Wow! What a mouthful of a post title !
So, the purpose of this is to walk you through the process of adding a connection to your Azure Resource Manager Datacenter from Citrix Studio manually.
Following my previous posts about ADFS and MFA I have a on-premises ADFS instance linked to Microsoft Azure Multi Factor Authentication. I want to use this method to authenticate to an Azure AD hosted in the cloud and add a hosting connection to Citrix Studio. Essentially I want the microsoft login to hand off authentication back to my ADFS instance to authenticate the user and deal with MFA.
For context my internal domain name is bretty.local – my external owned domain is bretty.me.uk – my ADFS URL is sts.bretty.me.uk both internally and externally.
So, lets get started.
Active Directory Domain Suffix
The first thing I need to do is add bretty.me.uk as an additional UPN suffix for my domain. This is so that I can authenticate externally and internally using my bretty.me.uk owned domain.
Open up Active Director Domains and Trusts, right click the top level and click properties
Add your external domain as an available domain suffix
Azure Active Directory
Next we need to set up an Azure Active Directory and link it to our on-premises domain. There are a number of options and ways that you can configure this however in this post I am going to use directory sync to sync my AD to Azure and link back to my ADFS service for user authentication.
Open up the OLD Azure Admin Console by going here:
Navigate to Active Directory
Select Directory at the top
Click Add to create a new directory
Fill out the details for your new Active Directory, give it a .onmicrosoft.com domain name and select the location
Click ok to create the new directory
Next you will need to add and verify the external domain name that you own (in my case bretty.me.uk)
Click to add a domain. Add your external Domain name and DONT put a tick in the “I plan to configure this domain for SSO”
Click Add then next
This screen will ask you to verify that you own the domain. You will need to add a TXT DNS record to your domain as specified by the screen and verify the domain. This may take some time to achieve because of DNS replication but make sure you verify your domain before you try to install Directory Sync.
Next you need to set-up Azure AD Connect on one of your domain controllers. Head over to the following site:
download and install the AD Connect Software.
I am not going to run you through the options around AD Connect as there are many different ways in which you can deploy this. In this instance I opted to use ADFS and pointed the Azure AD Connect to my existing ADFS service I have built in previous posts. The wizard to set this up is very straight forward – you will just need service accounts and details of you on premises ADFS Service.
Once installed open up Azure AD Connect
click on current settings and you will see your current AD Connect Settings
What’s being synchronised
Finally your ADFS Sync details
Switch back to your Azure Portal and you will see the integration with Active Directory is all up and running
If you switch to your users tab you will see the Admin user you originally set up
as well as your synchronized local Active Directory user accounts
Whilst in the Azure portal you will need to add your local admin account to the Azure Subscription as an co-admin
Head over to settings
Click on Users/Access and add your local domain account to the subscription as an administrator
Test Azure AD and Local ADFS Setup
Next you will need to enable ADFS to use forms authentication locally on the intranet to allow Citrix Studio to add the hosting location
Open up the ADFS Management Console
If you check under Relying Parties you will see that the AD Connec t Wizard has added a relying party for Microsoft Online
Lets test logging into Office 365 as a local domain user. Open up the Office 365 Login page and log in as a local domain user (email@example.com in my case)
Note that I have been redirected to my local ADFS Service for authentication
Once Logged in Azure MFA is prompting for credentials as I am logging in from an external machine
All done – authentication is working as expected
Back in the ADFS Management Console – open up authentication methods and enable Forms Authentication for the Intranet Location
That’s it for ADFS – you now need to set up the Azure Service Principal ready to connect to from Citrix Studio.
Microsoft Azure Service Principal
NOTE: All commands will be listed in this format
Open up a powershell command as an administrator from a machine on your local network
To install the Azure RM powershell commands
Log into your Azure Account
When prompted log in with your Subscription Admin details
All logged in!
List all your available subscriptions in Azure
Select your subscription you want to connect to from Citrix Studio
select-azurermsubscription -subscriptionid YOURSUBIDGUID
Set up your 4 variables you will need for the Service Principal
$SubscriptionId = "YOUR-SUB-ID" $AADUser = "YOUR CO-ADMIN USER ACCOUNT ADDED EARLIER" $ApplicationName = "XenDesktopConnect<--CAN BE ANY NAME WITHOUT SPACES" $ApplicationPassword = "MAKE-UP-A-SECURE-PASSWORD"
Create your Azure AD Application
$AzureADApplication = New-AzureRmADApplication -DisplayName $ApplicationName -HomePage "https://localhost/$ApplicationName" -IdentifierUris "https://$ApplicationName" -Password $ApplicationPassword
Create your Service Principal
New-AzureRmADServicePrincipal -ApplicationId $AzureADApplication.ApplicationId
Assign the role to the SP
New-AzureRmRoleAssignment -RoleDefinitionName Contributor -ServicePrincipalName $AzureADApplication.ApplicationId –scope /subscriptions/$SubscriptionId
So, lets jump over to Citrix Studio and seer what’s required to add a new hosting connection to Azure RM
Type to list your subscriptions – make a note of the subscription ID
Type the following to get your application ID
Switch back to your domain controller and open up Azure AD Connect
Click on View Current Configuration
You will see your Azure Directory ID listed there
Add Connection in Citrix Studio
So, its finally time to add the hosting connection in Citrix Studio and start to create some resources
Open up Citrix Studio and select hosting – click to create a new hosting connection.
Put in your subscription ID you got earlier and give your subscription a description then click on use existing
Your Subscription ID will be filled out automatically
Enter all the other details your got in the prior steps
Select the region you want the machines to be hosted (you will have to have set up networking and storage in this region
Select the network you want the provisioned machines to use
Build a Machine Catalog
To build a machine catalog you will need a VM build in Azure with teh VDA installed and it has to be powered off
Select to create a new machine catalog and select the Server or Desktop OS as appropriate. When prompted select your new hosting connection
Browse to the resource group, storage location, vhd and select the image you created to use as a tempplate
Finish the wizard and let Azure Create the catalog for you
You can see in the details at the bottom that it is an Azure hosted MCS Catalog
That’s it, all you need to know to set up and configure an Azure RM hosting Connection in Studio manually,
