 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 Kerberos5.
 .
 This package contains secure replacements for ftp, telnet, rsh, rlogin,
 and rcp that use Kerberos for authentication.
