Came across a strange permission issue today that I thought I’d blog about since it is apparently somewhat common judging by the number of unanswered forum posts about it.

Adding/editing or Testing SSRS Datasources in Report Manager generates a permission error

A developer was trying to add a datasource and use “test connection” in the report manager web interface instead of BIDS which, incidentally worked.  When they tried to save or test the data source, an error occurred “The permissions granted to user “Domain\User” are insufficient for performing this operation. (rsAccessDenied)”  After much websearching and digging through verbose SSRS logs, SQL Traces, Windows Event logs, Process Monitor traces, etc.  I had just about given up hope and turned to twitter to vent about the error.  Luckily, Chris Testa-O’Neill , Doug Lane, and Tamera Clark came to my rescue and headed me down the right path of this being an SSRS catalog permission issue (Thanks again!)

Environment Details

SSRS 2008r2

Folder inheritance is broken and the developer account has Browser permissions on the root folder as well as Browser, Publisher and Report Builder permissions on the sub-folder.  There are no system level permissions for the account.

The Problem

In the SSRS error log I found the following messages which are only slightly more helpful (Highlighted for influence)

System.Web.Services.Protocols.SoapException: System.Web.Services.Protocols.SoapException: The permissions granted to user ‘Domain\User’ are insufficient for performing this operation. —> Microsoft.ReportingServices.Diagnostics.Utilities.AccessDeniedException: The permissions granted to user ‘Domain\User’ are insufficient for performing this operation.
at Microsoft.ReportingServices.WebServer.ReportingService2010Impl.TestConnectForDataSourceDefinition(DataSourceDefinition DataSourceDefinition, String UserName, String Password, String& ConnectError)…

The command is failing on the “TestConnectForDataSourceDefinition” method.  The permissions needed are those required by this method.

The Fix

Near the bottom of the documentation for the TestConnectForDataSourceDefinition the permissions required are listed as “Execute report definition”

Granting this permission is accomplished by connecting to the SSRS server with SSMS and creating a new system role with just this permission

Then grant the new role “Execute Report Definitions” permission

Finally add the user account to the new system role, this is done in report manager under Site Settings ->Security -> New Role Assignment
