I'm trying to create a ReportServer database on a different server (Server_AT) other that my Reporting Service server (Server_RT). ON Server_AT, I created the RSExecRole as per the script here. Then created a login 'Reporter' with user 'Reporter' and assigned the RSExecRole. Now when I use the configuration wizard -> create a new ReportServer database-> enter the SQL Server credential for Reporter as prompted-> and finish.
Now the process fails - constantly with on error after another that one of permissions in the RSExecRole cannot be found. The ReportServer database does gets created on Server_AT but the user is dbo- but I am not able to connect to this database either (when I try next time).
What am I missing here?
