FIM 2010 R2 and Sharepoint 2010

Hi,

I recall reading that FIM 2010 R2 registration and reset websites run directly on top of IIS (they are their own sites) and don't use SharePoint - unlike the actual FIM admin portal which uses either WSS or 2010 Foundation. (http://social.technet.microsoft.com/Forums/en/ilm2/thread/3915dd3a-4497-4a9c-a9dd-3dfddf84def9)

So did I hear in error somewhere that FIM 2010 R2 can be integrated into an existing Sharepoint 2010 farm?

Please could someone clarify this.

Thank you,

SK
