So I installed 4.3 from the install package, got it running without issue, but when I tried enabling AD auth, the Admin-Authentication page is disabled and tells me "The default authentication provider specified in web.config is not configured properly.  Authentication settings are disabled.".  I have done the web.config modifications neccesary for AD auth (uncommenting the httpModule "Authentication", not touching the "Authentication" tag...) I checked the web.config and followed the path to the ADSI authentication provider, and sure enough, the "Providers\AuthenticationProviders" folder was missing, I'm guessing that's not included in the install package.  I downloaded the source package and tried adding that folder but it still does not work.  I even compiled the vb for ADSI Auth into a .dll but the authentication page still does not work.

I had hoped to get AD auth running without touching any code other than web.config, which is why I used the install package.  Is this impossible without using the entire source package?  No customization has been done at this point, so scrubbing it and starting from source isn't that painful, but before I do I want to make sure that's my only and/or best option.  I'm also assuming that the same steps outlined for getting AD passthrough authentication working in 3.x apply to 4.3?
