31 <para>
32 <application>MIT Kerberos V5</application> is a free implementation
33 of Kerberos 5. Kerberos is a network authentication protocol. It
34 centralizes the authentication database and uses kerberized
35 applications to work with servers or services that support Kerberos
36 allowing single logins and encrypted communication over internal
37 networks or the Internet.
