Connect to Active directory through Biztalk

Hi ,

I want to retrieve active directory user information . I have writen a standalone application & it’s worked fine for me. here is the part of the code

DirectoryEntry de = new DirectoryEntry(_path, username, password);

DirectorySearcher mySearcher = new DirectorySearcher();

“(&((&(objectCategory=Person)(objectClass=User)))(samaccountname=” + staffInfo.EmployeeID  ))”;

“name”);

result = mySearcher.FindOne();

But when I call this through Biztalk using .net componet in orchestration I am getting the following error.

Inner exception: The specified domain either does not exist or could not be contacted.

Exception type: COMException

Source: System.DirectoryServices

Target Site: Void Bind(Boolean)

The following is a stack trace that identifies the location where the exception occured

at System.DirectoryServices.DirectoryEntry.Bind(Boolean throwIfFail)

at System.DirectoryServices.DirectoryEntry.Bind()

at System.DirectoryServices.DirectoryEntry.get_AdsObject()

at System.DirectoryServices.PropertyValueCollection.PopulateList()

at System.DirectoryServices.PropertyValueCollection..ctor(DirectoryEntry entry, String propertyName)

at System.DirectoryServices.PropertyCollection.get_Item(String propertyName)

at System.DirectoryServices.DirectorySearcher.get_SearchRoot()

at System.DirectoryServices.DirectorySearcher.FindAll(Boolean findMoreThanOne)

at System.DirectoryServices.DirectorySearcher.FindOne()

Can any one help me why this is happening. Do I need to do add this active directory user to Biztalk group?

Thank you,

Best regards,

Nandika
