ACL manager

AclMan is a PHP library designed to manage access control list (ACL).

Requisites

• PHP >= 5.4

• Composer

Features

AclMan has various features:

• Assertions

  It provides an AssertionPluginManager whose goal is to deliver the assertions (i.e., AssertionInterface objects)

• Permissions

  Contains a class, GenericPermission, that is a container of permission options (e.g., a role, a resource, a privilege, an assertion)

• Resources and roles

  It provides a set of traits aimed to check the validity of resources and roles and instantiate their relative classes

• Storages

  AclMan allows you to save the ACL configuration in several layers persistence, via StorageInterface objects and adapters (e.g., ArrayAdapter)

• Services

  A set of classes aimed at the instantiation of ACL objects

Installation

Add ripaclub/aclman to your composer.json.

{
   "require": {
       "ripaclub/aclman": "~0.2.0"
   }
}

Configuration

AclMan library has only two configuration nodes:

1. aclman_storage to configure the persistence layer in which to save your ACL rules

2. aclman_services to configure your services (e.g., a storage and optionally a plugin manager)

Usage (1)

So, here is an example of use. You first need to configure the factories.

Put this PHP array into your configuration file.

'abstract_factories' => [
    'AclMan\Service\ServiceFactory',
    'AclMan\Storage\StorageFactory'
],
'factories' => [
    'AclMan\Assertion\AssertionManager' => 'AclMan\Assertion\AssertionManagerFactory'
]

Then we configure our service.

'aclman_services' => [
    'AclService\Ex1' => [
        'storage' => 'AclStorage\Ex1',
        'plugin_manager' => 'AclMan\Assertion\AssertionManager',
    ],
]
'aclman-assertion-manager' => [
    'invokables' => [
        'assertAlias' => 'assertionClass',
        ...
        ...
    ]
]

Finally, our storage configuration.

'aclman_storage' => [
    'AclStorage\Ex1' => [
        'roles' => [
             // Config specific permission for role Role1 to resources Resource1 and Resource2
            'Role1' => [
                'resources' => [
                    'Resource1' => [
                        [
                            'assert' => null,
                            'allow' => true,
                            'privilege' => 'add'
                        ]
                    ],
                    'Resource2' => [
                        [
                            'assert' => [
                                'assertAlias' => [
                                    'config' => 'test'
                                ],
                            ],
                            'allow' => true,
                            'privilege' => 'view'
                        ]
                    ]
                ],
            ],
            // Config specific permission for all roles to resource Resource1 (e.x public resource)
            StorageInterface::ALL_ROLES => [
                'resources' => [
                    'Resource3' => [
                        [
                            'allow' => true,
                        ]
                    ],
                ]
            ],
            // Config specific permission for Admin to all resource (e.x access to al resource to the admin)
            'Admin' => [
                'resources' => [
                    StorageInterface::ALL_RESOURCES  => [
                        [
                            'allow' => true,
                        ]
                    ],
                ]
            ],
        ],
    ],
]

Our first ACL configuration is now complete. Use it:

$aclService1 = $serviceLocator->get('AclService\Ex1');
$aclService1->isAllowed('Role1', 'Resource1', 'view'); // FALSE
$aclService1->isAllowed('Role1', 'Resource1', 'add'); // TRUE
// ...

Notice the behaviour ...

$aclService1 = $serviceLocator->get('AclService\Ex1');
$aclService1->isAllowed('Role1', 'Resource1', 'add'); // TRUE
$aclService1->isAllowed('Role1', 'Resource2', 'view'); // FALSE
// ...
