the network (users and services, usually called "principals").

This package contains the Kerberos master server (kadmind), which handles
account creations and deletions, password changes, and other
administrative commands via the Kerberos admin protocol. It also
contains the command used by the master KDC to propagate its database to
slave KDCs. This package is generally only used on the master KDC for a
Kerberos realm.
