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.
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.
Since Citrix XenApp and XenDesktop 7.9 the Federated Authentication Service (FAS) is available. Citrix FAS allows a user to login via SAML instead of basic LDAP. This can be any SAML IdP like Google, Okta, Imprivata or Windows Azure Active Directory. In this blogpost i’ll show you how to configure Azure Active Directory for Citrix FAS.Citrix provided a detailed guide for the initial Citrix FAS configuration: also Carl Stalhood wrote a blogpost on how to integratate Citrix FAS with Microsoft AD FS: Configure Azure ADAfter that we have configured Citrix FAS internally we can now configure Azure AD. Sign-in to the Azure portal (i’ll used the classic management page ) Then go to your Active Directory within Azure and open the required Active Directory.Create Azure AD ApplicationNext, go to applications and click Add. Select the option “Add an application from the galary”:Choose Custom Application and give it a name and click next:Now the application has been created and we can configure the details:Configure SSONow we have to configure the defails for this application, so click “Configure single sign-on”.
The first question we will get is how we want to authentication for this application. Select Microsoft Azure AD Single Sign-On and click next.The next page will bring you the important information. Make sure to download the certificate in Base 64 format, you’ll need this certificate later! Also make note of the singe sign-on server url. Select he confirmation checkbox and click next.When the configuration is finished you should get the following confirmation screen (if it fails try to repeat this proces via Google Chrome!)Assign UsersNext we have to assign the users that are allowed to use this Azure AD Application. Choose the Assign Accounts option:Select one ore more accounts that you want to give access to this application and select assign:This completes the Azure AD configuration for Citrix FAS. Now we need to configure NetScaler Gateway to use Azure AD as the IdP for authentication.
Citrix NetScalerNow that we have configured Azure AD we start with configuring NetScaler to use Azure AD as SAML IdP.Add CertificateFirst we need to add the certificate that we’ve downloaded during the Azure AD application creation.
You don't necessarily need a 1:1 mapping of WAP to ADFS server. You need enough to attain your level of required redundancy, which for most would be 2x WAP and 2x ADFS in at least one datacenter, if not duplicated in a 2nd datacenter.
However, if you require additional ADFS servers for performance reasons, you don't need to increase your WAP deployment to match that if they are sized appropriately.Azure Application Gateway is rather new, but it is intended to utilize Azure AD as an SSO source. So, having it proxy and authenticate traffic to another system that is supposed to be for SSO, doesn't seem like a recipie for success.
An increasing number of organisations are turning to Azure MFA to protect public and private cloud resources from intrusion by challenging users with multi-factor authentication. Azure MFA is a powerful, flexible authentication module that is either hosted in Azure Cloud itself or as an on-premises installation.Multi-Factor Authentication in Azure when deployed offers you with the ability to authenticate using:.
Azure Application Gateway Vs Api Management
One-time password. SMS. Phone call. Push notification.The most common method is likely to be push notifications.
Using this method, you simply hit APPROVE on your mobile phone when the prompt appears, and you have completed that authentication factor.In this article, I’ll be showing you how you can authenticate to NetScaler Unified Gateway by using your corporate LDAP credentials, followed by a challenge from Azure MFA. In theory, for a password-less solution, you could go with plain Azure MFA as your primary authentication method.
Authentication is exchanged between Active Directory Federation Services (ADFS) and NetScaler by SAML (Security Assertion Markup Language).I’ve already covered how you can integrate an Azure MFA on-premises installation with NetScaler. Eventually, Microsoft will phase out the on-premises option in favour of Azure cloud MFA.As you are using SAML with ADFS and Azure MFA, you will need to also deploy the Citrix Federated Authentication Service to be able to authenticate with VDAs using a virtual smart card. To keep this article size reduced, you can refer to this link on how to deploy Citrix FAS:AD FS running on Windows Server 2016 has the Azure MFA adapter built-in. This means that we have the option of performing MFA authentication direct from the ADFS login portal. You can also display a custom error message for any user who has not yet registered for Azure MFA.
Note that this only works when initiating sign-on from the Identity Provider. In other words, ADFS can not present a custom error message to any user performing Service Provider initiated logons. Contents:.Configure ADFS – post-deployment:Once you have installed the ADFS role and before configuring it, launch PowerShell and run command Add-KdsRootKey -EffectiveTime ((get-date).addhours(-10)). This command immediately creates a Key Distribution Service Root Key, stored in Active Directory, and allows you to create a group Managed Service Account ( gMSA) as the ADFS service account you create later.
Run this command from a Domain Admin or Enterprise Admin account.Now you can begin your ADFS post-deployment configuration from Server Manager.With Create the first federation server in a federation server farm selected, click Next.Specify a Domain Admin account to perform the ADFS configuration. Click Next.For this step you will need to install a 3rd-party public certificate which matches the FQDN of your ADFS implementation.
In my case, the public ADFS URL will be fs.jgspiers.com. Lastly provide a display name. The Federation Service Display Name will show to all users at log on.
