SSO to ShareFile with Unified Gateway

Written by Ingmar Verheij on January 8th, 2016. Posted in Netscaler

ShareFileWith the release of NetScaler 11 the Unified Gateway feature became available. Besides that the Unified Gateway enables companies to create a single point of entry for different types of connection (from full blown VPN to ICA proxy and everything in between) it also comes with a landing page where users can access their (SaaS) applications. This is a great addition to the (already long) list of use-cases for a NetScaler in your network.

Now if there’s something users hate than that’s doing things more than once. So when companies make the (ow so logical) transition from “legacy” Windows applications to SaaS applications, so they no longer have to care about how that application works / runs / updates, the end-user is faced with a number of new challenges:

  • Where can I find that new SaaS application?
  • Why do I have to logon again?
  • Why do I have multiple passwords (that change on different moments)?

This is where the Unified Gateway comes into play, it offers a useful landing page where users can find their applications (hey that sounds familiar!). And since the industry made SAML the de-facto standard for authentication to SaaS applications, that might solve the other two challenges!

Long introduction to why I wanted to write this blog, but here’s how you can achieve a Singe Sign-On (SSO) experience from the NetScaler Unified Gateway to ShareFile using SAML.

Citrix NetScaler: Cannot load applet (7u51)

Java Update Available

TIP: NetScaler 10.5 uses HTML5 instead or JRE for most configuration features! Hooraaayyy! – link

On January 14 Oracle released Java Runtime Environment (JRE) 7 update 51. Just like previous updates the raised the security level which could potentially break existing applications. We saw the same when they released 7u45, back then I found a more constructive (but complex) solution to solve a problem where the GUI hanged at “Downloading Applet..

Citrix updated their NetScaler software to meet the requirements of Oracle on December 3rd (download, release notes) – I hope that back then you reverted to a more secure JRE. Unfortunately JRE 7u51 gave me again problems, this time the Java Applet could not be loaded.

Citrix NetScaler: DSR, a poor man’s load balancing solution

Gartner Magic Quadrant for Application Delivery Controllers 2013There are occasions where you need a good load balancer but don’t have the budget. Microsoft offers Network Load Balancing services (NLB) as part of their Windows server operating systems, but although we’re looking for a cheap solution we try to avoid problems. This is where the Citrix NetScaler comes in. Gartner positioned the NetScaler ADC in the leaders quadrant of the Magic Quadrant for Application Desktop Controllers (for the 7th consecutive year in 2013), proving it to be good solution and a reliable partner. Using Direct Server Return (DSR) mode we can offer a “poor man’s solution”.

In this article I’ll explain why you might (not) want to implement Direct Server Return (DSR), how it works and of course how to configure it!

Citrix NetScaler: Cache Microsoft App-V sequences

Citrix NetScaler: Cache Microsoft App-V sequencesRecently I wrote about streaming App-V 5 packages via HTTP. Using caching in IIS performance can be enhanced while resource consumption on the SMB share are minimized. Since we’re using HTTP for streaming it’s not unlikely a load balancer is used to divide the traffic to multiple App-V streaming servers adding another hop.

When a Citrix NetScaler is used to load balancing App-V Streaming Servers you could use Integrated Caching to cache resources. When resources are cached on the load balancer less network traffic is generated. Integrated Caching is part of the Platinum or Enterprise edition with Caching option.

Citrix NetScaler 10.1: Where did the Configuration Wizard go?

Written by Ingmar Verheij on December 23rd, 2013. Posted in Netscaler

Configuration WizardA vanilla Citrix NetScaler shows the configuration wizard right after a users authenticates using the GUI. The configuration wizard enables basic configuration like the NetScaler IP (NSIP), Subnet IP (SNIP), hostname, DNS, Time Zone and Administrator Password.

Sometimes it’s useful to open the configuration wizard after it is closed (for instance if you want to change the host name via the GUI). up to NetScaler 10.0 there was a Setup Wizard button on the System > System Information page.
