<span class="emphasis"><em>Linux-PAM</em></span> has the potential
to seriously change the security of your system. You can
choose to have no security or absolute security (no access
permitted). In general, <span class="emphasis"><em>Linux-PAM</em></span>
errs towards the latter. Any number of configuration errors
can disable access to your system partially, or completely.
</p><p>
The most dramatic problem that is likely to be encountered when
configuring <span class="emphasis"><em>Linux-PAM</em></span> is that of
<span class="emphasis"><em>deleting</em></span> the configuration file(s):
<code class="filename">/etc/pam.d/*</code> and/or
<code class="filename">/etc/pam.conf</code>. This will lock you out of
your own system!
</p><p>
To recover, your best bet is to restore the system from a
backup or boot the system into a rescue system and correct
things from there.
