[Owncloud] OC5.0.7 and user_saml 0.3 issue

[Nikola Garafolic]

I have trouble setting it up.
I am using simplesamlphp 1.8.2 with sp_source set as default-sp.
I configured ssp_path to point to /usr/share/simplesamlphp/ - where 
simplesamlphp is located on Centos 6.4
When I enable user_saml app, I get only http 500 errors. In httpd logs I 
see this:

  [error] [client 192.168.4.9] PHP Fatal error:  Class 
'SimpleSAML_Auth_Simple' not found in 
/var/www/html/owncloud/apps/user_saml/user_saml.php on line 53

user_saml.php file is including include_once 
$this->sspPath."/lib/_autoload.php"; but there is no mention of class 
SimpleSAML_Auth_Simple. So i tried including include_once 
$this->sspPath."/lib/SimpleSAML/Auth/Simple.php"; instead because it 
contains missing class, but still nothing. What is the problem here?

Regards,
