LDAP Connection with ASP .Net

[Guest]

Hello
I'm developping an web application using ASP.Net and I Want that when i write a name i a textbox, the program give me personnals informations stored in LDAP... But i don't know if is it possible and who do that! so i explain what i did.. but it dont works :

First, i create a new C# project with ASP . Net web application.
I add System.DirectoryService reference.
In the WebForm, i put a textbox (id=nom) and a submit button (id=buton).

In the WebForm.aspx.cs, on the clic event i put this function :

********************
private void Button_Click(object sender, System.EventArgs e)
{
SearchResultCollection results = Client.SearchUser(nom.Text);
foreach(SearchResult result in results)
{
Response.Write("Nom de l'utilisateur" + result.Properties["cn"][0]);
Response.Write(result.Properties["title"][0]);
Response.Write(result.Properties["department"][0]);
Response.Write(result.Properties["physicalDeliveryOfficeName"][0]);
Response.Write(result.Properties["telephoneNumber"][0]);
}
}

*****************

And at last, i created a new class, name "client", and i white that :

***************
using System.DirectoryServices ;
using System ;

public class Client
{
static public SearchResultCollection SearchUser(string name)
{
DirectoryEntry root = new DirectoryEntry("ldap://ldap.baylor.edu/ou=Other,ou=People,o=Baylor University,c=US");
DirectorySearcher searcher=new DirectorySearcher(root);
searcher.Filter = "(anr=" + name + ")";
searcher.PropertiesToLoad.Add("cn");
searcher.PropertiesToLoad.Add("title");
searcher.PropertiesToLoad.Add("department");
searcher.PropertiesToLoad.Add("physicalDeliveryOfficeName");
searcher.PropertiesToLoad.Add("telephoneNumber");
return (searcher.FindAll());
}

public static void Main()
{
string[] args = Environment.GetCommandLineArgs();
string name = args[1];
}
}

_______________________________________________

But this code don't run :
on the button clic an error append
*******
On the class Client, at line 16 "return (searcher.FindAll());"
