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.
Two factor (SMS) authentication — done right with SMSPassword!
I have always been a fan of two factor authentication, or 2FA in short. Almost all companies and customers I have worked for and with used it in some shape or form. Especially SMS based 2FA — from an administrative perspective it is easy to set up, configure and maintain (if it isn’t you might want to consider switching vendors) and next to that it is also extremely user friendly and secure, when properly implemented that is. And of course, there is no need for any additional (expensive) third party tokens.
