Lino i have been using Forms Auth with AD and its been working well for me
after some struggles with it(What i had to change
in the MSDN code was that it couldn't retrieve GROUPS but it can
authenticate)
HAve you set the right Authentication mode in the IIS for the Directory..
Make sure it has Windows Auth and try again..
If problem still persist let me know..
