Connecting to Reporting Server instance from SSMS
I have Power BI Reporting Server Jan 2021 installed. It is configured with Custom Security (as per this: https://github.com/microsoft/Reporting-Services/tree/master/CustomSecuritySample) PBIRS is working abosultely fine. I am able to access the portal and do all the reporting operations. However I am required to update some headers and trying to follow the steps from this link https://docs.microsoft.com/en-us/sql/reporting-services/tools/server-properties-advanced-page-reporting-services?view=sql-server-ver15. I am getting invalid user credentails, no matter what combination I try. Please help!
