<title>Introduction to <application>Heimdal</application></title>

<para>
|
|
<application>Heimdal</application> is a free implementation of Kerberos
|
|
5, that aims to be compatible with <acronym>MIT</acronym> krb5 and
|
|
is backwards compatible with krb4. Kerberos is a network
|
|
authentication protocol. Basically it preserves the integrity of
|
|
passwords in any untrusted network (like the Internet). Kerberized
|
|
applications work hand-in-hand with sites that support Kerberos to
|
|
ensure that passwords cannot be stolen. A Kerberos installation will
|
|
make changes to the authentication mechanisms on your network and will
|
|
overwrite several programs and daemons from the Coreutils, Inetutils,
|
|
Qpopper and Shadow packages.

|

Some sort of time synchronization facility on your system (like <xref

|
linkend="ntp"/>) is required since Kerberos won't authenticate if the
|
|
time differential between a kerberized client and the
|
|
<acronym>KDC</acronym> server is more than 5 minutes.</para></note>
