Hello, I'm having trouble connecting to an LDAP server within ASP .Net 2.0 using C#.  I can connect to the server via the Softerra LDAP Browser but when I try to add the credentials and run through asp it blows up.  
 
These are my settings in Softerra:
Host: 111.222.333.444
Port: 389
Base: ou=people,o=xxx

Credentials:
User DN: cn=fn.ln,ou=people,o=xxx
Password: password

LDAP Settings -> Connection Options:
Filter: (objectClass=*)

-----

Here is my code in ASP:

                DirectoryEntry de = new DirectoryEntry();
                de.Path = "LDAP://111.222.333.444:389/ou=people,o=xxx";
                de.Username = "cn=fn.ln,ou=people,o=xxx";
                de.Password = "password";

                DirectorySearcher srch = new DirectorySearcher(de);
                srch.Filter = "(cn=some.one)";

                using (SearchResultCollection results = srch.FindAll())
                {
                    foreach (SearchResult res in results)
                    {
                        Console.WriteLine("\t{0}", res.Path);
                    }
                }

The error occurs with this line:
     using (SearchResultCollection results = srch.FindAll())


Thanks,
Tim
