I have a userID/userName, and I want to know if that user is currently loggedon to the SharePoint site.
The SPUser object does not seem to have any of these properties. I looked at Membership.GetUser("username").IsOnline, but that threw an "Access Denied" error.
Is there any way to achieve this?
UPDATE: I even tried to run with ElevatedPrivelges. The error is that current user does not has access to /APP_DATA folder.
