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

134 <para>
135 To test the build, issue as the <systemitem

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

178 <application>Python</application> detection. The second one increases
179 the width of the virtual terminal used for some tests to prevent
180 some spurious text in the output which is taken as a failure. The

183
184 <para>
185 <option>--localstatedir=/var/lib</option>: This option is

203 <para>

205 the package: it does not recognize its own verto library installed
206 previously. This is not a problem, if reinstalling the same version,
207 but if you are updating, the old library is used as system's one,
208 instead of installing the new version.

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

375 This should have created a file in

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