AD FS provides simplified, secured identity federation and Web single sign-on (SSO) capabilities. Federation with Azure AD enables users to authenticate using on-premises credentials and access all resources in cloud. As a result, it becomes important to have a highly available AD FS infrastructure to ensure access to resources both on-premises and in the cloud.

Apr 24, 2020 Citrix Gateway presents all hosted, SaaS, web, enterprise, and mobile applications to users on any device and any browser. It uses nFactor Authentication to authenticate users against on-premises Microsoft AD and leverages Microsoft AD FS for Azure Multi-Factor Authentication (MFA).

Introducing Federation with Azure AD

Federation is a collection of domains that have established trust. The level of trust may vary, but typically includes authentication and almost always includes authorization.
We can federate your on-premises environment with Azure AD and use this federation for authentication and authorization. This sign-in method ensures that all user authentication occurs on-premises. This method allows administrators to implement more rigorous levels of access control.

Architectural Diagram

If we need highly available Federation, then we have to set up “password hash synchronization” option as a backup in case ADFS infrastructure fails.


ADFS configuration prerequisites

  • Windows Remote Management

If the target server is domain joined, then ensure that Windows Remote Managed is enabled
In an elevated PS command window, use command

Enable-PSRemoting –Force

  • SSL Certificate

It’s strongly recommended to use the same SSL certificate across all nodes of your AD FS farm and all Web Application proxy servers. The certificate must be an X509 certificate.
You can use a self-signed certificate on federation servers in a test lab environment. However, for a production environment, I recommend that you obtain the certificate from a public CA

The identity of the certificate must match the federation service name (for example, sts.contoso.com)

  • Name resolution for federation servers

Set up DNS records for the AD FS federation service name (for example sts.contoso.com) for both the intranet (your internal DNS server) and the extranet (public DNS through your domain registrar). For the intranet DNS record, ensure that you use A records and not CNAME records. This is required for windows authentication to work correctly from your domain joined machine.

After configure the prerequisites, next we install Azure AD Connect tool.

Installation of Azure AD Connect

Azure

Download Microsoft Azure Active Directory Connect from here

  • Sign in as a local administrator to the server you wish to install Azure AD Connect on. You should do this on the server you wish to be the sync server.
  • Navigate to and double-click AzureADConnect.msi.
  • On the Welcome screen, select the box agreeing to the licensing terms and click Continue.
  • On the Express settings screen, click Use Customize settings.

Installrequired components

When you install the synchronization services, you can leave the optional configuration section unchecked and Azure AD Connect sets up everything automatically. It sets up a SQL Server 2012 Express LocalDB instance, create the appropriate groups, and assign permissions.

Application

User sign-in

After installing the required components, you are asked to select your user’s single sign-on method. In our case, we’ll select Federation with ADFS.

Connect toAzure AD

On the Connect to Azure AD screen, enter a global admin account and password.

Connect yourdirectories

To connect to your Active Directory Domain Service, Azure AD Connect needs the forest name and credentials of an account with sufficient permissions.

After entering the forest name and clicking Add Directory, a pop-up dialog appears and prompts to create a new account or use existing account required by Azure AD Connect for connecting to the AD forest during directory synchronization.

Azure ADsign-in configuration

This page allows you to review the UPN domains present in on-premises AD DS and which have been verified in Azure AD. This page also allows you to configure the attribute to use for the userPrincipalName.

Domain and OU filtering

By default all domains and OUs are synchronized. If there are some domains or OUs you do not want to synchronize to Azure AD, you can unselect these domains and OUs.

Uniquely identifying your users

The Matching across forests feature allows you to define how users from your AD DS forests are represented in Azure AD. A user might either be represented only once across all forests or have a combination of enabled and disabled accounts. The user might also be represented as a contact in some forests.

Sync filtering based on groups

The filtering on groups feature allows you to sync only a small subset of objects for a pilot. To use this feature, create a group for this purpose in your on-premises Active Directory. Then add users and groups that should be synchronized to Azure AD as direct members. You can later add and remove users to this group to maintain the list of objects that should be present in Azure AD. All objects you want to synchronize must be a direct member of the group. Users, groups, contacts, and computers/devices must all be direct members. Nested group membership is not resolved. When you add a group as a member, only the group itself is added and not its members.

