Problems connecting to a basicHttpBinding endpoint with security mode=“None”

问题

Trying to create an framework 4.0 WCF basicHttp service hosted by IIS (6) that is completely unauthenticated. Once deployed, I can successfully retrive the WSDL via a browser.

However whenever I try and connect to it via WCF Test Client or via a visual studio generated proxy, I'm getting "The server has rejected the client credentials.".

This still occurs when I add <security mode="None"/>, but my understanding is that this is the default anyway ...

In the IIS virtual directory properties I only have anonymous ticked, and in the web.config file <authentication mode="None"/> is set as well.

Any ideas?

回答1:

Seems like the IIS site has anonymous authentication disabled. Check out this article on IIS 6 anonymous access configuration.

回答2:

Turns out that the source of the exception was from an immediate attempt to connect to a downstream tcp service. As a workaround I ended up creating a plain jane webservice wrapper which successfully connects to the downstream service fine using a domain account specified in the <identity impersonate="true" userName=".." password=".." />.

Note, I've added a related question asking why one works and the other doesn't.
