I am running DotNetNuke Version: 04.09.02.  About 6 months ago I enabled ActiveDirectory Authentication and it has been working fine.  However I now need to make some adjustments so I went to “Admin – Authentication” and I get the error below when the page comes up.  I upgraded to ActiveDirectory_01.00.05 but I still get the error.

Active Directory users can still login so it looks like everything is working, I just can’t get to the page to make adjustments.  I’m also trying to setup child portals to allow ActiveDirectory users to login but I can’t get to this page in my child portals either.  When I turn off “ActiveDirectory” in the Host settings I can get to this page.  I’m running this on IIS7 but I haven’t made any changes from when I first installed it that I can remember.

Thanks for any assistance.

I am not but I had tried it and followed all the steps in the directions.  Whenever I change the web.config file and try to use impersonation I get this error:

HTTP Error 500.19 - Internal Server Error
The requested page cannot be accessed because the related configuration data for the page is invalid.
 

I have it setup like this in web.config with a account with the same permissions as NETWORK SERVICE:

<identity impersonate="true" userName="username" password="password" />
            <authentication mode="Windows">
            </authentication>

Thanks.
