Class AuthorizeManager

java.lang.Object

org.dspace.authorize.AuthorizeManager

public class AuthorizeManager
extends Object

AuthorizeManager handles all authorization checks for DSpace. For better security, DSpace assumes that you do not have the right to do something unless that permission is spelled out somewhere. That "somewhere" is the ResourcePolicy table. The AuthorizeManager is given a user, an object, and an action, and it then does a lookup in the ResourcePolicy table to see if there are any policies giving the user permission to do that action.

ResourcePolicies now apply to single objects (such as submit (ADD) permission to a collection.)

Note: If an eperson is a member of the administrator group (id 1), then they are automatically given permission for all requests another special group is group 0, which is anonymous - all EPeople are members of group 0.
