Does digMeta work in a mixed AD and DNN Forms authentication environment?

In my site, internal users are authenticated via AD and external users through standard DNN forms authentication.  I have tried using metaPost and it does not appear to work with AD authentication enabled.

I gave the demo a try.  It does not work out of the box.  The issue appears to be with the AD provider hijacking the request. 

With AD set to perform auto-login, the call to the digNuke API by the client is 'interrupted' by an NT Authentication Challenge Response.  So... I went to digNuke directory and removed the Windows Authentication mechanism.  That did get past the first road-block and the client is now able to communicate with the API, but the response for ANY XML-RPC Post call to the ashx receives the HTML response that you receive from a GET on the ashx. 

I assume that this is caused by something in DotNetNuke.Authentication.ActiveDirectory and the htmlmodule that is installed via web.config ().  I haven't been able to locate the source for this assembly to see what is going on.

Hi,

In your web.config, do you have an entry for formAuthentication - cookieless?  If so, what is it set to?

Thanks,

Mike

Here is the forms authentication entry...

    <!-- Forms or Windows authentication -->
    <authentication mode="Forms">
      <forms name=".DOTNETNUKE" protection="All" timeout="60" cookieless="UseCookies" />
    </authentication>
