 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 a plugin for the OTP preauthentication method
 (RFC 6560), which allows Kerberos tickets to be obtained using
 One-Time Password authentication. This plugin is for use on the KDC; the
 client support is built in to libkrb5.
