We have had a corporate website hosted on a computer within the local network. AD authentication has been working just fine with these parameters:

Root Domain:   dc=INTRANET
Default Domain: INTRANET

We moved the website to a hosted site outside of the internal corporate network.  AD Authentication is now failing with the same settings.  If I go to the site and just update settings, I get this:

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 ---

---------------
So, I changed the settings (having looked at the documentation) to:

Root Domain:   dc=INTRANET.mycompany, dc=com
Default Domain: INTRANET

Now I don't get an exception, but I do get another error:

Accessing Global Catalog:
FAIL
Checking Root Domain:
FAIL
Accessing LDAP:
FAIL
Find all domains in network:
Could not access LDAP to obtain domains info
Logon failure: unknown user name or bad password.


Where should I go from here?

I am still struggling with this and have not been able to resolve the problem.

To recap, we moved our corporate website to an external host, but we still want our internal users to be able to login to the site using their AD credentials.

The site is mycompany.com.  This is external and outside of our firewall.  It is running DNN 5.5.1 and AD Provider 5.0.2.

Our AD domain is intranet.mycompany.com.

I have specified the Root Domain as "dc=intranet.audaciousinquiry,dc=com"

This results in the following string of errors when I try to update AD settings:

Accessing Global Catalog:
FAIL
Checking Root Domain:
FAIL
Accessing LDAP:
FAIL
Find all domains in network:
Could not access LDAP to obtain domains info
Logon failure: unknown user name or bad password.

---------
To make sure that I could configure AD inside of my firewall, I installed a local version of DotNetNuke (5.6.0) and configured AD with Root Domain set to "dc=intranet,dc=local" and all of the other parameters the same as I configured the web site.  With these settings, I am able to authenticate with AD on the local installation.

---------
In all honesty, I'd flying a little blind here.  I understand that the external website says that it cannot find the LDAP server.  We have opened up the firewall so that all requests from the IP of the website are passed through.

I'd appreciate any ideas on how I might try to debug this.

Thanks!

Yes, the website is part of the mycompany.com website. Thanks, though, for the suggestion to use LDAP Browser. I'll see if the hosting company can support that.
