By encapsulating this information into a Controller Service and allowing other components to make use of it an administrator is able to choose which users are allowed to use which ticket caches and principals. This provides a more robust security model for multi-tenant use cases.</p><h3>Tags: </h3><p>Kerberos, Ticket, Cache, Principal, Credentials, Authentication, Security</p><h3>Properties: </h3><p>In the list below, the names of required properties appear in <strong>bold</strong>.
