OWA 2010 Form Based SSO

O

As of version 10.69.4.nc NetScaler Gateway and AAA features support OWA 2010 In order to provide SSO when authentication on OWA is form based additional configuration is required. Create a formSSOAction, this provide the NetScaler with the following information: The page in which to complete the Form based SSO...

Windows RT browser based access to Access Gateway Enterprise with WIoNS

W

During a recent project Citrix Receiver for Windows RT version 1.2 was released to the public and by lucky coincidence a majoy stakeholder in the project happened to be the proud owner of a Windows Surface RT which seemed like an ideal opportunity to try out the new Web Interface support for Windows RT. Now being honest I have not got this working when users are logging in via the Metro Citrix...

NetScaler Access Gateway 10: Modify secondary authentication prompt with rewrite action

N

As alot of you will have seen in the article CTX123121 the NetScaler Rewrite feature can be used to modify the look and feel of the Access Gateway logon page, commonly this involves changing the default password prompts created in the login.js file. As the article states these rules may vary from version to version – and they do so I thought I’d add the correct policy for NetScaler...

Updating Provisioning Server target agent in VMWare

U

A quick post – nothing ground breaking really but I encountered a customer at the start of this year who encountered this problem but couldn’t seem to find any information online to help so I thought I’d put some info up here. There are a number of other articles on the net that cover the same subject, I’ve included a few within this post. Provisioning server is a great product for reducing...

Access Gateway Enterprise – Disabling cookies prevents the secondary authentication field displaying

A

As expected this blog has gone a significant amount of time without update. This is mostly because I’ve not had anything particularly interesting to say. So yesterday an Access Gateway Enterprise question was posed to me so I thought I would run through it in case anyone else encounters the same problem. It may not be that interesting Issue A user reported that the secondary authentication...

Powershell – Check ICA response, Check for exiestence of file and uptime of multiple remote servers

P

Following on my previous post I spent some time today refining our ability to check the ICA listener across the farm and created a little powershell script that I thought I’d share. It probably wont be much use to anyone else as it only does a few fairly specific checks but here it is. It’s by no means perfect but does what I need it to Script will: 1. output servers that do not...

The importance of encryption – Web Interface

T

The following is an extract from a document I wrote a while ago which was written to try and highlight the importance of encryption: I’ve played with this type of thing before but it I believe Firesheep, although it may be used with questionable motives, has highlighted to the world quite well the importance of securing your web traffic by creating an exploit packaged so that it can be used...

Issue: XenApp 5 on Windows 2003 – ICA listener ‘down’

I

An issue I encountered when working with one of our customers today. The customer reported that users intermittently received a ‘Protocol Driver Error’ when launching applications from their XenApp 5 (windows 2003) farm. As you know Protocol Driver error is one of those brilliant errors of a million causes but essentially it’s the client telling you “I couldn’t contact the server using the...

Ardbp32.bin Load Balancing – HTTP

A

Thought it was time for an update – This is something I’d previously written when implementing Provisioning Services 5.6 sp1 and XenServer 5.6 FP1 into a a reasonable sized Presentation Server 4.5 farm that wanted to move away from their currrent physical servers to embrace the wonders of virtualization. It’s been said before but load balancing TFTP is difficult, and as...
