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.

141 better to run the tests after the installation. Some tests may fail with

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

319
320 <para>
321 <option>encrypt = true</option> provides encryption of all traffic
322 between kerberized clients and servers. It's not necessary and can
323 be left off. If you leave it off, you can encrypt all traffic from
324 the client to the server using a switch on the client program
325 instead.

368 This should have created a file in

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

377 Exit the <command>kadmin</command> program (use
378 <command>quit</command> or <command>exit</command>) and return
