I am publishing a form to a SharePoint site.  The form has buttons configured to allow access to different views based on user roles assigned to AD groups.  When I try to open the form, it fails with the message thatthe user name or group membership cannot be verified because of the form's security settings.  I have tried publishing it with the automatically detect option selected, and with domain security option selected.  Suggestions?

If you are still getting the security message in those situations, then you are likely stuck making a full-trust form. Otherwise there's something wrong about how you are doig user roles or how your SharePoint site or Exchange server is set up. Unfortunately, I don't have the background to be able to help you here, but hopefully this at least gives you some places to look.
