Answer 1

您应该检查首次ldap_connect(...)来电的结果。

和

尝试something like this or this验证您的所有连接信息。这对我来说非常有帮助，以确保您拥有正确的帐户信息和LDAP目录信息。

Answer 2

为什么以下行没有端口？

$ldap_server = "10.10.10.10";
$ldap_conn = ldap_connect($ldap_server);

尝试类似下面的内容

 if($authMethod == 0){
    $ldap_server = 'ldap://'.$host.':'.$port;
}else if($authMethod == 1) {
    $ldap_server = 'ldaps://'.$host.':'.$port;
}
$ldap_conn = ldap_connect($ldap_server);

然后检查$ ldap_conn是true还是false或任何其他返回码。端口＃389是简单LDAP的默认值，636是LDAPS。我希望这应该工作:)。干杯!!!!
