mysql — ejabberd внешняя аутентификация php sqlserver

У меня есть сервер ejabberd 15.03 в виртуальной машине CentOS, и мне нужно реализовать метод внешней аутентификации с php для SQL-сервера.
Официальная документация показывает пример php / mysql
php / mysql внешняя аутентификация

Есть ли способ изменить этот пример на php / sqlserver и такие функции, как mysql_ping.

Вот пример, который я написал и поместил в / opt / auth /, и настроил ejabberd.yml для выполнения как внешнюю аутентификацию.

$auth = new JabberAuth();
$auth->dbhost = "hostIP";
$auth->dbuser = "user";
$auth->dbpass = "pass";
$auth->dbbase = "databaseName";$auth->play(); // We simply start process !

class JabberAuth {
var $dbhost;
var $dbuser;
var $dbpass;
var $dbbase;

var $debug      = false;                      /* Debug mode */
var $debugfile  = "/opt/auth/log/pipe-debug.log";  /* Debug output */
var $logging    = false;                      /* Do we log requests ? */
var $logfile    = "/opt/auth/log/pipe-log.log" ;   /* Log file ... */
/*
* For both debug and logging, ejabberd have to be able to write.
*/

var $jabber_user;   /* This is the jabber user passed to the script. filled by $this->command() */
var $jabber_pass;   /* This is the jabber user password passed to the script. filled by $this->command() */
var $jabber_server; /* This is the jabber server passed to the script. filled by $this->command(). Useful for VirtualHosts */
var $jid;           /* Simply the JID, if you need it, you have to fill. */
var $data;          /* This is what SM component send to us. */

var $dateformat = "M d H:i:s"; /* Check date() for string format. */
var $command; /* This is the command sent ... */
var $mysock;  /* MySQL connection ressource */
var $stdin;   /* stdin file pointer */
var $stdout;  /* stdout file pointer */

Это не сделало никакой ошибки PHP. Но в ejabberd.log я всегда получаю
‘скрипт extauth внезапно завершился с причиной’ нормальной ‘
‘

Это отчет о сбое в crash.log

Кажется, это ошибка неправильной конфигурации.
Это то, что я добавил в ejabberd.yml
