@Acl 

The @Acl annotation is used to create a new access control list and to protect the controller that is annotation with this ACL accordingly:

// ...
use Oro\Bundle\SecurityBundle\Annotation\Acl;

/**
 * @Acl(
 *     id="user_user_view",
 *     type="entity",
 *     class="OroUserBundle:User",
 *     permission="VIEW"
 * )
 */
public function demoAction()
{
    // ...
}

Options 

class 

type: string

When the type option is set to entity, the fully qualified class name configured with the class option is used to decide whether or not the ACL has to be evaluated when checking if a user has access to a certain class. If the given action is annotated with the ParamConverter parameter, and the class of this parameter is the same as the class parameter from the ACL annotation, the check will be done on the object level (check if the user has access to the given object).

group 

type: string

ACLs can optionally be grouped. A group is identified by its name.

id 

A unique identifier that is used, for example, to reference an access control list with the @AclAncestor annotation.

label 

type: string

A human-readable label that can be presented to the users.

permission 

type: string

When the type is set to entity, access can be granted based on the action that should be performed with a domain object. There are four types of permission which can be granted to a user:

ASSIGN

By default, when a user creates a new entity, they will be the owner of the newly created object. But if they are granted the ASSIGN permission to other users, organizations, or business units, they can transfer ownership to users for which they have this permission.

Note

This permission is not meant to be used in an ACL.

CREATE

The user can create new objects of this entity. Using this permission limit the list of available owners for an entity.

DELETE

The object can be deleted by the user.

EDIT

The user can modify a particular entity.

SHARE

New in version 1.9: Support for the SHARE permission will be introduced in OroPlatform release 1.9.

If a user is granted the SHARE permission on other users, organizations, or business units, they can share an entity with those users which means that those users can then view the entity too.

VIEW

The user is able to see the data of an object.

type 

type: string

The type of resource that should be protected. Possible values are:

action

A certain action in the user interface that is not bound to a particular domain object or a the type (class) of a domain object.

Tip

When using the action type, it is only possible to grant or deny access to a user for a given action. If you want to grant them access for a certain action only for a subset of the data, you can configure ACLs for each object individually by setting the action option to entity and then control the allowed action with the permission option.

entity

When type is set to entity, each domain object can be protected individually which means that access can be granted based on a particular domain object.
