How to use adminer without password basing on login-password-less plugins

    Hello,
    I want to use adminer without password.
    I uploaded adminer-4.7.7-en.php file and finding login-password-less plugin
    I create file plugins/login-password-less.php with content :
    SEMrush



    <?php
    class AdminerLoginPasswordLess {
        /** @access protected */
        var $password_hash;
      
        /** Set allowed password
        * @param string result of password_hash
        */
        function __construct($password_hash) {
            $this->password_hash = $password_hash;
        }
        function credentials() {
            $password = get_password();
            return array(SERVER, $_GET["username"], (password_verify($password, $this->password_hash) ? "" : $password));
        }
      
        function login($login, $password) {
            if ($password != "") {
                return true;
            }
        }
    }
    PHP:


    and reading https://www.adminer.org/plugins/#use I created file adminer.php, which is
    located in one dir with adminer-4.7.7-en.php and I created new apache host pointed at this file.
    <?php
    function adminer_object() {
        // required to run any plugin
        include_once "./plugins/login-password-less.php";
        // autoloader
        foreach (glob("plugins/*.php") as $filename) {
            include_once "./$filename";
        }
        $plugins = array(
            // specify enabled plugins here
            new AdminerLoginPasswordLess(hash("md5", 'my_sql_user_password')),
            //Is the selected "md5" method valid ?
        );
        return new AdminerPlugin($plugins); // I am not sure which class is it and where it is defined ?
    }
    // include original Adminer or Adminer Editor
    include "./adminer-4.7.7-en.php";  // encoded file I uploaded
    ?>  
    PHP:
    But I got error :

    Fatal error: Uncaught Error: Class 'AdminerPlugin' not found in /mnt/_work_sdb8/wwwroot/lar/local_adminer/adminer.php:32 Stack trace: #0 /mnt/_work_sdb8/wwwroot/lar/local_adminer/adminer-4.7.7-en.php(1654): adminer_object() #1 /mnt/_work_sdb8/wwwroot/lar/local_adminer/adminer.php(36): include('/mnt/_work_sdb8...') #2 {main} thrown in /mnt/_work_sdb8/wwwroot/lar/local_adminer/adminer.php on line 32
    Code (markup):
    Which class AdminerPlugin is it and where it is defined ?
    How to fix this issue?
    Thanks!

    In source version of the site I found file plugin.php with AdminerPlugin class implementation.
    I moved this file under plugins directory.
    In plugins/login-password-less.php I added reference to plugins/plugin.php file and added debugging info :

    <?php
    /** Enable login for password-less database
    * @link https://www.adminer.org/plugins/#use

    * @license https://www.gnu.org/licenses/gpl-2.0.html GNU General Public License, version 2 (one or other)
    */
    include_once "./plugins/plugin.php";
    class AdminerLoginPasswordLess {
        /** @access protected */
        var $password_hash;
        /** Set allowed password
        * @param string result of password_hash
        */
        function __construct($password_hash) {
            $this->password_hash = $password_hash;
            debToFile('-2 AdminerLoginPasswordLess->__construct:$this->password_hash::'.$this->password_hash);
            // That is debugging method appending  string into text file
        }
        function credentials() {
            $password = get_password();
            debToFile('-3 AdminerLoginPasswordLess->credentials:$password::'.$password);
            // That is debugging method appending  string into text file
            return array(SERVER, $_GET["username"], (password_verify($password, $this->password_hash) ? "" : $password));
        }
        function login($login, $password) {
            debToFile('-4 AdminerLoginPasswordLess->login:$login::'.$login);
            if ($password != "") {
                debToFile('-5 TRUE AdminerLoginPasswordLess->login:$login::'.$login);
            // That is debugging method appending  string into text file
                return true;
            }
            debToFile('-5 false AdminerLoginPasswordLess->login:$login::'.$login);
        }
    }
    PHP:
    and in adminer.php I added debugging line:

    
        $plugins = array(
            new AdminerLoginPasswordLess(hash("md5", 'm8y2s8q&L')),
        );
        debToFile('-1After:AdminerLoginPasswordLess');
    
    PHP:
    I loggin file I see:

    <pre>::-2 AdminerLoginPasswordLess->__construct:$this->password_hash::c61d49aaab35ca428e60d764ff05159d</pre>
    <pre>::-1After:AdminerLoginPasswordLess</pre>
    Code (markup):
    It means that methods credentials and login of AdminerLoginPasswordLess class are not triggered.
    I run in browser as :
    
    http://local-adminer.com/?username=mysql_login_user
    
    Code (markup):
    or
    http://local-adminer.com
    Code (markup):
    // host in apache config
    and I have no errors, but I still have to enter password for mysql_login_user.
    Did I miss some options/plugins?
