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

154 better to run the tests after the installation. -->Some tests may fail with
