To make the user to have full access to all document in report server.
I retrieve the error message:
"User 'ADVENTUREWORKS\sara' does not have required permissions. Verify that sufficient permissions have been granted and Windows User Account Control (UAC) restrictions have been addressed."
*Inside of my VM player, I have windows server 2012 with SQL server 2012 enterprise
*In order to make sara as a administrator in windows authenication I have created "sara" as a user in AD Administrative Center.
*I have made "sara" as a administrator user as windows authenfication in Windodws 2012 and she is a content manager and system administrator in SSRS at
If the user getting the error when he want to access Report Manager, I guess that may be he have used an incorrect URL. So I suggest that you can try to use this URL:http://localhost/Reports
to check this issue again.
If you have any more questions, please feel free to ask.
