Autenticação de usuários com tabela diferente ( Ex: tabela funcionarios ) desculpem a simplicidade mas o importante é que deu certo :)

auth.php

<?php

//app/config/auth.php

return array(

	'driver' => 'eloquent',
	'model' => 'User',
	'table' => 'funcionarios', //specification table to be used
	'reminder' => array(
		'email' => 'emails.auth.reminder',
		'table' => 'password_reminders',
		'expire' => 60,
	),

);

route.php

<?php

/*
| Metodos da Classe UserController
*/
Route::any('/login',[
		"as"   => "login",
		"uses" => "UserController@login"
]);

Route::any('/logando',[
	"as"   => "logon",
	"uses" => "UserController@logon"
]);


Route::get('/logout', 'UserController@logout');
