix Virtual Desktops Delivery Controller (ddc). Citrix Virtual Desktops Virtual Delivery Agent (VDA)Domain Controller. Add the DNS Server and Active Directory Domain Services roles to create a standard Active Directory deployment (in this example, citrixsamldemo. After domain promotion completes, add the Active Directory Certification Services role. Create a normal user account for testing (for example, [email protected]).
Since this server will be running internal DNS, all servers should refer to this server for DNS resolution. This can be done through the Azure DNS settings page. (For more information, see the Appendix in this document.)ADFS controller and Web Application Proxy server.Join the ADFS server to the citrixsamldemo domain.

To expand on @jonathan-mas answer,This can be done using command line only (as of Dec 2017). I don't prefer the Powershell approach (limited portability), I prefer as it is more direct in answering this question.Create a listener for your HTTP traffic (e.g. This can be done using Azure portal or CLI.Create a listener for your HTTPS traffic (e.g. This can be done in Azure portal or CLI.Create a redirect configuration:az network application-gateway redirect-config create -gateway-name AppGateway -g RSgroupAppGateway -n Redirect-Site-toHTTPS -type Permanent -include-path true -include-query-string true -target-listener FE-HTTPS-443-Site.

This is now supported by the Azure Application Gateway product without any additional tools or services.
Tutorial: Create an application gateway with a web application firewall using the Azure portal. 4/16/2019. 8 minutes to read. Contributors.In this articleThis tutorial shows you how to use the Azure portal to create an with a (WAF). The WAF uses rules to protect your application. These rules include protection against attacks such as SQL injection, cross-site scripting attacks, and session hijacks. After creating the application gateway, you test it to make sure it's working correctly.
With Azure Application Gateway, you direct your application web traffic to specific resources by assigning listeners to ports, creating rules, and adding resources to a backend pool. For the sake of simplicity, this tutorial uses a simple setup with a public front-end IP, a basic listener to host a single site on this application gateway, two virtual machines used for the backend pool, and a basic request routing rule.In this tutorial, you learn how to.
ADFS is an STS. Azure AD is an IAM (Identity and Access Management).
Youcan do SO much great stuff with Azure AD. Things like dynamic groups toautomatically assign users to a SaaS apps based on attributes of thatuser. Self Service group management means you can designate this groupapproval to a business unit so they can approve who has access to theapps that they own. We also can do provisioning and de-provisioning tosome of these SaaS Apps as well.
Not to mention all the securitybenefits of being on Azure AD. If you are looking at them purely as SAML providers they are roughly equivalent. But there is more to federation than just SAML. There are other protocols and profiles that AAD can support that ADFS cannot.
Remember that ADFS is a shipped product, it ships with the version of Windows and its capabilities stay roughly the same for its lifetime. It might get an upgrade in a big service pack.
So ADFS on Server 2012 R2 has pretty much the same capabilities for the last 5 years. The new ADFS on 2016 has more, but it is subject to the same static life.
Azure AD is constantly upgrading.So strategically, if you don't mind putting your eggs in Microsoft's basket, AAD seems the better choice from that standpoint.However, you have to measure your organization's willingness to rely on a cloud service versus on premises servers and network infrastructure you control.Beyond that, AAD does much more than federation. You can use it to present a portal to your users, to secure groups of apps, to run analytics on your authentications for security, it can serve as an authentication backbone between other tenants, clients and consumers.So you asked a complicated question, but the answer is probably AAD unless you aren't comfortable with the lack of control on the cloud service. One big difference I've seen, in terms of sso and saml is that ADFS has greater support for 'claims language' than AAD. AAD offers limited capabilities or whatever is present in GUI. For example, I do not see any regex support for claims when using AAD. Its very probably that you won't need them but is worth mentioning.In general, for a particular function, an on-prem system has greater flexibility, but it will not get any updates as fast as a cloud one, and does not integrate with other services that are deployed in cloud (like in the AAD case). Hi Neil,In my opinion this is not a newby question.
Its a question allot of IT admins are struggling with.Offcourse ADFS is a STS and AzureAD a IAM but this doesn't answer the question when to use what. When I am wrong please notice me on this people but my point of view is that the best solution is very dependent on the type of clients the users are using.AzureAD joined device Windows 10 (build 10551 or newer) work great when we wan't to achieve true SSO.
With true SSO I state that the authentication proces is done on sign on of the desktop and isn't needed in any other way anymore when browsing to webbased applications.When using domain joined Windows 7 or 8.x you need Internet Explorer and Microsoft ADFS when to achieve this user experience.So the best solution to use as STS is also depended on other components (like the Windows Clients) in your environment.The most important difference between ADFS and AzureAD looking at the STS component is where the authentication proces takes place. With ADFS this is on-premise, with AzureAD this is in the cloud.Also take a look at this great article of Pierre Audonnet.Regards,Mikkie. Hello Neil,All of this feedback is fantastic. I would also like to add a few more things to think about.
AD FS will authenticate your cloud or synchronized identities on premises. Many large organizations prefer this federated model because they are authenticating 'in-house'. With a synchronized solution, Microsoft would be authentication your users. You synchronize your users using AAD Connect and also enable password synchronization. This would mean that we would send your password hashes to your AAD.
