How to configure pass through authentication except to encoding base64.

Content

hi 

I have tried to configure pass through authentication on OracleServiceCloud.

however,  target group ware could not use base64 encoding.

I would like to configure pass through authentication except to encoding base64.

Is it possible to set up without using base64?

 

----Currently used PHP below--------

<?php

$ptaDataArray = array('p_userid'=>'xxxxx','p_passwd'=>'xxxxx');

$ptaDataString = "";
foreach($ptaDataArray as $key=>$value)
{
 $ptaDataString .= ($ptaDataString === "") ? '' : '&';
 $ptaDataString .= "$key=$value";
}

$ptaDataString = base64_encode($ptaDataString);
$ptaDataString = strtr($ptaDataString, array('+' => '_', '/' => '~', '=' => '*'));
