Is it possible to view security settings by selected users in Security Auditor?
Yes. To do so, change the view options from the drop-down at the far right in the Users window.
You can view either Users or Classes, and by clicking the Select User / Class button you can select whether to view all of those users or classes or just selected ones.
By selecting specific users or classes, you can wade through the clutter of viewing all of them at once.
Note: Only Users that have access to the selected Company will be shown, regardless of which ones are chosen in the Select Users window. Similarly, only Classes with at least one User that has access to the selected Company will be shown.
