<p>This module provides access to the Unix shadow password database. It is

available on various Unix versions.</p>

<p>You must have enough privileges to access the shadow password database (this
100
usually means you have to be root).</p>
101
<p>Shadow password database entries are reported as a tuple-like object, whose
102
attributes correspond to the members of the <code class="docutils literal"><span class="pre">spwd</span></code> structure (Attribute field

below, see <code class="docutils literal"><span class="pre"><shadow.h></span></code>):</p>
