</h2>

<div class="mediaobject" align="center"><img src="images/dx-setRootPassword.png" align="middle"></div>
<a class="indexterm" name="BId-drakxid-setRootPassword-it1"></a>
<a class="indexterm" name="BId-drakxid-setRootPassword-it2"></a>
<p><a name="BId-drakxid-setRootPassword-pa1"></a>This is the
most crucial decision point for the security of your <span class="application">GNU/Linux</span>
system: you must enter the <code class="literal">root</code> password.
<code class="literal">Root</code> is the system administrator and is the
only user authorized to make updates, add users, change the
overall system configuration, and so on. In short,
<code class="literal">root</code> can do everything! That's why you must
choose a password which is difficult to guess: <span class="application">DrakX</span> will
tell you if the password you chose is too simple. You're not
forced to enter a password, but we <span class="emphasis"><em>strongly</em></span>
encourage you to do so. <span class="application">GNU/Linux</span> is just as prone to operator
error as any other operating system. Since <code class="literal">root</code>
can overcome all limitations and unintentionally erase all data on
partitions by carelessly accessing the partitions themselves, it
is important that it be difficult to become
<code class="literal">root</code>.
</p>
<p><a name="BId-drakxid-setRootPassword-pa2"></a>The password
should be a mixture of alphanumeric characters and at least 8
characters long. Never write down <code class="literal">root</code>'s
password — it makes it far too easy to compromise your
system.
</p>
<p><a name="BId-drakxid-setRootPassword-pa3"></a>One caveat: don't make
the password too long or too complicated because you must be able to
remember it!
</p>
<p><a name="BId-drakxid-setRootPassword-pa4"></a>The password
won't be displayed on screen as you type it. To reduce the chance of
a blind typing error you will need to enter the password twice. If
you do happen to make the same typing error twice, you will have to
use this <span class="quote">“<span class="quote">incorrect</span>”</span> password when you try to connect
as <code class="literal">root</code>, at least for the first time.
</p>
<p><a name="BId-drakxid-setRootPassword-pa5"></a>You can
change the way users are authenticated on your computer by clicking
on the <span class="guibutton">Authentication method</span> button. The
following authentication methods are available:
</p>
<div class="itemizedlist">
<ul class="itemizedlist" type="disc">
<li class="listitem">
<p><a name="BIdNEW-drakxid-setRootPassword-pa7"></a><span class="guilabel">Local file</span>. Use a local file for all
authentication and user information. This is the default
method.
</p>
</li>
<li class="listitem">
<p><a name="BIdNEW-drakxid-setRootPassword-pa8"></a><a class="indexterm" name="BId-drakxid-setRootPassword-it3"></a><a class="indexterm" name="BId-drakxid-setRootPassword-it4"></a><span class="guilabel">LDAP</span>. Use an
<acronym class="acronym">LDAP</acronym> server for some or all authentication
needs. An <acronym class="acronym">LDAP</acronym> directory consolidates certain
types of information within your organization.
</p>
</li>
<li class="listitem">
<p><a name="BIdNEW-drakxid-setRootPassword-pa9"></a><a class="indexterm" name="BId-drakxid-setRootPassword-it5"></a><a class="indexterm" name="BId-drakxid-setRootPassword-it6"></a><span class="guilabel">NIS</span>. Authenticates users against
a <acronym class="acronym">NIS</acronym> domain. This allows you to run a group
of computers in the same <acronym class="acronym">NIS</acronym> domain using a
common password and group file.
</p>
</li>
<li class="listitem">
<p><a name="BIdNEW-drakxid-setRootPassword-pa10"></a><span class="guilabel">Smart
Card</span>. Uses <span class="application">SmartCard</span>
hardware for providing authentication services.
</p>
</li>
<li class="listitem">
<p><a name="BIdNEW-drakxid-setRootPassword-pa11"></a><a class="indexterm" name="BId-drakxid-setRootPassword-it7"></a><a class="indexterm" name="BIdNEW-drakxid-setRootPassword-it8"></a><span class="guilabel">Windows
Domain</span>. Uses a <span class="application">Windows<sup>®</sup></span> domain controller to
provide authentication services through <span class="application">Active
Directory</span>, <span class="application">Microsoft</span>'s implementation of
<acronym class="acronym">LDAP</acronym>.
</p>
</li>
</ul>
</div>
<p><a name="BId-drakx-pa6"></a>If you select a method other
than <span class="guilabel">Local file</span>, you will be asked to provide
some parameters, which vary from one method to the other. If you
don't know those parameters, you should ask your network
administrator.
