Display system tags in perspective

Hey, I’m trying to display the OSUsername of the user in perspective. I’ve tried binding the label to the system tag and using scripting without success. I found the following topic which says you don’t have access to system tags in perspective:

Here the solution is using the username that is specified in the system props. Unfortunately, that’s not the username I want to display. The tag I want is the OSUsername (System>Client>User>OSUsername), which is not specified in the session props. Is there a way I can have access to this system tag so I can display the username?

No. Web browsers don’t expose this information to end users. The best you could do is require authentication from an active directory user source, at which point you can assume the (Windows) user name.
