Would it be possible, or maybe it is already possible to see number of users currently logged in to DA?
Also, if user is logged in - to see on what page he/she is on exactly?
The easiest would be to check the /home/tmp/da_sess* files to see who's logged in. If you wrote a plugin, you'd need to set the script to be owned by "diradmin" and "chmod +s" so it can read the files. Make sure it's *very* secure if you do that Add checks to see who's running it and even chmod 770 (+s) with the group set as the admin name who will run it, so you don't get anyone running it who shouldn't be....
That allows
1) admin_name to run it through DA
2) to escalate the script privilges to "diradmin" so that /home/tmp/da_sess* can be read.
I don't think we'll be implementing that anytime soon, so you can really do it however you can figure out Using the API could work too if you grabbed the session ID's from the directory.
