Some applications, such as the Netscape web server, rely upon the string being NULL-appended, so if you are having trouble using DBM files interchangeably between applications this may be a part of the problem.</p> <p>A perl script called <code class="program"><a href="../programs/dbmmanage.html">dbmmanage</a></code> is included with Apache. This program can be used to create and update DBM format password files for use with this module.</p></div></div><div class="bottomlang"><p><span>Available Languages: </span><a href="../en/mod/mod_authn_dbm.html" title="English"> en </a> |<a href="../ja/mod/mod_authn_dbm.html" hreflang="ja" rel="alternate" title="Japanese"> ja </a> |<a href="../ko/mod/mod_authn_dbm.html" hreflang="ko" rel="alternate" title="Korean"> ko </a></p></div><div id="footer"><p class="apache">Copyright 2008 The Apache Software Foundation.<br />Licensed under the <a href="http://www.apache.org/licenses/LICENSE-2.0">Apache License, Version 2.0</a>.</p><p class="menu"><a href="../mod/">Modules</a> | <a href="../mod/directives.html">Directives</a> | <a href="../faq/">FAQ</a> | <a href="../glossary.html">Glossary</a> | <a href="../sitemap.html">Sitemap</a></p></div></body></html>⌨️ 快捷键说明