Optional Features

This screen allows you to select the optional features for your specific scenarios.

Create a new ADFS farm or use an existing ADFS farm

You can use an existing AD FS farm or you can choose to create a new AD FS farm. If you choose to create a new one, you are required to provide the SSL certificate. If the SSL certificate is protected by a password, you are prompted for the password.

Specify the ADFS Servers

Enter the servers that you want to install ADFS on.

Specify the service account for the ADFS service

The AD FS service requires a domain service account to authenticate users and lookup user information in Active Directory.

Select the Azure AD domain that you wish to federate

This configuration is used to setup the federation relationship between AD FS and Azure AD. It configures ADFS to issue security tokens to Azure AD and configures Azure AD to trust the tokens from this specific ADFS instance. This page only allows you to configure a single domain in the initial installation. You can configure more domains later by running Azure AD Connect again.

Verify the Azure AD domain selected for federation

When you select the domain to be federated, Azure AD Connect provides you with necessary information to verify an unverified domain. See Add and verify the domain for how to use this information.

Configure and verify pages

Select start the synchronization as soon as possible.

Verify your federation configuration

Gateway

Azure AD Connect verifies the DNS settings for you when you click the Verify button.

In addition, perform the following verification steps:

  • Validate that you can sign in from a browser from a domain joined machine on the intranet: Connect to https://myapps.microsoft.com and verify the sign-in with your logged in account. The built-in ADDS administrator account is not synchronized and cannot be used for verification.
  • Validate that you can sign in from a device from the extranet. On a home machine or a mobile device, connect to https://myapps.microsoft.com and supply your credentials.
  • Validate rich client sign-in. Connect to https://testconnectivity.microsoft.com, choose the Office 365 tab and chose the Office 365 Single Sign-On Test

One of the issues with remote working is the need to run applications that are only available when you are in the office.

In the past this has meant running a Virtual Private Network (VPN) so that the remote device (usually a laptop) appears to be on the local area network (LAN). A very workable solution – but this requires infrastructure and isn’t very flexible. How many companies allow a user to install the corporate VPN software on their home PC?

The Azure AD Application Proxy could be the answer.

The Azure AD Application Proxy explained

The Azure AD Application Proxy is a remote access solution for on-premises resources that is included in all Azure AD Premium subscriptions. It allows you to easily publish your on-premises applications to users outside the corporate network.

Imagine a user, who is at home, who then remembers that they have not entered their expenses into the HR app, but the cut-off is tonight! They don’t have a work laptop, so they would normally have to head into the office. Instead, they switch on their home PC/tablet and navigate to MyApps.microsoft.com.

After they have authenticated using Azure AD, they can select the expenses system from the menu and launch the expenses web application. They get single sign-on (SSO) and are straight into booking their expenses.

Supported application types

The Azure Application Proxy supports a number of application types:

  • Web applications that use Integrated Windows Authentication for authentication.
  • Web applications that use form-based or header-based access.
  • Web APIs that you want to expose to rich applications on different devices.
  • Applications hosted behind a Remote Desktop Gateway.
  • Rich client apps that are integrated with the Active Directory Authentication Library (ADAL).

As long as the application matches one of these then the application proxy is a viable solution. Even when accessing services over a remote desktop environment through a remote desktop gateway.

So, how does it work?

Let’s look at a high-level view of what’s going on:

First, the user accesses their MyApps page, which requires them to authenticate to Azure AD (using all of the conditional access policies that are in place) and then they select the application that they want to access.

This initiates a connection to the app proxy service, which places their request into a queue that is being monitored by the App Proxy Connector (on-premises). The connector then passes the request to the web server and sends the response back to the service which responds to the user.

See Full List On Docs.microsoft.com

As part of the process, the proxy will also try to provide authentication to the application. This takes the user’s authentication details from Azure and then translates them to something that the application may understand.

Create Application Gateway Azure

This can be done with applications that support Kerberos Constrained Delegation (KCD) or SAML. It can also support password vaulting – storing an ID and password for an application securely in Azure.

At the same time, this can increase security for the application by allowing you to leverage Azure AD capabilities such as SSO, conditional access and MFA without making changes to the original application itself.

By adding in conditional access, the user can be validated through multi-factor authentication (MFA), depending on where they are coming from, what the device is, what application they are using and what level of risk the user is showing.
