title: SSRS site setting permission
body: <p>I'm new to SSRS 2016 and I'm just on the configuration part. I'm facing a problem when trying to add new role or add new user to an existing role, I'm getting a permission error. the user I'm using is a network user and I also define the same user name as local user on the server. both belongs to local administrators group. The Error message I get:"An error has occurred. 
  You do not have permission for this operation. Contact your administrator to obtain the necessary permissions"
  can anyone tell me what permission do I need in order to end this nightmare?
