The Configuration Editor requires a valid Windows or SQL Server login account to connect to the AVEVA Historian. You can specify this account when you register a server. If you did not configure the account upon registration, or if you selected to display a logon prompt, you need to provide a login account as soon as you click the Configuration Editor item in the console tree.
For more information on SQL Server logins, see SQL Server security.
When a connection is established, the Configuration Editor must evaluate the user permissions. If SQL Server authentication is used, the user is a member of the aaAdministrators or aaPowerUsers group, and full permissions are available. In all other cases, read-only permissions are applied.
