How to Use SSO with vitger crm and owncloud:

I am implementing a SSO in Vtiger crm and Owncloud (with SimpleSAMLphp)

I used this tutorial :

But I ‘am blocked in this step: In saml20-sp-remote.php:

$metadata['http://ift.tt/1NxchDv'] = array(
'AssertionConsumerService' => 'http://ift.tt/1R6556S
  http://ift.tt/1NxchDx',
'NameIDFormat' => 'urn:oasis:names:tc:SAML:2.0:nameid-format:email',
 'simplesaml.nameidattribute' => 'test',
 'simplesaml.attributes' => FALSE,
 'ForceAuthn' => FALSE,
 'SingleLogoutService' => 'http://ift.tt/1R6556S    
 http://ift.tt/1R6556U',
 );

How can I configure?
