I am suffering from making Windows Authentication for a week, hope you could kindly help me.  Thanks a lot!

All I want to develop is:

Use dotnetnuke in a company environment, that is to say , in intranet. All NT Authorized Users or at least domain users can automatically login in the site.

I am using method 4.9.1, and methods I have tried are:

download ActiveDirectory_01.00.04, and follow it user guide to configure, but in Active Directory Settings page, I got the error:

Error: is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: Object reference not set to an instance of an object. ---> System.NullReferenceException: Object reference not set to an instance of an object. at DotNetNuke.Authentication.ActiveDirectory.ADSI.Utilities.AddADSIPath(String Path, Path ADSIPath) at DotNetNuke.Authentication.ActiveDirectory.ADSI.Utilities.GetRootEntry(Path ADSIPath) at DotNetNuke.Authentication.ActiveDirectory.ADSI.ADSIProvider.GetNetworkStatus() at DotNetNuke.Authentication.ActiveDirectory.AuthenticationController.NetworkStatus() at DotNetNuke.Authentication.ActiveDirectory.Settings.UpdateSettings() --- End of inner exception stack trace ---

Please help me on this. Thank you very much.

Hi Zhang,

I am getting the same error as you had.
Can you post the solution in here?

The problem I have is that my DNN server is on the DMZ domain and my Active Directory is located in a different network and building.
