Applies to: SharePoint Server 2010, SharePoint Foundation 2010
Rule name: The Unattended Service Account Application ID is not specified or has an invalid value
Summary: The Unattended Service Account Application ID setting stores an application identifier (ID) in the registered Secure Store Service. The application ID is used to reference the Unattended Service Account credentials. The Unattended Service Account is a single, low-privileged account that Visio Graphics Service impersonates when it connects to data sources external to Microsoft SharePoint Server 2010, such as Microsoft SQL Server. This account is required to connect to these external data sources. For more information about Visio Graphics Service, see Plan for Visio Services (SharePoint Server 2010) and Plan Visio Services security (SharePoint Server 2010).
