Provides a mechanism for creating a KerberosUser from a principal and ticket cache that other components are able to use in order to perform authentication using Kerberos. 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.
