SAML Sign-in to Virtual Smartcard for Virtual Apps & Desktops

The following content is a brief and unofficial prerequisites guide to setup, configure and test accessing virtual apps and desktops authenticated via SAML IdP (Google OAuth) powered by XenApp & XenDesktop 7.14.1+ and NetScaler Unified Gateway 11.1 prior to deploying a PoC, Pilot or Production environment by the author of this entry. The views, opinions and concepts expressed are those by the author of this entry only and do not necessarily conform to industry descriptions or leading best practises.

Why this blog article?
For me as organisations begin shifting to a Cloud native or Cloud First (i prefer hybrid cloud) stratergy they begin too embrace PaaS e.g Citrix Cloud, Office 365 BUT a common major problem is where does the users identity live and do I need replicate it (read-only, passwd hashes e.t.c) and secondly mobilising of data repositories is another major requirement vs. problem. ShareFile can help in solving your data mobilisation problems which I will follow up in a separate blog article in the future to expand upon this, but for now back to SAML and Identity.

Utilising the Federation Authentication Service or FAS for short which is part of XenApp and XenDesktop (see feature matrix – https://www.citrix.co.uk/products/xenapp-xendesktop/feature-matrix.html) in-line with NetScaler UG enables organisations to solve numerous problems about identity (where is lives vs. its synced to data centres A through C e.t.c) enabling access to any type of app fronted by NetScaler Unified Gateway working inline with FAS.

NetScaler for me is your organisations front door (knock knock) e.g https://go.axendec.com or if you know me #10 Downing Street from on any device and it controls how the users authenticates requirements e.g AD, AAD, SAML vs. OAuth 2.0, Biometrics (e.g VeridiumID watch – https://www.veridiumid.com/video-citrix-ready-partnerspeak-veridium/ which is Citrix Ready and be sure to check out https://www.veridiumid.com/biometric-authentication-technology/biometric-connectors/), however in this scenario i’ll focus on access from devices that support a modern web browser (HTML5) to keep it simple. The below table depicts a user that has successfully loaded onto NUG with SMAL vs. OAuth 2.0 credentials and they can go left towards SaaS web apps or right towards virtual apps & desktops where FAS + StoreFront + Int Windows CA will generate a virtual smart card from the SAML token passed from NetScaler to SSO onto the required resource e.g Windows Server 2016 virtual desktop.

PoC SuGgEsTeD Architecture Diagram – BASIC
I have gone for a very simple diagram approach here to help those will little to no knowledge on SAML, OAuth 2.0, AD Shadow accts, virtual smart cards get up to speed.

User Login Flow (Not Step by Step its High Level)
1. The user navigates to the SAML IdP logon webpage setup, configured and hosted by NetScaler UG.
2. The user is automatically redirect to the Google auth login web page to authenticate.
3. Once the user is successfully authenticated at Google they are re-directed back to the NetScaler UG and auto signed in and auto redirected (Responder Policy) to the configured Unified Gateway (my use case here) or ICA Proxy vServer.
4. The user can then select from a choice of Full vs. Clientless VPN or Virtual Apps & Desktops (Selected). Note that in the username will be user@domain while still on the NetScaler UG.
5. The user is SSO onto ReceiverforWeb hosted + powered by StoreFront and the user selects to launch an there choosen HDX virtual app and or desktop(s), you’ll now notice that the username is now first, last name.
6. StoreFront initiates and generates a ICA/HDX file for the user while communicating with FAS + internal Windows CA to generate a virtual smart card for the user that will be used to SSO the user onto there requested resource(s) e.g a Virtual Desktop.
7. The user receives the ICA/HDX file and Receiver automatically launches his/her virtual app and or desktop.

The Actual Login Flow
Coming…*

Pre-requistes & System Requirements – Google OAuth 2.0
1. Navigate to https://console.developers.google.com/projectselector/apis/credentials and sign-in with your Google credentials.
2. Select “Credentials” under API Manager then select to “Create” a Project
3. Enter in a new “Project Name” and read and review Googles EULA and notification service about updates etc.
4. Google will create your Project
5. Select “Create credentials” and from the drop down select “OAuth client ID”
6. Configure “OAuth consent screen” the bare minimum is to select “Product name shown to users” e.g MYProJectName and then select “Save” you can return later and complete …
7. Now you need to create a client ID select the application type to be “Web Application”
Enter in a friendly name:
– For “Authorized JavaScript origins” enter in “:4443”
– https://YOUR-FQDN:4443
– For “Authorized redirect URIs” enter in “:4443”
– https://YOUR-FQDN:4443/oauth/login
– Select “Create” twice
Google will now create your OAuth credentials and a popup screen will appear with your “Client ID” e.g xnxnxnxnxnxnxnxnxnxnx.apps.googleusercontent.com and “Client Secret” e.g 123456789xnxnxn
8. Now store of copy of these for later in a safe please as you’ll need it for the NetScaler configuration later.

