AD security group issues in SharePoint 2013 Integrated Mode

Question

Hello,
Sorry if this is the wrong forum, I'm not sure if this is a SharePoint issue or a Reporting Services configuration issue (or if it should be in a SharePoint forum regardless).
I have SSRS2012 on SharePoint 2013 in integrated mode. We are doing item level permissions, which means we have an AD security group Reports-All with
Read to the Reports document library, then each actual report has unique permissions. We have a report with the ProjectManagers AD
security group on it with Read (plus some other stuff to let them manage subscriptions), and another AD security group ProjectUsers with
just Read access so they can open the reports. The data source used by this report has the AD security group I mentioned before, Reports-All,
with Read.
At a SharePoint level, things appear to work. When a user in ProjectManagers or ProjectUsers browses
to the library, they see only the 3 reports that those two security groups have permission to see (out of a lot more in the library). That means SharePoint is reading those security group memberships correctly as far as I can tell.
The issue is when a user in ProjectManagers or ProjectUsers clicks
on a report, they get a reporting server based error message, and the ULS logs have an error specific to the user trying to run the report.
Microsoft.ReportingServices.Diagnostics.Utilities.AccessDeniedException: The permissions granted to user 'MyDomain\MyUser' are insufficient for performing this operation. (Fault Detail is equal to Microsoft.ReportingServices.ServiceContract.RsExceptionInfo)
If I add that specific user with Read permissions to the report and the data source, they are then able to run the report without errors. It seems like some Report Server component is not liking the fact that I'm using security groups. 
Has anyone seen this behavior with AD security groups? Any ideas on why my environment does not want to work properly with those even though AD security groups are working fine for other non-Reporting Services files?
Thanks,
Aaron

Hi aaronzott,
According to your description, you configured SSRS 2012 of SharePoint integrated mode. You added read permission to reports and data source to AD security group Reports-All, then added just read permission to ProjectManagers and ProjectUsers groups. When
users in ProjectManagers or ProjectUsers groups click report, the error message occurred. After you added Read permissions to the report and the data source to the groups, they can preview the report without errors.
Report definition permissions are defined through List permissions on the library that contains the report, but we can set permissions on individual reports if we want to restrict access. Set properties on a report including data source connection information,
processing options, and parameter properties. Edit Items on the library that contains the report or on the individual report. We also need to have view permissions on a shared data source (.rsds) to select it for use with the report.
