First of all I don't need or want Auto Login.

Like others, I've run into problems getting the initial setup quite right.

When I try the Root Domain format as (DC=domain,DC-local I get the following 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.Settings.UpdateSettings() --- End of inner exception stack trace ---

I have seen this error posted a dozen times, but nobody ever clearly says what it means or what causes it.  Mike, or anyone, please clarify this error if you can please.

If I try the Root Domain format as (LDAP://domain.local) I get the following error:

Accessing Global Catalog:
FAIL
Checking Root Domain:
OK
Accessing LDAP:
FAIL
Find all domains in network:
Could not access LDAP to obtain domains info
The specified domain either does not exist or could not be contacted.
The specified domain either does not exist or could not be contacted.

So, I get an OK on the Checking Root Domain, but accessing the Global Catalog and Accessing LDAP fails.

The server is running as a stand alone server (WORKGROUP) but when I run the ldp.exe diagnostic program I seem to be able to connect and bind to LDAP using the credentials I was  given.

Is it possible that I don't have all of the ports open between the server and the Domain Controller?
