<h3>Summary</h3>

    <p>This module allows extended authentication providers to be created 
    within the configuration file and assigned an alias name.  The alias 
    providers can then be referenced through the directives 
    <code class="directive"><a href="../mod/mod_auth_basic.html#authbasicprovider">AuthBasicProvider</a></code> or 
    <code class="directive"><a href="../mod/mod_auth_digest.html#authdigestprovider">AuthDigestProvider</a></code> in
    the same way as a base authentication provider.  Besides the ability
    to create and alias an extended provider, it also allows the same 
    extended authentication provider to be reference by multiple 
    locations.</p>

    <p>The example below creates two different ldap authentication 
    provider aliases based on the ldap provider.  This allows
    a single authenticated location to be serviced by multiple 
    ldap hosts:</p>
