SugarCRM 5.5.0 Issues Connecting to SOAP

[sunnysidesounds]

For some reason I can't connect through the SOAP API anymore since I upgraded to 5.5.0. I have tried a simple example on the wiki here: http://www.sugarcrm.com/wiki/index.p...alls_using_PHP

Here is my code I used:

 <?php
 
require_once('nusoap.php');
$client = new nusoap_client('https://crm.examplesite.edu/soap.php?wsdl',true);
 
 $auth_array = array(
    'user_auth' => array(
      'user_name' => 'admin',
      'password' => md5('mypassword'),
    )
 ); 
 
  $login_results = $client->call('login',$auth_array);
 
  $session_id =  $login_results['id'];
 
  $user_guid = $client->call('get_user_id',$session_id);
 
  printf("\n".$auth_array['user_auth']['user_name'].' has a GUID of '  . $user_guid . "\n\n");
?>  

When I run this script it returns this:

stdClass Object ( [id] => -1 [error] => stdClass Object ( [number] => 10 [name] => Invalid Login [description] => Login attempt failed please check the username and password ) )

I also ran a similar script that just outputs: admin has a GUID of -1

Could you guys give my any suggestions on how or where I can resolve this issue. Is their an updated examples to connect to SugarCRM 5.5.0? Is there a different approach to connecting to the 5.5.0 version of SOAP? What does it mean when it returns a negative GUID for admin?

I had this problem once before when we upgraded Sugar. I couldn't resolve the issue and ended up reinstalling Sugar. This time I am trying to prevent from doing this. I've also tested this through my local dev environment with no issues connecting.

Thanks in advance for any help

Change to
<?php
$client = new SoapClient(null,
array('location' => 'https://crm.examplesite.edu/soap.php',
'uri' => 'http://www.sugarcrm.com/sugarcrm',
'soap_version' => SOAP_1_1,
'trace' => 1,
'exceptions' => 0
));
$auth_array = array(
'user_name' => 'admin'',
'password' => md5('mypassword'),

);

$login_results = $client->login($auth_array,"test");
$session_id = $login_results->id;
$user_guid = $client->call('get_user_id',$session_id);
printf("\n".$auth_array['user_auth']['user_name'].' has a GUID of ' . $user_guid . "\n\n");
?>
