Forms Authentication Error: User '' does not have required permissions. Verify that sufficient permissions have been granted and Windows User Account Control (UAC) restrictions have been addressed

Question

I created a custom security extension following the steps listed in the Readme_Security Extension Sample. It works fine if I login as the user that is specified AdminConfiguration section of the rsreportserver.config file but if I
log in as another user, I get this error: User '' does not have required permissions. Verify that sufficient permissions have been granted and Windows User Account Control (UAC) restrictions have been addressed.  I've added the user to both System Administrator
and System User roles to try to get it to work but still no luck.
Does anyone know how to fix this?
Thanks.

Hi MetronM,
The issue is due to that user have no permission to access the report server. In report manager, Reporting Services includes predefined roles that we can assign to users and groups to provide immediate access to a report server. Each role defines a collection
of related tasks.
You can refer to the following steps to assign corresponding role to the user.
Open report manager.
Click “Folder Setting” button. 
Click “New Role Assignment” icon.
Type the user name and select the corresponding role.
There is an article about Granting Permissions on a Native Mode Report Server, you can refer to it.
