About two and a half years ago I published the ultimate Citrix XenDesktop 7.x internals cheat sheet, version 1.0 and it turned out to be a big hit. In the meantime, it has been viewed over 80.000 times already. All the more reason to start working on version 2.0. Since I have been writing about Citrix technologies for the last couple of years I have built up a broad archive, which I can now partly (re) use and re-write to come up with an even more detailed edition, version 2.0 of the Citrix XenDesktop 7.x internals cheat sheet. I would strongly advice you to download a .PDF copy – If you like the blogpost, you’ll love the .PDF, trust me! It includes a full Table of Contents making it easier to navigate.
Inside Citrix: Web Interface & StoreFront — XML-based user authentication
Initially, with the introduction of StoreFront it relied solely on its authentication service for user authentication purposes. This, as you might be aware is different from Web Interface, which will directly contact one of the configured Delivery Controllers where the Broker/XML service will take over. Since Web Interface is still widely deployed and used in (large) production environments (and StoreFront now also supports XML based user authentication) I would like to talk, in a bit more detail about both authentication methods available today.
Demystifying the Citrix XenApp logon, enumeration and launch steps — new details included
This continues to be a topic of interest. Not only is it interesting and fun (right?) to know what is going on underneath the hood once you fill in your user credentials, it can also be very helpful when it comes to troubleshooting certain issues. While I have written about the login, enumeration and launch processes before, again I managed to include a couple of subtle changes/details.
Citrix StoreFront… The tale of two Stores. Hiding, authentication and visuals!
There are a couple of reasons why you might want, or need, to use multiple StoreFront stores. One example would be when dealing with a multi tenant environment and you want to be able to apply different configurations per store. You might have an external and an internal store, hiding certain recourses from your users. And what if you want to apply different authentication mechanisms, or you want to give certain stores and individual look and feel? As we can now easily do with StoreFront 3.0, or easier then before anyway.
The ultimate Citrix XenDesktop 7.x internals cheat sheet!
Ever wondered what happens after a user fills in his or her username and password? What the difference is between internal and external user authentication, resource enumeration and the accompanying launch process? Or what about Web-Interface and StoreFront, do they both have the same authentication mechanism? What are the differences between the server and desktop VDA’s? What about the VDA and XenDesktop internals, what happens inside a VDA when a resource is launched? How does a connection get brokered? Read about this and more during the next 8 (mini) chapters.