Pre-requistes & System Requirements – Citrix
NetScaler
1. Review the deploying NetScaler guide for your chosen resource location at – http://docs.citrix.com/en-us/netscaler/12/deploying-vpx.html. If your wondering what a Resource Location click this link – http://docs.citrix.com/en-us/citrix-cloud/overview/about/what-are-resource-locations.html.
2. Download vs. deploy your NetScaler virtual appliance on your own terms e.g upload and boot on a hypervisor vs. deployed via a IaaS market place.

– Traditional hypervisors configurations for PoC vs. Home purposes only 2vCPU 2-4GB of RAM
– Cloud hypervisors e.g Azure, AWS for PoC vs. Home purposes only 2vCPU 3.5GB or RAM

3. Licensing Your NetScaler
3.1 You’ll need to license the appliance so obtain trial of e.g VPX 1000 and or 3000 from http://store.citrix.com/store/citrix/en_US/pd/productID.278306700/ThemeID.33753000 or search for Citrix Eval Store at Google.com.
3.2 The above link should redirect your to the NetScaler ADC part of the Eval Store
3.4 Select model type of “VPX” then select variation e.g “1000 vs. 3000 Platinum” and for duration select “30, 60 or 90 Days“.
3.5 Complete the onscreen steps and please note that you will require a valid Citrix.com account or you need to create an account in order to complete the trial request to obtain the eval license.
3.6 Once you’ve received your eval license via email navigate to at https://www.citrix.com/account/toolbox/manage-licenses/allocate.html and select find and allocate your licenses or look for the licensing button (link) and select it.
3.7 If your eval license it not visible e.g created by a Citrix rep or one of our partners –https://www.citrix.com/buy/partnerlocator/ select “Don’t see your product?” top right-hand side (small text!). A pop-up appears now enter in the eval lic provided in the format of “NNNN-XXXXX-XXXXX-XXXXX-XXXXX” and select to continue.
3.8 You will need to enter in the Host Id of your NetScaler it can be found once logged in using the NS Admin Web UI “NetScaler -> System -> System Information” then look under the heading “Hardware Information” and you find “Host Id” copy and paste it into the required field and then download the license file.
3.9 In the NS Admin Web UI click the cog icon top right then select licensing and upload the license and select to reboot the NS to apply the license.
3.10 Your NetScaler is now licensed now simple enable the required features that you need vs. require by right clicking a feature e.g NetScaler Gateway select “enable” e.t.c

4. If your in a Public Cloud setup your (Network) Security Groups to allow you external traffic to your NetScaler and i’d suggest that your disable SSH on port 22 from the world and only enable https 443 and use a Windows server + PuTTY within your Azure RG vs. EC2 VPC to interact with your NetScaler. Note: I am keeping it simple here re DMZ/Edge vs. TRU vs. Mgmt networks. Traditional rules apply for Private Cloud setups or WWW vs. DMZ vs. TRU vs. Mgmt networks.

Federated Authentication Service (FAS)
1. Download FAS Software is part of the XAD 7.9+ ISO – https://www.citrix.co.uk/downloads/xenapp-and-xendesktop/ and select 7.15 LTSR
2.
System Requirements – http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-13/secure/federated-authentication-service.html
3. Deploy GPO Policies – http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-13/secure/federated-authentication-service.html#par_anchortitle_6ba9/

Suggested Top 10 for 2016
This is numbered 1 through 10 but in reality is in no particular order!

1. E-mail discovery for Citrix Receiver using DNS SRV records – http://docs.citrix.com/en-us/receiver/windows/4-3/receiver-windows-install-wrapper/receiver-windows-cfg-command-line-42.html internally and externally on the Gateway – http://docs.citrix.com/en-us/netscaler-gateway/10-1/ng-xa-xd-integration-edocs-landing/ng-clg-integration-wrapper-con/ng-clg-session-policies-overview-con/ng-clg-storefront-policies-con/ng-clg-storefront-email-discovery-tsk.html.
2. Implement SplitDNS or more technically correct “split-horizon DNS” – https://en.m.wikipedia.org/wiki/Split-horizon_DNS my favourite personally over email based discovery :-)!
3. Brand your NetScalers (Unified) Gateway – http://docs.citrix.com/en-us/netscaler-gateway/11-1/vpn-user-config/custom-portal.html and App Store (StoreFront) – http://docs.citrix.com/en-us/storefront/3-7/manage-citrix-receiver-for-web-site/unified-receiver-experience.html to match and keep it clear, clean and simple!

