try restart the application, either in IIS or by a minor edit and saving of web.config file.

If this doesn't help, edit web.config and remove references to Active Directory and Cardspace authentication, if present.

     I had the same error. Moving any references to Active Directory in the web.config worked for me.

I get the same thing, how does one remove the AD reference? I have it inside the "authentication defaultprovider" node and just one "providers" sub-node. Do I just remove the whole higher node or which one?
Thanks
Franco
