Once an Employee Portal group has been set up, you can add users to the group.
Check that the user has been created in SharePoint.
Open the EP User List window.
In the User ID field enter the ID of the user. Make sure that the ID is identical with the one defined for the user in SharePoint.
In the Language ID field, enter the unique Windows language ID to identify the language of the user.
