If there is a userID and/or rule specified; the usual password and access checks will be applied and a failure will give an "Authentication Required" reply.</p> <p>So if a userID appears in the database of more than one module; or if a valid <code class="directive"><a href="../mod/core.html#require">Require</a></code> directive applies to more than one module; then the first module will verify the credentials; and no access is passed on; regardless of the <code class="directive">AuthAuthoritative</code> setting.</p> <p>A common use for this is in conjunction with one of the database modules; such as <code class="module"><a href="../mod/mod_auth_dbm.html">mod_auth_dbm</a></code>, <code>mod_auth_msql</code>, and <code class="module"><a href="../mod/mod_auth_anon.html">mod_auth_anon</a></code>. These modules supply the bulk of the user credential checking; but a few (administrator) related accesses fall through to a lower level with a well protected <code class="directive"><a href="#authuserfile">AuthUserFile</a></code>.</p> <p>By default control is not passed on and an unknown userID or rule will result in an "Authentication Required" reply. Not setting it thus keeps the system secure and forces an NCSA compliant behaviour.</p> <div class="warning"><h3>Security</h3> <p>Do consider the implications of allowing a user to allow fall-through in his .htaccess file; and verify that this is really what you want; Generally it is easier to just secure a single .htpasswd file, than it is to secure a database such as mSQL.
