I recently install Active Directory 05.00.04 to my current DNN 6.2.4 for my intranet. I have setup my module settings as per detail below :

Enabled - Yes
Hide Login Controls - No
Synchronize Role - No
Do Not Automatically Create Users - No
Provider - ADSI Authentication Provider
Authentication Type - Delegation
Root Domain:  dc=ism,dc=net,dc=my
User Name: ism.arief
Password: XXXXXXXXXX
Confirm Password: XXXXXXXXXX
Email Domain: @ism.net.my
Default Domain
Auto-login IP Address (Optional):
Allowed Search Bots

I have edited my webconfig un-commenting the line below and add my username & password:

<identity impersonate=”true” userName=”ism.arief” password=”XXXXXXX” />

I have edited as well the file DesktopModules/AuthenticationServices/ActiveDirectory/WindowsSignin.aspx in IIS giving directory security access to only Windows Authentication only.

 However, i keep getting error below :

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.Settings.UpdateSettings() --- End of inner exception stack trace ---

However, the weird thing is if i browse my browser to /DesktopModules/AuthenticationServices/ActiveDirectory/WindowsSignin.aspx , it seems to working fine !! I was able to logon using my active directory !! But the module part is keep getting the error.

I am trying to fix the module, but to no avail. I hope any members here can help me on this
