I have recently configured a Power BI Report Server using Custom authentication and I am able to access the report portal and report server using custom authentication.
But I am facing problem in deploying reports in this Report Server. I am not able to connect using SQL Server Data Tools or Report Builder. Error message: "The permissions granted to user '' are insufficient for performing this operation.".
I tried to deploy the reports by using rs.exe utility but I get an error "Could not connect to server: http://<servername>/ReportServer/ReportService2010.asmx"
I am new to SSRS and PBIRS so please guide me in resolving this issue.
