The Authentication function allows you to choose between SQL Server Authentication and Windows NT Authentication (recommended by Microsoft). If you already have Windows NT Authentication then you can use this function to Add or Remove the users or groups who can access the HelpSTAR database.
If you are currently using SQL Server Authentication and wish to switch to NT Authentication then you must be a member of the Systems Administrator role on the SQL Server and be logged in exclusively in order to effect this change.