4. Implement HDX Adaptive Display v2 available in 7.11+ – http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-11/policies/reference/ica-policy-settings/graphics-policy-settings.html as your default Graphics Mode and if you can’t then Thinwire Compatible Mode – http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-11/hdx/thinwire.html.

5. If using Skype for Business 2015 or 2016 implement the HDX RealTime Optimisation Pack 2.x.n http://docs.citrix.com/en-us/hdx-optimization/2-1/hdx-realtime-optimization-pack-overview.html to offload the video/audio to the local end-points (Windows, Mac and Linux) saving on backend compute and density loss for XenApp.*

6. Implement domain pass-through for internal users – http://docs.citrix.com/en-us/storefront/3-7/plan/user-authentication.html.
7. Deploy the (latest) HTML5 Receiver for remote access – http://docs.citrix.com/en-us/receiver/html5/2-2/user-experience.html.

8. When using Citrix Receiver for Windows (with HDX engine 14.4), the GPU can be used for H.264 decoding wherever it is available at the client – http://docs.citrix.com/en-us/receiver/windows/4-5/improve.html.
9. Deploy Self-Service Password Reset (SSPR) – http://docs.citrix.com/en-us/self-service-password-reset/1-0.html.

10. The most difficult to justify probably re the cost(s) but assigning a low end vGPU GRID profile or utilising the Intel Iris Pro Graphics with XenServer 7 to provide enough/suitable GPU capacity to all virtual apps & desktops (oldISH and modern) provides a much better experience so setup a PoC to see and try if for yourself and finally NVidia now supports H.264 offloading onto there GRID Cards in 7.11 🙂 – http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-11/whats-new.html#par_anchortitle_59c9.

Introduction
The following capability is also referred to as Selective use of H.264, Selective H.264, HDX Adaptive Display v2 and Hybrid mode – https://www.citrix.com/blogs/2016/09/28/hdx-graphics-gone-hybrid/ but in this blog post it’s referred to as “HDX Adaptive Display v2” but its technical accurate name from eDoc’s is “Selective use of a video codec (H.264) to compress graphics” as reffered to here – http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-11/whats-new.html#par_anchortitle_59c9.

Overview
In the release of XAD 7.11 (Seven11) a new Thinwire HDX policy was released which is part of the following policy Use video codec for compression” with the following option selected “For actively changing regions” which enables HDX Adaptive Display v2 – http://docs.citrix.com/en-us/xenapp-and-xendesktop/7-11/whats-kmnew.html#par_anchortitle_59c9 which blends the following Citrix HDX Graphics modes H.264 & Thinwire Compatible Mode together to offer the best UX but also to provide a balanced apporach by implementing the most right vs. relevant HDX graphics mode to offer the best rich & HD experience or near to local-like experience while balancing all compute, network resources between the server and or desktop VDA over the organisational network, internet to the users end-point.

The following CTX blog article – https://www.citrix.com/blogs/2016/09/28/lossless-compression-lowering-the-cost-of-pixel-perfection/ most accurately describes the what, the how and the why? So be sure read it and watch the following YouTube video demonstration entitled “Citrix Desktop Master Class – Adaptive Display v2 Demo by Lee Bushen“.

Understanding Actively Changing Regions
If you take a look at the below example of a YouTube web page (rendered in HTML in Oct 2016) e.g delivered as a virtual app published internet browser or a virtual desktop and you access the above YouTube web page HDX Adaptive Display v2 will selectively utilise H.264, Thinwire and overlay lossless text.

To further understand this in greater details please refer to this Citrix blog article first and foremost https://www.citrix.com/blogs/2016/09/28/lossless-compression-lowering-the-cost-of-pixel-perfection/ and then watch
Citrix Desktop Master Class – What’s New in XenApp/XenDesktop 7.11 – Sept 2016available at – https://www.youtube.com/watch?v=rGHdTX202_U but scrub to 1:12:00 if you just want to understand HDX Adaptive Display v2 in greater detail.

The CLEAN installation that I performed did not have any issues or errors however the when creating the machine catalog for Windows Server 2016 TP5 even installing the Server DVA 7.11 it will revert to recommended VDA release of 7.8 only so you have been warned!

Once Microsoft releases Windows Server 2016 officially I will follow-up with an overview of setting up and configuring XAD 7.11 on Windows Server 2016 hosted on Microsoft Azure.
