When it comes to deploying a highly available CAS server, one of the chief concerns is to choose a technology that is capable of sharing CAS-generated tickets across multiple server nodes. The task of managing and administering CAS tickets is handled today by a Ticket Registry component that is backed by a variety of technologies able to ... Read More
