Azure Application proxy and AD Connect/Pass though authentication - azure

We are using on-prem and Azure cloud separately and planning to make connection between on-prem AD and Azure AD by using Azure AD connect or Pass-though authentication (preview).
My question is, If we use Azure AD connect or pass-though ,will there be any need to use Azure application proxy in any case?
Under what scenario/application integration, both application proxy and Azure AD connect/pass-through will be required?

If we use Azure AD connect or pass-though ,will there be any need to
use Azure application proxy in any case?
By default, there is no need to deploy a proxy for Azure AD connect. It depends on your local network, if your On-prem server(AAD connect installed) can connect to the internet direct, we should not deploy the proxy.
Under what scenario/application integration, both application proxy
and Azure AD connect/pass-through will be required?
This table describes the ports and protocols that are required for communication between the Azure AD Connect server and on-premises AD:
More information about hybrid identity required ports and protocols, please refer to this official article.
If your on-prem network can't open those ports, we need to deploy a proxy for it.

Windows Virtual Desktop why I need an AD sync to Azure AD

why I need a sync from onpremise AD to Azure AD for azure windows virtual desktop? It stands in the requierments but I do not understand the details why.
Regards
Stefan
Windows Virtual desktop is at time not compatible to run in a cloud only environment with Azure Active Directory only.
There are two options supported.
• Local AD synced with AAD connect to Azure AD
If you already are using a local active directory synced with Azure Ad Connect to Azure AD. This is probably your first choice of setup. You will need to add an Azure VPN to connect your LAN to an Azure Network. The WVD hosts need access to a Domain controller. For the best performance and functions, I also recommend setup of a Virtual domain controller in Azure.
• Azure Domain Services
If you have gone cloud only and deprecated your local AD, Azure offer Azure Domain Services. This is an Azure managed domain that is synced from Azure AD to Azure DS

Access on Premise resources using Azure AD Application proxy

we have configured azure active directory pass-through authentication . Need to access on premise resources from the azure deployed application. can we do this by configuring application proxy?. so that on premise application authenticated with azure AD. so the communication between azure application and on premise application be seamless. Is it possible?
I'm not entirely sure if I understand you correctly but what you want is probably possible by using Azure Hybrid Connections: https://learn.microsoft.com/en-us/azure/app-service/app-service-hybrid-connections
You install the Hybrid Connector on-prem, e.g. on a VM, and then for instance an Azure App Service can access certain resources on-prem.
Or for anything more advanced you might want to look at Azure VPN (or ExpressRoute in the long run).

Azure AD connect and Azure ADFS

What is Azure AD connect and Azure ADFS? This is what I have understood: Azure ADFS is exposing on premises AD to Azure cloud and Azure AD connect is means to do that. Am I right?
We need to build an application which needs to authenticate users from different clients' AD. They may or may not have exposed their AD to Azure. Can someone please guide how can this problem be solved?
Azure ADFS is exposing on premises AD to Azure cloud and Azure AD connect is means to do that.
AS of now, the way Azure ADFS works, it essentially provides a way for a company to use AD and ADFS services, without having to deploy themselves. Just like how a Azure has Azure Web App will allow you to have a web server without having your own.
Unfortunately, It does not actually connect or integrate or expose your on premise AD. If you want your clients authenticate against multiple IDs, you do it the old fashioned way, by connecting to the on-premises AD directly. You cannot actually route it through Azure.
One thing which you can do (this will be a huge endeavour) is to move the on premises AD to Azure cloud, which can be done using Azure VMs. Now, that would allow your client to get rid of their on premises AD and use the Azure cloud for everything.

Hosting a web application in Azure that consumes on premise web services and ActiveMQ

I'm looking at ways to host our web site in Azure. The Web application consumes on-premise web services and send/receive messages from ActiveMQ hosted on-premise. Is this possible? Any pointers will be helpful.
Short Answer: Yes, it's possible. Mixing Azure and On-Prem resources is what's called the Hybrid Cloud.
Long Answer:
You can use Azure App Service Environment to setup a Virtual Network with an Azure Web App that will allow for a VPN connection to be setup between your on-premises network and the Azure VNet. If VPN setup isn't an option of you, then you could use the Azure Service Bus Relay service to connect an on-premises WCF Web Service to the Azure Web App. Additionally, a Biztalk Hybrid Connection could be used to tunnel through the firewall between your on-premises resources and the Azure Web App. Hybrid Cloud is fully supported in Microsoft Azure and there are a few options to choose depending on which fits your needs / scenario best.
You can create a VPN on Azure, add the web site to it and then create a site to point VPN connection to add the VM that has the on-premise web service to it.
Another solution, if your web service is developed in WCF, you can use Service Bus Relay with your web service, this will make it accessible from your Azure web site.

Azure AD Domain Services Single-sign-on with Application Proxy using KCD

I have connected an Azure VM with Azure AD Domain Services. I am trying to set up sso for IIS web app which authenticates users using Integrated Windows.
I have followed the guide to setup the Application Proxy and I am stuck at Delegating KCD. https://azure.microsoft.com/en-us/documentation/articles/active-directory-application-proxy-sso-using-kcd/
Has anyone tried to authenticate users with Integrated Windows Authentication via Azure AD SSO?
This is not possible as in Azure AD Domain Services you don't have access to the domain controller so you can't configure KCD for the connector.
Disclaimer - I worked in the App Proxy team :-)
