LDAP : SambaMungedDial Syntax

[Yohann Fourteau]

So for people who want to extract info from sambaMungedDial attribute, I ve done
a little script (in php) :
----------------------------------------------
<?
function hexbin($hex){
   $bin='';
   for($i=0;$i<strlen($hex);$i+=2)
     $bin.=chr(hexdec(substr($hex,$i,2)));
   return $bin;
}

$res=ldap_connect("localhost");
ldap_bind($res);
$dn="the dn";
$ret=ldap_read($res,$dn,"objectclass=*",array("sambamungeddial"));
$entries = ldap_get_entries($res, $ret);
$str=$entries[0]["sambamungeddial"][0];
ldap_close($res);


$string=base64_decode($str);
$len=strlen($string);
$noField=0;
$i=0;
while($i<$len)
{
    if ($string[$i+6]=='C' && $string[$i+8]=='t' && $string[$i+10]=='x')
    {
        if ($noField==0)
            $first=$i;
        $fieldNameLen=ord($string[$i]);
        $field[$noField]["name"]="";
        $field[$noField]["value"]="";
        for($j=$i+6;$j<$i+6+$fieldNameLen;$j+=2)
        {
            $field[$noField]["name"].=$string[$j];
        }
        $fieldValueLen=ord($string[$i+2]);
        for($j=$i+6+$fieldNameLen;$j<$i+6+$fieldNameLen+$fieldValueLen;$j++)
        {
            $field[$noField]["value"].=$string[$j];
        }
        $noField++;
        $i=$i+6+$fieldNameLen+$fieldValueLen;
    }
    else
        $i++;
}

$stringFields=array("CtxMinEncryptionLevel","CtxWorkDirectory","CtxNWLogonServer","CtxWFHomeDir","CtxWFHomeDirDrive","CtxWFProfilePath","CtxInitialProgram","CtxCallbackNumber");
foreach($field as $index => $fi)
{
    if (in_array($fi["name"],$stringFields))
    {
        $field[$index]["value"]=hexbin($fi["value"]);
    }
}

var_dump($field);
// no idea what it is, the rest is space caracters.
echo ord($string[$first-4])."\n";
echo ord($string[$first-2])."\n";
?>
--------------------------------------------

I'm writing another script (in php) which integrate data into that attribute.
