Flex FileReference doesn't work with NTLM authentication

We use the FileReference component to upload file in Flex. But开发者_StackOverflow if the application is deployed within an environment having NTLM authentication (Windows Integrated Authentication), the upload capability will not work, and each time a message box will be popup asking the user to input credentials.

I've queried some resource from internet and it seems this is a bug of FileReference component.

Is there any solution for this issue? Thanks.

Sorry, it isn't possible with FileReference

Also, I think it's important to distinguish that this isn't a bug it's based on known conditions within the client OS and browser - this isn't something that Adobe could fix if they wanted to.
