Binary package “krb5-user” in ubuntu bionic

basic programs to authenticate using 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 basic programs to authenticate to MIT Kerberos,
 change passwords, and talk to the admin server (to create and delete
 principals, list principals, etc.).
