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.

282 You should consider installing some sort of password checking

284 accept strong passwords. A suitable dictionary to use is shown in
285 the <xref linkend="cracklib"/> instructions. Note that only one
286 file can be used, but you can concatenate many files into one. The
287 configuration file shown below assumes you have installed a
288 dictionary to <filename>/usr/share/dict/words</filename>.

383 This should have created a file in
384 <filename class="directory">/etc</filename> named
385 <filename>krb5.keytab</filename> (Kerberos 5). This file should
386 have 600 (<systemitem class="username">root</systemitem> rw only)
387 permissions. Keeping the keytab files from public access is crucial
388 to the overall security of the Kerberos installation.

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