      org.globus.security.authorization.providers.FirstApplicableAlg

All Implemented Interfaces:

java.io.Serializable, AuthorizationEngineSpi

public class FirstApplicableAlg
extends AbstractEngine

This combining algorithm returns the first permit or return decision returned by the list of configuired PDPs. Steps: Invoke all configured PIPs in order. Invoke each PDP in order. If a PDP returns a permit or deny, return decision. If no PDPs provide a decision, return indeterminate. Note that entity issuing the decision for each PDP is not considered, that is the resource owner is not matched with PDP decision issuer. Resource owner is used only when an indeterminate decision is returned, with no decision from any PDPs.
