Since the last months Citrix and Novell worked closely together to provide a solution for customers with Novell eDirectory in place. For the Desktop Delivery Controller and the Virtual Desktop Agents Citrix announced an official support statement which could be found here: http://support.citrix.com/article/CTX123281

Costumers with a synched Active Directory / eDirectory only have to be aware of their GINA chaining. http://community.citrix.com/display/ocb/2009/05/07/XenDesktop+and+Novell+eDirectory

For environments where no Active Directory is in place Novell Open Enterprise Server with Domain Service for Windows (DSfW) http://tinyurl.com/yze7y65 have to be installed and configured before XenDesktop.
Due the fact, that DSfW only accepts Kerberos and no NTLM calls the XenDesktop Active Directory Wizard should not be used to prepare the OU.

You'll need to configure the DDC and VDA without using an OU:
http://support.citrix.com/article/CTX118976

I've developed a little cool tool to configure both components using a simple GUI.

On the Desktop Delivery Controller:
1.Set Desktop Delivery Controller without AD OU to enabled
2.Press Set DDC Config Button

On the Virtual Desktop Agents (WinXP,Vista, Win7)
1.Enter the FQDN of the DDC(s)
2.Press SET VDA Config Button

For those of you who would like to set the DDC configuration by using ZENworks or Group Policies I've added an ADM Template (FarmControllers.adm) into the Novell Integration Tool folder.

Download: Novell Integration Tool

Note: This tool is not supported by Citrix Support and if you have any issues try to configure the VDA manually using regedit or leave me a blog comment.

Would you rather watch a short instruction video than reading pages of instructions? Now you can. I've been working with Citrix support team to enhance the existing knowledge base web site with relevant videos.

Here is one example. We recently linked a "CitrixTip" video from our Citrix tip video site with the relevant knowledge base article. You can find the video link in the summary section of the knowledge base article. This video shows how to gather debug trace on Citrix XenApp servers.

Many thanks to the colleagues from our knowledge center team to make this happen.

A lot of partners and customer ask about adding drivers to Dom0
Our Dom0 is using Centos 5 and has all XenServers drivers already built-in.

We only support hardware from our HCL, drivers we deliver with the product and Citrix Ready certified partner solutions.

If you add other drivers to your XenServer host its NOT supported!

The main reason for adding drivers to DOM0 is the request to use cheaper hardware or additional devices like a SCSI Backup drive or a ISDN capi controller.

There is one important thing you should know:

If you get the device up and running in DOM0 doesn't mean that your virtual machine can communicate with the device! 

For example: It's possible to install a Linux driver for a ISDN capi card. So the card is available in DOM0, but there is no Xen driver for the guest to communicate with the card in DOM0. 

Also if it works (maybe for Network or I/O cards) you could run into trouble because our high steep PV drivers are not tested with the driver in DOM0 and that could result in problems or slow performance. 

We think, that the time to get it "up and running" is more expensive than buying supported hardware.

 If you want to compile drivers for xenserver you should follow the official way.

Hello, I'm Mike Stringer and I am responsible for the Support teams in the Americas and India. We are responsible for Supporting all of Citrix's products. I am relatively new to this role but not new to Citrix nor Citrix Support, having run our Escalation teams (which remains one of my responsibilities) for many years. I saw this avenue as a great opportunity to get closer to our Customers and Partners with the goal of gathering valuable feedback on our performance and providing insight into our direction and plans. I have asked my management team to leverage this site to ensure we are heading in the direction that YOU, our Customers and Partners need us to go in.  As the title of this post suggests, I believe Support is one of the key product features that determines Success and Customer Satisfaction with Citrix Solutions. You will be hearing from each of my direct management team members over the next week. Please feel free to start participating and I'll make sure we are very responsive. Thank you -
