Description:
------------
When using svn_import php give a boolean true back. But nothing changed in the repository. When I enter the command as the same user (svn import import_dir repository_url) it works fine.

Reproduce code:
---------------
public function __construct($p_sModuleUrl, $p_sTemplateDir){
		parent::__construct($p_sModuleUrl, $p_sTemplateDir);
		$oAuth= new clsAuthenticate();
		$this->_aUser = $oAuth->getArray();
		svn_auth_set_parameter(SVN_AUTH_PARAM_DEFAULT_USERNAME, $this->_aUser["svn_user"]);
		svn_auth_set_parameter(SVN_AUTH_PARAM_DEFAULT_PASSWORD, $this->_aUser["svn_pass"]);
		$this->_sLocalPath = realpath('/usr/local/www/dev/'.$this->_aUser["svn_user"].'/common/');
		$this->_sRepository = "file:///usr/local/svn/repository/insite";
		$this->_sDirStructure = realpath('/usr/local/svn/project_layout');
	}
	
	public function getAjaxAddsvn(){
		$oProject = new doProjects();
		$oInput = clsInput::singleton();
		$nProject = $oInput->get('project');
		$oProject->loadById($nProject);
		if (svn_import('/usr/local/www/dev/ruud/maximaal', $this->_sRepository."/test123", false)){
			return $this->getMessage("Subversion project created");
		}else{
			return $this->getMessage("Subversion project creation FAILED!");
		}
	}

Expected result:
----------------
Directory added to the repository.

Actual result:
--------------
boolean true. Nothing changed in repository.
