You want to provide access to an ibay for guest users with no valid account
create custom template
/etc/e-smith/templates-custom/etc/smb.conf/ibays/50guestok
paste following into template
{
if ( ($ibay->prop('GuestOK') || 'no') eq 'enabled') {
$OUT .= "guest ok = yes\n";
}
}
db accounts setprop IBAYNAME GuestOK enabled
signal-event ibay-modify
NOTE: If the user has a valid account on the server a logon is required. So if you wanted to use this method as a way of providing simple file sharing for all users you need to make sure that the user account on the PC does not match any user accounts on the server
