Hello, I installed version 1.00.03 on DNN version 4.08.02 and it passed the install process with no problems:
Accessing Global Catalog:
OK
Checking Root Domain:
OK
Accessing LDAP:
OK
Find all domains in network:
2 Domain(s):

However, when I select Windows Signin and enter my AD credentials, it says Login Failed.

If I browse to WindowsSignin.aspx, I get the following error: Object reference not set to an instance of an object.
Stack Trace:

[NullReferenceException: Object reference not set to an instance of an object.]
DotNetNuke.Authentication.ActiveDirectory.ADSI.ADSIProvider.GetUser(String LoggedOnUserName) +144
DotNetNuke.Authentication.ActiveDirectory.UserController.GetUser(String LoggedOnUserName) +45
DotNetNuke.Authentication.ActiveDirectory.AuthenticationController.SynchronizeRoles(String LoggedOnUserName, Int32 intUserID) +60
DotNetNuke.Authentication.ActiveDirectory.AuthenticationController.AuthenticationLogon() +499
DotNetNuke.Authentication.ActiveDirectory.WindowsSignin.Page_Init(Object sender, EventArgs e) +187
System.Web.UI.Control.OnInit(EventArgs e) +2117356
System.Web.UI.Page.OnInit(EventArgs e) +9
System.Web.UI.Control.InitRecursive(Control namingContainer) +321
System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +692

In my web.config, I have identity impersonation turned on with my username and password. I have also set the minRequiredPasswordLength field to the minimum length used for our passwords. I followed the install PDF and have reinstalled several times with no luck.

Any help would be great. Thanks.

What OS is the server running and what OS are your AD controllers running?

The server is running Windows Server 2003, and I believe the AD controllers are running Server 2003 as well.

I'll have to look into what the possible problems are then as that's the same setup that I'm running.

The only thing I can think of is I removed the LiveID and OpenID providers before installing the AD prodiver because I do not need them.
Would that have removed any functionallity that is needed for AD authentication?
