An alternate authorization script may be provided to override this script. To do so, make a script that implements the classes declared below. Place the new script inthe <ZENFOLDER>/plugins/alt/ folder. Zenphoto will then will be automatically loaded the alternate script in place of this one.

Replacement libraries must implement two classes: "Authority" class: Provides the methods used for user authorization and management store an instantiation of this class in $_zp_authority.

Administrator: supports the basic Zenphoto needs for object manipulation of administrators. (You can include this script and extend the classes if that suits your needs.)

The global $_zp_current_admin_obj represents the current admin with. The library must instantiate its authority class and store the object in the global $_zp_authority (Note, this library does instantiate the object as described. This is so its classes can be used as parent classes for lib-auth implementations. If auth_zp.php decides to use this library it will instantiate the class and store it into $_zp_authority.

The following elements need to be present in any alternate implementation in the array returned by getAdministrators().

In particular, there should be array elements for: 'id' (unique), 'user' (unique), 'pass', 'name', 'email', 'rights', 'valid', 'group', and 'custom_data'

So long as all these indices are populated it should not matter when and where the data is stored.

Administrator class methods are required for these elements as well.

The getRights() method must define at least the rights defined by the method in this library.

The checkAuthorization() method should promote the "most privileged" Admin to ADMIN_RIGHTS to insure that there is some user capable of adding users or modifying user rights.