Click Next.Select Create a Group Managed Service Account and enter a unique name for this account. Managed Service Accounts are supported in Windows Server 2012 onwards and come with strict, complex passwords which are changed automatically every 30 days. Click Next.Check Specify the location of a SQL Server database and enter your SQL server details. Click Next.Click Next after reviewing your selections.Click Configure.Create an internal A Record for your ADFS URL. You also need to create an external A Record on your public DNS servers pointing to the ADFS FQDN.Next on your ADFS server, launch PowerShell and run command Set-ADFSProperties -AutoCertificateRollover $false. I am doing this because I do not want to use the ADFS generated Token-decrypting and Token-Signing certificates. Instead we use our own generated through ADCS (Active Directory Certificate Services).
In my case I have two certificates with subjects of:. signing.jgspiers.com. decrypting.jgspiers.comEnrol for the above two certificates, install them on your ADFS server and then launch the ADFS Management console. Browse to AD FS - Service - Certificates - Add Token-Signing Certificate.Select your Token Signing certificate from the list of available certificates to select.
Click OK.Click Add Token-Decrypting Certificate.Select your Token Decrypting certificate from the list of available certificates to select. Click OK.Now highlight your Token Decrypting certificate from the ADFS console and select Set as Primary.Perform the same step for your Token Signing certificate.Select the pre-installed/built-in Token Signing certificate that ADFS provides and click Delete - Yes.Perform the same step for your Token Decrypting certificate.Your Certificates pane will look as below.On your ADFS server, launch an MMC console and add the Computer Certificates Snap-in. Navigate to the P ersonal store, right-click on the Decrypting certificate and click All Tasks - Manage Private Keys.Click Add.Click Object Types and check Service Accounts - OK. Enter the name of the Managed Service Account you used during ADFS configuration.Specify Read permissions for the service account and click OK. Perform the same action on the Decrypting certificate. Afterwards, restart the Active Directory Federation Services service. Configure ADFS with Azure MFA:On each of your ADFS servers launch PowerShell and run command $mfacert = New-AdfsAzureMfaTenantCertificate -TenantId yourtenantidRun command Connect-MsolService to log on to your Azure Active Directory environment.
For more instructions please visit:Run command New-MsolServicePrincipalCredential -AppPrincipalId 981f26a1-7f43-403b-a875-f8b09b8cd720 -Type asymmetric -Usage verify -Value $mfacert. Note: The AppPrincipalId is the Azure MFA client GUID.On your primary AD FS server only, run command Set-AdfsAzureMfaTenant -TenantId yourtenantid -ClientId 981f26a1-7f43-403b-a875-f8b09b8cd720. Note: The ClientId is the Azure MFA client GUID.Restart the AD FS service on each of your servers. You may also need to reboot your WAP servers if they are deployed. Configure ADFS with NetScaler:Navigate back to the ADFS Management Console and browse to AD FS - Relying Party Trusts - Add Relying Party Trust. Using this wizard we create a trust relationship between ADFS and NetScaler.Click Start.Check Enter data about the relying party manually and click Next.Enter a descriptive display name and optional notes. Click Next.Click Next.Check Enable support for the SAML 2.0 WebSSO protocol and enter your NetScaler external URL with /cgi/samlauth appended to the URL.
Click Next.Enter a unique identifier string for the Relying Party Trust. In this example, I’m simply using the NetScaler URL. This same identifier string will later be referenced in the NetScaler SAML policy so take note of it.
Click Nex t.A Relying Party Trust must have an Access Control Policy set against it to govern who can log on. A number of built-in policies come with ADFS.
Alternatively you can create your own. For now I am choosing Permit everyone and require MFA. Click Next.Click Next.Check Configure claims issuance policy for this application. Click Close.Click Add Rule.Using the drop-down select Send LDAP Attributes as Claims. We want to send the users UPN as a claim in the signed token sent to NetScaler from ADFS. Click Next.Enter an appropriate Claim rule name.

Under Attribute store select Active Directory. Under LDAP Attribute select User-Principal-Name. Under Outgoing Claim Type select Name ID. Click Finish.Click OK.Right-click your Relying Party Trust and click Properties.Click on the Endpoints tab. There should be a single entry under SAML Assertion Consumer Endpoints. Click Edit.Double check that the details are as below. Click OK.Click Add SAML.Using the Endpoint type drop-down select SAML Logout. Under Binding select POST.
Under Trusted URL enter adfsurl/adfs/ls/?wa=wsignout1.0. This will act as your logout URL when logging out of NetScaler.
Azure Application Gateway Configuration
Click OK.Click OK.To test ADFS, you can enable the ADFS Initiated Sign-on Page (disabled by default). You will also be using the Identity Provider initiated sign-on anyway, as mentioned previously that is the only way you can have ADFS present a custom error page to unregistered MFA users. To enable the ADFS Initiated Sign-on Page run command Set-AdfsProperties -EnableIdPInitiatedSignonPage $trueNow using your web browser browse to youradfsurl/adfs/ls/idpiniti atedsignon. You should receive an HTML page as below.Next navigate to youradfsurl/adfs/fs/federationserverservice.asmx and confirm you receive an XML response as below. If both tests are successful, you are ready to configure NetScaler with SAML authentication. Configure NetScaler:I’m using NetScaler Unified Gateway, so my SAML policies will be attached to an AAA vServer.First you need to create a SAML Server.
