documentation for MIT Kerberos

 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 installation, administrator, and user reference
 manuals for MIT Kerberos and the man pages for the MIT Kerberos
 configuration files.