This is, of course, a very secure solution given that the hashes are hashed and salted, and then some. Nevertheless, you get the point. This being said, smaller organization are choosing AAD Connect Pass-Through-Authentication over ADFS for simplicity sake. Diablo 3 conquests season 12. PTA can authenticate your users on premises without the IT overhead of a complex ADFS farm.
If your cloud application are Office 365 and some Azure Gallery apps, PTA may be a viable alternative. Of course, AD FS is a robust authentication solution with a large portfolio of authentication mechanisms such as FBA/CBA, Claims, oAuth, etc. I hope this helps.
Azure Application Gateway Limits
We have used PTA mode for a while (started with preview even), until one day it just stopped working. Switched to Password Synchronization and it worked. Haven't figured out what happened with PTA (it was after usual Windows updates, so maybe some fix affected something). But even with PTA working you have to keep server with AD Connect running 24/7, as without it logins would be impossible.
This server becomes a critical breaking point of your cloud services.Also, this was an old reply, but i will mention anyway. One can still have SSO on domain joined Windows 7 PCs, using Seamless Single Sign On option of AD Connect.
Update : The POC of this article is available on.I have a scenario perfect for a Layer-7 Load Balancer / Reverse Proxy:. Multiple web server clusters to be routed under one URL hierarchy (one domain name). Redirect HTTP traffic to the same URL on HTTPS. Have reverse proxy performing SSL termination (or SSL offloading), i.e. Accepting HTTPS but routing to underlying servers using HTTPOn paper, can do all of those.
Let’s fine out in practice. Azure Application Gateway ConceptsFrom:Application Gateway is a layer-7 load balancer. It provides failover, performance-routing HTTP requests between different servers, whether they are on the cloud or on-premises. Application Gateway provides many Application Delivery Controller (ADC) features including HTTP load balancing, cookie-based session affinity, Secure Sockets Layer (SSL) offload, custom health probes, support for multi-site, and many others.Before we get into the meat of it, there are a Application Gateway uses and we need to understand:. Back-end server pool: The list of IP addresses of the back-end servers.
The IP addresses listed should either belong to the virtual network subnet or should be a public IP/VIP. Back-end server pool settings: Every pool has settings like port, protocol, and cookie-based affinity. These settings are tied to a pool and are applied to all servers within the pool. Front-end port: This port is the public port that is opened on the application gateway.
Traffic hits this port, and then gets redirected to one of the back-end servers. Listener: The listener has a front-end port, a protocol (Http or Https, these values are case-sensitive), and the SSL certificate name (if configuring SSL offload). Rule: The rule binds the listener, the back-end server pool and defines which back-end server pool the traffic should be directed to when it hits a particular listener.On top of those, we should probably add probes that are associated to a back-end pool to determine its health. Proof of ConceptAs a proof of concept, we’re going to implement the following:We use Windows Virtual Machine Scale Sets (VMSS) for back-end servers.In a production setup, we would go for exposing the port 443 on the web, but for a POC, this should be sufficient.As of this writing, there are no feature to allow automatic redirection from port 80 to port 443. Usually, for public web site, we want to redirect users to HTTPS. This could be achieve by having one of the VM scale set implementing the redirection and routing HTTP traffic to it.
ARM TemplateWe’ve published the ARM template.First, let’s look at the.The template is split within 4 files:. azuredeploy.json, the master ARM template. It simply references the others and passes parameters around. network.json, responsible for the virtual network and Network Security Groups. app-gateway.json, responsible for the Azure Application Gateway and its public IP. vmss.json, responsible for VM scale set, a public IP and a public load balancer; this template is invoked 3 times with 3 different set of parameters to create the 3 VM scale setsWe’ve configured the VMSS to have public IPs.
It is quite typical to want to connect directly to a back-end servers while testing. We also optionally open the VMSS to RDP traffic; this is controlled by the ARM template’s parameter RDP Rule ( Allow, Deny). Template parametersHere are the following ARM template parameters. This has been really helpful, but I think it is worth noting the “Override Backend Path” feature that is available now which allows the /a/ route to be / when it gets to the server.So for instance, using the Resource Manager, if I want my /a/ route to actually hit the default / route on the server it is pointed to, I would go to my Backend HTTP Settings and fill in the “Override Backend Path” with / then in the Rule I was using set the HTTP Setting for that path to be the HTTP Settings I made the override on. So the functionality is at least there if it is needed. This would make “mydomain.com/a/” still look like “mydomain.com/a/” but route to “mydomain.com” behind the scenes. Yes definitely!
It gets a little confusing because in the GUI Resource manager it is called “Override Backend Path” but in the template you are referencing it is just called “path” as part of the BackendHttpSettings object. It’s located atbackendHttpSettingsCollection:properties:pathHowever, I’d like to point out about it is that when overriding the backend path. I thought I could use it like “mydomain.com/a” without the trailing “/” but currently to get the request to be routed properly you have to have the trailing “/” like “mydomain.com/a/” or it won’t go through.
