Re: Windows Authentication in DNN - Authentication Module

Tom,

yes, always. At least, it looks like that.

Please check your IIS/NTFS settings again. WindowsSignin.aspx should not allow anonymous access.

There should be a web.config file in this folder (/DesktopModules/AuthenticationServices/ActiveDirectory) with the following contents:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
   <location path="WindowsSignin.aspx">
      <system.webServer>
         <security>
            <authentication>
               <windowsAuthentication enabled="true" />
               <anonymousAuthentication enabled="false" />
            </authentication>
         </security>
      </system.webServer>
   </location>
</configuration>

Happy DNNing!
Michael

Re: Windows Authentication in DNN - Authentication Module

Thanks again Micheal.
Yes I do have Anonymous Authentication set as Disabled (only Forms Authentication and Windows Authentication are enabled for that file). And my web.config in that folder looks like yours.

I just re-installed the extension and went through everything again, and I'm back where I was before:
- If I just browse to the site address, I don't get automatically logged in ( I just see the homepage with a Login button))
- If I browse directly to the windows signin page while on the Windows network, I will get automatically logged in to the site (as Windows user)
- If I browse to a page which is restricted to registered users only, I get re-directed to the Login Page (which has tabs for Standard log in or Windows log in), where I can manually log in as either Standard or Windows user.
- There are two Users in the site (besides admin/host) The two Users (myself and one co-worker) were created automatically by browsing to the WindowsSignin page while on the Windows network, and have name/email, etc information pulled from AD )

So it seems like the auto re-direct to the windows login is what isn't working. Do you know how that works?
Do you have the site's default document set to anything? Any other ideas why it isn't working?

I suppose it could have to with the fact that I'm running DNN 9 and maybe the module hasn't been made to work with it yet. And it seems to have very little support.
But I feel so close to getting it to work I dont want to give up just yet.

Thank you

Tom

Re: Windows Authentication in DNN - Authentication Module

Tom,

I was looking at my web.config file to find an answer, what I found as relevant are these entries:

<system.webServer>
   ...
   <modules>
      ...
      <add name="Authentication" type="DotNetNuke.Authentication.ActiveDirectory.HttpModules.AuthenticationModule, DotNetNuke.Authentication.ActiveDirectory" />
      ...
   </modules>
   <handlers>
      ...
      <add name="LogoffHandler*" path="Logoff.aspx" verb="*" type="DotNetNuke.Services.Authentication.LogOffHandler, DotNetNuke" preCondition="integratedMode" />
      ...
   </handlers>
   ...
</system.webServer>
<system.web>
   ...
   <httpModules>
      <!-- add name="Authentication" type="DotNetNuke.HttpModules.AuthenticationModule, DotNetNuke.HttpModules.Authentication" / -->
      ...
      <remove name="FormsAuthentication" />
      <add name="FormsAuthentication" type="System.Web.Security.FormsAuthenticationModule" />
      ...
      <add name="Authentication" type="DotNetNuke.Authentication.ActiveDirectory.HttpModules.AuthenticationModule, DotNetNuke.Authentication.ActiveDirectory" />
   </httpModules>
   <httpHandlers>
      ...
      <!-- This adds legacy support for the Logoff page -->
      <add verb="*" path="Logoff.aspx" type="DotNetNuke.Services.Authentication.LogOffHandler, DotNetNuke" />
   </httpHandlers>
   ...
<system.web>
...
<!-- Forms or Windows authentication -->
<authentication mode="Forms">
   <forms name=".DOTNETNUKE" protection="All" timeout="60" cookieless="UseCookies" />
</authentication>
<!--
<identity impersonate="true" userName="DOMAIN\serviceuser" password="password" />
   <authentication mode="Windows">
</authentication>
-->
...
<authentication defaultProvider="ADSIAuthenticationProvider">
   <providers>
      <clear />
      <add name="ADSIAuthenticationProvider" type="DotNetNuke.Authentication.ActiveDirectory.ADSI.ADSIProvider, DotNetNuke.Authentication.ActiveDirectory" providerPath="~\Providers\AuthenticationProviders\ADSIProvider\" />
   </providers>
</authentication>
...
<location path="DesktopModules/AuthenticationServices/ActiveDirectory/WindowsSignin.aspx">
   <!-- Disable Forms Authentication -->
   <formsAuthenticationWrapper enabled="false" />
   <system.webServer>
      <security>
         <!-- Enable IIS Windows authentication for the login page -->
         <authentication>
            <windowsAuthentication enabled="true" />
            <anonymousAuthentication enabled="false" />
         </authentication>
      </security>
   </system.webServer>
</location>

Hope that helps.

Happy DNNing!
Michael

Re: Windows Authentication in DNN - Authentication Module

Thanks so much Michael. I was actually thinking to ask about your web.config. I'll take a look and compare mine and see whether I can get this working better. Will let you know.
Thanks again, I really appreciate it.
