I have a database that has multiple "Files" from what I understand. I come from a relational database background so my terminology may be incorrect. So let's say I have a landing page that links to many different layouts. I've added a user to that via "File -> Manage -> Security...". They can log in but as soon as they try to navigate they receive an error about having insufficient permissions. In the past I've always had to edit existing users, and had to take the time to edit every single file (which takes hours). Do I have to add them to every single on individually? How can I go about adding them to the other layouts/files without knowing their password? There must be a better way of doing this!
