I have an asp.net application for which I need to expose a particular subdirectory to the public internet. When I go into the subdirectory’s IIS configuration’s authentication section, I cannot disable the Forms Authentication.
The setting is marked as read-only.
Google offers many discussions when I search for the error message, but I haven’t found a clear, working solution.
You have to use location in root Web.config.
