pentaho 5.0.1 - authentication via url parameters for iframe

Hi,

We work on a web java app that embedded pentaho reports through iframes:

<iframe width="1050" height="580" src="http://localhost:8085/pentaho/api/repos/:public:reporte_ejecucion.prpt/generatedContent?userid=admin&password=password" name="previewFrame">
</iframe>

when the page load it ask for user and password, seems pentaho server does not recognize the parameters.

On pentaho 4.8 this work perfect. Could have changed the parameters in this release?

I read the following guide but does not explain how pass user/password parameters: http://infocenter.pentaho.com/help50...put_types.html

thanks,

Carlos
