more example from mariadb server:

here more info about how to use dialog and client:
https://github.com/MariaDB/server/blob/10.1/plugin/auth_dialog/dialog.c
/*
This plugin performs a dialog with the user, asking questions and
reading answers. Depending on the client it may be desirable to do it
using GUI, or console, with or without curses, or read answers
from a smartcard, for example.
To support all this variety, the dialog plugin has a callback function
>>>>>"authentication_dialog_ask"<<<<<. If the client has a
>>>>>function of this name
dialog plugin will use it for communication with the user. Otherwise
a default implementation will be used.

Description:
------------
Hi guys, i'm testing mysql connect with a mariadb server using a dialog auth plugin (server
side)
i didn't found functions to execute dialog with server
a full example of what i want but using heidisql can be found here:
http://www.heidisql.com/forum.php?t=9752

here the php files (download only .php files):
https://github.com/rspadim/server/blob/otp_plugin/plugin/auth_otp/
here the today output using mysql_connect: (using otp_auth_example.php php file)
==============================

Test script:
---------------
https://github.com/rspadim/server/blob/otp_plugin/plugin/auth_otp/
download all .php files
otp_auth_example.php
at mariadb server:
INSTALL PLUGIN three_attempts SONAME 'dialog_examples.so';
CREATE USER test_dialog IDENTIFIED VIA three_attempts USING 'SECRET';
try to connect using username = test_dialog, and password='SECRET'
Expected result:
----------------
implement a new feature of dialog connection
three functions must be implemented for <mysql> and <mysqli> extension:
mysql_auth_dialog_received()
mysql_auth_dialog_receive()
mysql_auth_dialog_send()
and maybe at mysql_connect we will need a parameter to call a mysql function, for example
$link = mysql_connect($HOST, $USER, $PASSWORD);
if(mysql_auth_dialog_received($link)){
$tmp=mysql_auth_dialog_receive($link); /*
array(type=>'pass/text',message=>'any message') */
mysql_auth_dialog_send($link,"any message");
}
if($link){
// ok good connection
}else{
// die("can't connect");
}
-------------
with mysqli we could use mysqli_init, mysqli_options, mysqli_realconnect
$db = mysqli_init();
$test = $db->options(MYSQLI_DIALOG_FUNCTION,function(){});
or
$test = $db->options(MYSQLI_DIALOG_FUNCTION,"an_callback_function");
function an_callback_function($db,$type,$message){
return true; /* wait other message */
return false; /* disconnect */
mysqli_auth_dialog_send($db,"message");
}
------------
PDO:
$dbh = new PDO("mysql:host=$HOST;port=$HOST_PORT;dbname=$DB", $USER, $PASSWORD, array(
"MYSQL_DIALOG_AUTH_CALLBACK_FUNCTION" => function(){} ));
or
$dbh = new PDO("mysql:host=$HOST;port=$HOST_PORT;dbname=$DB", $USER, $PASSWORD, array(
"MYSQL_DIALOG_AUTH_CALLBACK_FUNCTION" => "an_callback_function" ));
function an_callback_function($db,$type,$message){
return true; /* wait other message */
return false; /* disconnect */
$db->mysqli_auth_dialog_send($db,"message");
}
Actual result:
--------------
no client side auth dialog interface
