DirectoryServices error!

[Enosh Chang]

Hi all,

I encounter some problem in DirectoryServices, could someone help me?

private void InitLoginUser()
{
DirectoryEntry objEntry = new DirectoryEntry();
DirectorySearcher objSearcher = new DirectorySearcher();
SearchResult objResult;

try
{
objEntry.Path = "LDAP://dc=iec,dc=inventec";

objSearcher.SearchRoot = objEntry;
objSearcher.Filter = "(sAMAccountName=*464*)";
objSearcher.SearchScope = SearchScope.Subtree;
objSearcher.PropertiesToLoad.Add("displayName");
objResult = objSearcher.FindOne();
} // try
finally
{
} // finally
}

private void Page_Load(object sender, System.EventArgs e)
{
// ±N¨Ï¥ÎªÌµ{¦¡½X¸m©ó¦¹¥Hªì©l¤Æºô*¶
if (!IsPostBack)
InitLoginUser();
}

But it always show error message as following:

Hi,

you need to write the full domain name with DCs

For example if the domin name is microsoft.com it should be :

DC=microsoft,DC=com

Connect to computers in a domain. For example, "LDAP://CN=
computer-name, CN=Computers, DC= domain-controller1, DC=
domain-controller2,...".
