| The Login Mapping Screen has a special Login user called __default__. This record is used to setup the default login user for any login account that is not specified separately. | |
| If this is a desktop system you might want to specify the user_u or xguest_u user. If this is a terminal server the guest_u user might be a good match. | |
| Then you would need to add the admin users or a Linux group with a different label. Perhaps as unconfined_u or staff_u. | |
| You could use %%wheel to indicate the wheel group. |
