This java.security.Permission class governs the delegation of Kerberos tickets from a Kerberos principal to a Kerberos service for use on behalf of the original principal. The target name of a DelegationPermission consists of the principal names of two Kerberos services. The first specifies the service that is being delegated to, and the second specifies the service that is to be used by the first on behalf of the original Kerberos principal.
