  32 <h3>Summary</h3>
  33
  34     <p>This module allows extended authentication providers to be created
  35     within the configuration file and assigned an alias name.  The alias
  36     providers can then be referenced through the directives
  37     <code class="directive"><a href="../mod/mod_auth_basic.html#authbasicprovider">AuthBasicProvider</a></code> or
  38     <code class="directive"><a href="../mod/mod_auth_digest.html#authdigestprovider">AuthDigestProvider</a></code> in
  39     the same way as a base authentication provider.  Besides the ability
  40     to create and alias an extended provider, it also allows the same
  41     extended authentication provider to be reference by multiple
  42     locations.</p>
