Authentication</a></h1>
<p>A careful study of the authentication problem shows that
it should be done during reception of commands and/or jobs
from a remote user and/or spooler. At this time the following
must be done:</p>
<ol type="1">
<li>
<p>The received command must be checked for consistency,
and the remote user and host must be determined.</p>
</li>
<li>
<p>The remote user and host must be authenticated.</p>
</li>
<li>
<p>The command and/or spooling operation must be carried
out.</p>
</li>
<li>
<p>The results must be returned to the remote system.</p>
