30 <title>Introduction to MIT Kerberos V5</title>
31
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.

130 To test the build, issue as the <systemitem

132 You need at least <xref linkend="tcl"/>, which is used to drive the
133 testsuite. Furthermore, <xref linkend="dejagnu"/> must be available for
134 some of the tests to run. If you have a former version of MIT Kerberos V5
135 installed, it may happen that the test suite pick up the installed
136 versions of the libraries, rather than the newly built ones. If so, it is
137 better to run the tests after the installation.

268 You should consider installing some sort of password checking
269 dictionary so that you can configure the installation to only
270 accept strong passwords. A suitable dictionary to use is shown in
271 the <xref linkend="cracklib"/> instructions. Note that only one
272 file can be used, but you can concatenate many files into one. The
273 configuration file shown below assumes you have installed a
274 dictionary to <filename>/usr/share/dict/words</filename>.

320
321 <para>
322 <option>encrypt = true</option> provides encryption of all traffic
323 between kerberized clients and servers. It's not necessary and can
324 be left off. If you leave it off, you can encrypt all traffic from
325 the client to the server using a switch on the client program
326 instead.

369 This should have created a file in
370 <filename class="directory">/etc</filename> named
371 <filename>krb5.keytab</filename> (Kerberos 5). This file should
372 have 600 (<systemitem class="username">root</systemitem> rw only)
373 permissions. Keeping the keytab files from public access is crucial
374 to the overall security of the Kerberos installation.

378 Exit the <command>kadmin</command> program (use
