Most succinctly, my question is whether an ASP.NET 4.0 app running under IIS 7 integrated mode should be able to honor this portion of my Web.config file:
<location path="auth/windows">
<system.webServer>
<modules>
<remove name="FormsAuthentication"/>
</modules>
</system.webServer>
</location>
I'm experimenting with mixed mode authentication (Windows and Forms - I know there are other questions on S.O. about the topic). Using IIS Manager, I've disabled Anonymous authentication to auth/windows/winauth.aspx, which is within the location
path above. I have Failed Request Tracing set up to trace various HTTP status codes, including 302s.
When I request the winauth.aspx page, a 302 HTTP status code is returned. If I look at the request trace, I can see that a 401 (unauthorized) was originally generated by the AnonymousAuthenticationModule. However, the FormsAuthenticationModule converts that to a 302, which is what the browser sees. So it seems as though my attempt to remove that module from the pipeline for pages in that
path isn't working. But I'm not seeing any complaints anywhere (event viewer, yellow pages of death, etc.) that would indicate it's an invalid configuration. I want the 401 returned to the browser, which presumably would include an appropriate WWW-Authenticate header.
A couple of other points: a) I do have <authentication mode="Forms"> in my Web.config, and that is what the 302 redirects to; b) I got the "name" of the module I'm trying to remove from the inetserv\config\applicationHost.config
file.
Anyone had any luck removing modules in this fashion?
Thanks much,
Donnie
