 Kerberos is a system for authenticating users and services on a network.
 Kerberos is a trusted third-party service. That means that there is a
 third party (the Kerberos server) that is trusted by all the entities on
 the network (users and services, usually called "principals").
 .
 This is the MIT reference implementation of Kerberos V5.

 This package contains the internal support library for RADIUS functionality.
