Embed Report or Tile in CRM Dynamics

Hi People, I'm trying to embed a report in Dynamics CRM. I tried loading an HTML web resource that use the iframe code to publish to Web and ready this works well. This is what I get:

then the problem is that I don't want to embed a public report, I want to achieve the same result in the picture but embedding a report that use authentication, ie, one that is not publish to web.

anyone know if this is possible in Dynamics CRM? every comment is welcome, thanks...
