I am having a lot of trouble getting a user (other than my own user account) set up to use the web portal on SSRS 2016. With my user account I can view and manage all the reports, data sources, and other objects but now that I am trying to grant access to another user, it is not working.
First I added an active directory domain group she is part of to the System role then, when that didn't work, I added her group to the System Administrators role. She was still getting the same error about insufficient privileges so I added her user account explicitly to the System Administrators role but the problem is not resolved.
In the error log at "C:\Program Files\Microsoft SQL Server\MSRS13.MSSQLSERVER\Reporting Services\LogFiles\Microsoft.ReportingServices.Portal.WebHost_10_04_2016_11_50_41.log" I see log entries like this: "Microsoft.ReportingServices.Portal.WebHost!library!8!10/04/2016-12:56:15:: e ERROR: Throwing Microsoft.ReportingServices.Diagnostics.Utilities.AccessDeniedException: , Microsoft.ReportingServices.Diagnostics.Utilities.AccessDeniedException: The permissions granted to user 'MYDOMAIN\ThisUser' are insufficient for performing this operation.;"
I guess that means the authentication is working just fine, it is the authorization that is failing.
I am probably doing something silly here since I am not a veteran SSRS administrator. Any help would be much appreciated.
