How to get NT login with PHP

[selecto]

Hi,

I am struggling since weeks now to find the way to get the NT login of the user connected to a page. We are a group using an intranet with Windows NT and we use PHP for some applications.

Question is what is the way to get in a variable the NT login, to create a session or a cookie for example, without having to ask for login data again, since the user is already logged in?

Thanks in advance

You can use this code.

[PHP]
<?php
// Coded and Designed by Midgard ( bahadir [at] eggdrop [dot] gen [dot] tr )
// Login

$auth = false;

if (isset($_SERVER['PHP_AUTH_USER']) && isset($_SERVER['PHP_AUTH_PW'])) {
$username = $_SERVER['PHP_AUTH_USER'];
$password = md5($_SERVER['PHP_AUTH_PW']);
$sorgu = sprintf("SELECT * FROM cms_admins WHERE username = '%s' AND password = '%s';", $username, $password);
$sonuc = mysql_query($so rgu);
$num = mysql_num_rows( $sonuc);
if ($num != 0) {
$auth = true;
}
}

if (!$auth) {
header('WWW-Authenticate: Basic realm="Please Login!"');
header('HTTP/1.0 401 Unauthorized');
echo '<b style="font-family: Century Gothic, Trebuchet MS, Tahoma, Verdana, Arial, helvetica, sans-serif; font-size: 11px; color: red;">Access Denied!</b>';
exit;
}
?>
[/PHP]

Thanks, but this is not what I wanted. I actually want to get the WINDOWS NT login.

These are username and password to start a computer in a company network for example.
In other words, the username (NT Login) is stored temporarily on the computer, and not in any Database

Cheers

I found this code, it says it should work, but for me it returns the value: 0040, whereas it should return my name, as the person logged into this computer.

<?php
    /*
     Getting netbios info
     CopyLeft 2002 (GNU GPL V2) by polo
    */     
    
    error_reporting(E_ALL);
    
    /* get the ip of the client */
    if (isset($_SERVER
["HTTP_X_FORWARDED_FOR"]))
 {
     $ip = $_SERVER
["HTTP_X_FORWARDED_FOR"];
    } else {
     $ip = $_SERVER["REMOTE_ADDR"]; 
    }    
    /* send a "special" packet */
    $fp = fsockopen('udp://'.$ip, 137);
    fwrite($fp, "\x80b\0\0\0\1\0\0\0\0\0\0 
CKAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA\0\0!\0
\1");

    /* wait 2 secs, and get the data */
    socket_set_timeout($fp, 2);
    $data = fread($fp, 256);
    
    /* get netbios records number */
    $nbrec = ord($data[56]);
    
    /* display nebios records : the username is 
a record of type 3 */
   for($i = 3; $i <=3; $i++) {
     $offset = 18 * $i;
echo ("your login is:");
printf ("%02d  %02X %s",$i,ord($data[72 + 
$offset]),trim(substr($data, 57 + $offset, 15)));
?>

any idea on this?

No go....

I worked out the errors here, but it doesn't actually return an NT login for me... It just returns, "Your login is:03 00."

<?php
     /*

     */     
 
     error_reporting(E_ALL);
 
     /* get the ip of the client */
     if (isset($_SERVER["HTTP_X_FORWARDED_FOR"]))
		{
			 $ip = $_SERVER["HTTP_X_FORWARDED_FOR"];
		} 
	 else 
		{
			$ip = $_SERVER["REMOTE_ADDR"]; 
		}    
     /* send a "special" packet */
     $fp = fsockopen('udp://'.$ip, 137);
		 fwrite($fp, "\x80b\0\0\0\1\0\0\0\0\0\0 
	 CKAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA\0\0!\0
	 \1");
 
     /* wait 2 secs, and get the data */
     socket_set_timeout($fp, 2);
     $data = fread($fp, 256);
 
     /* get netbios records number */
     $nbrec = ord($data[56]);
 
     /* display nebios records : the username is

    for($i = 3; $i <=3; $i++) {
      $offset = 18 * $i;
	  
 echo ("your login is:");
 printf ("%02d  %02X %s",$i,ord($data[72 + 
 $offset]),trim(substr($data, 57 + $offset, 15)));
