I'm basically wondering if a role inherits all the inheritance that the role it inherits from already inherits (I know, a mouthful).
IE: Do I have to explicitly cite all sub-inheritance:
//Restricted User can do everything a Guest can do:
$acl->addInherit('Restricted User','Guest');
// User can do everything a Restricted User can do:
$acl->addInherit('User','Guest');
$acl->addInherit('User','Restricted User');
// Admin can do everything a User and Restricted User and a Guest can do:
$acl->addInherit('Admin','Guest');
$acl->addInherit('Admin','Restricted User');
$acl->addInherit('Admin','User');
Or does it automatically grab nested permissions, like so:
//Restricted User can do everything a Guest can do:
$acl->addInherit('Restricted User','Guest');
// User can do everything a Restricted User can do
$acl->addInherit('User','Restricted User');
// Admin can do everything a User can do
$acl->addInherit('Admin','User');
