|Message:||The permissions granted to user ‘mydomain\myAccount’ are insufficient for performing this operation. (rsAccessDenied) (ReportingServicesLibrary)|
This error occurs when a user does not have permission to perform an action (for example, they do not have a role assignment that allows them to open a report). If the error occurred while accessing the report server directly through a URL, the exception is mapped to an HTTP 401 error. If the error occurred while using Report Manager or another tool, the error appears in an error page. If the error occurred during a scheduled operation, subscription, or delivery, the error will appear in the report server log file only.
Permission to access report server content and operations are granted through role assignments. On a new installation, only local administrators have access to a report server. To grant access to other users, a local administrator must create a role assignment that specifies a domain user or group account, one or more roles that define the tasks the user can perform, and a scope (usually the Home folder or root node of the report server folder hierarchy). You can use Report Manager or SQL Server Management Studio to create the role assignments.
