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.

93 Some sort of time synchronization facility on your system (like

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

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

180 the width of the virtual terminal used for some tests to prevent
181 some spurious text in the output which is taken as a failure. The

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

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

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