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

149 You need at least <xref linkend="tcl"/>, which is used to drive the
150 testsuite. Furthermore, <xref linkend="dejagnu"/> must be available for
151 some of the tests to run. If you have a former version of MIT Kerberos V5
152 installed, it may happen that the test suite pick up the installed
153 versions of the libraries, rather than the newly built ones. If so, it is
154 better to run the tests after the installation. The t_ccselect test
155 is known to fail.
