Hy,

I've got the same problem as my previous posters: "Autologon does not work but login works when calling the windowssignin.aspx directly".

I'm really not sure what I'm doing wrong so I'd like to state a list of all settings that i think that need to be set:

1. IIS: anonymous access to the windowssingin.aspx is turned OFF, Integrated windows-authentication is turned ON
    
2. The site is running in the local intranet zone. (at least on the clients i try to be logged in automatically)
    
3. web.config.
   In there i have following configuration:
   3.1;uncommented line: <!-- add name="Authentication" type="DotNetNuke.HttpModules.AuthenticationModule, DotNetNuke.HttpModules.Authentication" / --> the line stated above is NOT showing up in my web.config.
   3.2: provider:
   <providers>
           <clear />
           <add name="ADSIAuthenticationProvider" type="DotNetNuke.Authentication.ActiveDirectory.ADSI.ADSIProvider, DotNetNuke.Authentication.ActiveDirectory" providerPath="~\Providers\AuthenticationProviders\ADSIProvider\" />
   </providers>
   3.3: Authentication
   <authentication mode="forms">
         <forms name=".DOTNETNUKE" protection="All" timeout="60" cookieless="UseCookies" />
       </authentication>
       <identity impersonate="true" userName="XXXX" password="XXXXX" /> // this is needed for security reasons
    
4. Autologin-Range: I tried multiple variations here. But it does not work for a single ip either:
   4.1; 192.168.1.12 //does noat work
   4.1: The final solution should look like this in my case: 192.168.1.1-192.168.1.254;192.168.3.1-192.168.3.254;192.168.6.1-192.168.6.254;192.168.7.1-192.168.7.254;192.168.9.1-192.168.9.254;192.168.12.1-192.168.12.254
    

Version INFO: DNN: 04.09.01, AD Provider 01.00.04

could anyone please confirm if this is all or if I'm  missing another setting that has to be done to make it work? 
Is there a miss-entry in the settings mentioned above?

Best Regards, Michael

I'm running the same version with the same configuration, of mixed mode windows/dnn authentication.  I have turned on and off the impersonation, and I am using the latested AD provider for DNN 5.0.  I have about 30 users out of 300 (so far) who are having issues with the auto login not working.  I added a link to the windowssignin page as a temporary solution, but for some users, that link doesn't work, and they have to click it several times before it authenticates them at all.  The users are running XP and Win 2000, and IE 6 and IE 7.  It doesn't appear to be a browser issue.  I'm also having issues from different branches from Key West to Naples, so I don't think it's a domain controller issue.  I've tried setting up the AD account in "Authentication Settings" to use even a domain administrator account, but I still have these issues.

I haven't submitted any questions before, so if this should be in a separate thread, please tell me, but this seemed very similar to my issue, and was the most recent thread on this topic.
