Using forms authentication to control security access to msolap.asp. Is it possible using ASP.NET?

Hi:
My organization has developed a portal made in ASP.NET (C#). This portal
is open for Internet, and we decide to use Forms Authentication to validate
user and password. This authentication doesn't seems to be valid (or not)
when using MSOLAP.ASP. It's a big security risk for me leave the MSOLAP.ASP
page open "to the world", and it's really boring to the user tip a logon
information again, and also the extra effort to keep a second user database
(in Windows or in another place) is tedious, error prone and inneficient.
Is there some way that force MSOLAP.ASP to use Forms Authenticatiom?
Debugging this ASP page, I have some suspicious that cookies and another
informations are sent with MSOLAP request, better saying, some browser
informations are sent within ActiveX request.
But I really can't find any usefull to validate the user. Session is
unavaiable for me, I believe that the reason is that my application is
developed is ASP.NET.
Is there some port of MSOLAP.ASP for .Net platform? Is it possible to
use Forms Authentication? Did anyone had the same problem?

Thanks,
Ravi.
