Integrating wp-login fields into template

I have been looking everywhere for a solution for my need, but so far found nothing. I was trying to have the wp-login filelds integrated in my template, so users can have a little box where to put their username and password and access the private areas of the blog without messing with the wp-login page.

Anyone has seen this done? Plugin? Tutotial? Any place to get the hook?

Thanks in advance!
