You may get an error in SQL Server Reporting Services when running Change Auditor reports after you publish a report when the coordinator SQL database account is configured with a Group Managed Service Account.
This occurs because an error is encountered when attempting to impersonate the user for the data source.
Change the coordinator SQL database connection account to a Windows authentication user account or an SQL account using the coordinator configuration utility, and then publish a new report or re-publish an existing report.
