Some weeks ago we set up DNN with AD integration for our new Intranet. At first, everything seemed to work fine when we tested with some users: First Name, Last Name, Display Name, E-Mail and Roles were correctly synchronzied. Now, after we went live, when I look at our user table, none of our user are synchronized correctly, but get the following information instead:

• Username: DOMAIN\user-id (this, of course, is correct)
• First Name: user-id
• Last Name: (empty)
• Display Name: (empty)
• E-Mail: user-id@our-company.com

I afterwards checked our AD settings in DNN again. While the settings are still the same, I am now getting the following error message when clicking "Update authentication settings":

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 ---

Does someone know what the reason for this behaviour is? Could it be impersonation? But we did not activate impersonation before and everything worked fine. Could it be that we switched from http://123.456.789.10/dotnetnuke to http://our-intranet/? We furthermore did not add our intranet URL to the Intranet Zone of Internet Explorer, but again it was working correctly before without this too.

Regarding Impersonation I furthermore read the AD user guide but anyways do not understand what in general Impersonation is/means and what user account the AD guide is talking about.

Thanks for your help!

I'll be quite interested in hearing from others who use AD Authentication.

I started last week to add AD to a site (I only get to work on it one day a week, so it's "slow going" and my first attempt showed that I needed to upgrade to 4.9.4).  So ... this Friday I may get another shot.

Not that I have an answer to your question, but I'll slowly be getting up to speed.  And, not being that conversant with AD, the documentation gives hints, but isn't encyclopedic.

I know this is an old post but was the question ever answered? I have 5.5.1 installed and have the exact same issue. On version 4.9.1 I installed the AD Login Provider with automatic login. First name, last name, and email would sync up to the AD Attributes correctly. After upgrading to 5.x (I don't remeber exactly which version) the sync stopped.I get the exact same values as mentioned by Jens.

I would recommend asking questions over at the DotNetNuke Authentication forum.  Mike Horton does a great job of answering questions.

Now ... just make sure that your upgrade included the latest version of the provider ...

Joe,

   Thanks for the quick response.... I will follow up with Mike Horton.

please i need your help.

Hi Gonzalo,

I recommend that you ask this question on the forum at DotNetNuke.com for discussion of the Active Directory authentication provider. In the past, I've gotten really good help there with Active Directory questions.
