Q:

SQL Server 2012 Reporting Services users get error permissions are insufficient rsAccess

I am running SQL Server 2012 Reporting Services on one server, and accessing data on another SQL Server 2012.  I can publish and run reports myself, both locally on the server and remotely from my desktop.  Other users get access denied, even though they are set up as both system admins for site settings on the report server and as Report Builders, Content Managers, etc for the folder with the reports in it (in other words, I have given them the most permissions I can, and they still cannot access the site). 
I have tried applying these permissions to a group, and when that didn't work, I applied them to single users.  They appear to have the same permissions as I do, but nothing is working for them.   I have read many posts on this error, most of which say to do the things I have already done and re-done.  I am missing something, obviously.  
Report Server Service account is Network Service.  The Report Server database credential is NT Authority\Network Service.  I don't know if that is important or not.  I am a local admin on the server.  Thanks for any help!

finally figured it out.  i had not noticed the "folder settings" on the home page.  i had set permissions on the project folder, but not the home folder.  the documents i read talked about the system admin/user level, and setting permissions for roles on folders, and discussed specifically clicking the drop down arrow next to the folders to set those. 
so the main folder needs its own settings, and it is in a different spot.  thanks!
