| 22 | * Decides whether a proxy list presented via CAS is trusted or not. | |
| 23 | * | |
| 24 | * <P> | |
| 25 | * CAS 1.0 allowed services to receive a service ticket and then validate it. | |
| 26 | * CAS 2.0 allows services to receive a service ticket and then validate it | |
| 27 | * with a proxy callback URL. The callback will enable the CAS server to | |
| 28 | * authenticate the service. In doing so the service will receive a | |
| 29 | * proxy-granting ticket and a proxy-granting ticket IOU. The IOU is just an | |
| 30 | * internal record that a proxy-granting ticket is due to be received via the | |
| 31 | * callback URL. | |
| 32 | * </p> | |
| 33 | * | |
| 34 | * <P> | |
| 35 | * With a proxy-granting ticket, a service can request the CAS server provides | |
| 36 | * it with a proxy ticket. A proxy ticket is just a service ticket, but the | |
| 37 | * CAS server internally tracks the list (chain) of services used to build the | |
| 38 | * proxy ticket. The proxy ticket is then presented to the target service. | |
| 39 | * </p> | |
| 40 | * | |
| 41 | * <P> | |
| 42 | * If this application is a target service of a proxy ticket, the | |
| 43 | * <code>CasProxyDecider</code> resolves whether or not the proxy list is | |
| 44 | * trusted. Applications should only trust services they allow to impersonate | |
| 45 | * an end user. | |
| 46 | * </p> | |
| 47 | * | |
| 48 | * <P> | |
| 49 | * If this application is a service that should never accept proxy-granting | |
| 50 | * tickets, the implementation should reject tickets that present a proxy list | |
| 51 | * with any members. If the list has no members, it indicates the CAS server | |
| 52 | * directly authenticated the user (ie there are no services which proxied the | |
| 53 | * user authentication). | |
| 54 | * </p> | |
