<code class="function">auth_enumerate</code> enumerates all of the available accounts.
<code class="function">auth_enumerate</code> repeatedly calls
<code class="function">callback_func</code>, once for each account.
<code class="function">callback_func</code> receives the following arguments:</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p>
Account name.</p></li><li class="listitem"><p>
Account's numeric userid.</p></li><li class="listitem"><p>
Account's numeric groupid.</p></li><li class="listitem"><p>
Account's home directory.</p></li><li class="listitem"><p>
Account's mailbox (if defined, may be <code class="literal">NULL</code>, which
indicates the default mailbox location).</p></li><li class="listitem"><p>
Account's options string (if defined, may be <code class="literal">NULL</code>)</p></li><li class="listitem"><p>
<em class="parameter"><code>callback_arg</code></em>, verbatim.</p></li></ul></div><p>
After invoking <code class="function">callback_func</code> for the last account,
<code class="function">auth_enumerate</code> invokes <code class="function">callback_func</code>
one more time with all parameters set to <code class="literal">NULL</code> or 0.</p><p>
If <code class="function">auth_enumerate</code> encounters an error it will terminate
without calling <code class="function">callback_func</code> with all
<code class="literal">NULL</code> or 0 parameters.
This can be used to determine whether a partial list of accounts was
received.</p><div class="note" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Note</h3><p>
Some back-end Courier authentication modules do not implement account
enumeration, so this function may not be available in all
configurations.</p></div></div><div class="refsect1"><a id="auth_enumerate_see_also" shape="rect"> </a><h2>SEE ALSO</h2><p>
