Which authentication mode of basichhtpbinding can be used to secure a WCF Service using Streaming?

Question

Hi all,

Details about my service:

1. A file upload service
2. Transfermode is set to stream
3. Service is hosted in IIS 7.

I need to provide secuirty to my service. I have tried with ntlm and windows secuirty.I was getting the following error when i am trying to secure my service

"HTTP request streaming cannot be used in conjunction with HTTP authentication. Either disable request streaming or specify anonymous HTTP authentication."

I have found a description stating that: Description:

You can't do transport auth. with streaming. If you have to use HTTP request streaming, you'll have to run without security.

So i wish to know how can i secure my service? Which secuirty mode can i use with basichttpbinding?Can anyone pls help me on this?
