Does anyone know of a way to disable or remove the Windows authentication from custom forms? We have a mixed environment with a large quantity of Macs and iOS devices along with several custom web forms. We removed the windows authentication dialog that drops down from Safari/FireFox using a hack of login.aspx found here in the forums but the login.aspx page and associated code doesn't exist on our custom forms. We have Windows Auth off in IIS and off in the forms and yet the darn authentication dialog keeps showing up so that it appears a user has to log in twice.
Any help would be appreciated.
