krb5_newrealm — Create a new Kerberos Realm
This script attempts to create a Kerberos realm. It assumes that none
of the realm components exists, except for the /etc/krb5.conf file.
(Normally this file is automatically generated at package installation,
but if you skipped the configuration step, you will need to manually
generate this file before running krb5_newrealm.) It creates the
database, initializes the stash file in /etc/krb5kdc/stash containing
the master key for the database, starts the KDC and Kerberos admin
server, and creates a stub /etc/krb5kdc/kadm5.acl file.
