    I am facing a problem in my web application in the log in Page in ASP.net.The Problem is arising whenever i am authenticating my log in credentials using the LDAP to connect to Active directory in the server.I am giving you the code where the exception is getting thrown. public string[] GetIssuerFromActiveDirectory(string loginName) { try { string[] issuerDetails = new string[3]; string path = ConfigurationManager.AppSettings["LDAPPath"]; string groupName = null; String dn; DirectoryEntry entry = new DirectoryEntry(path); // Bind to the native AdsObject to force authentication.
    Object obj = entry.NativeObject; DirectorySearcher search = new DirectorySearcher(entry); search.Filter = "(SAMAccountName=" + loginName + ")"; SearchResult result = search.FindOne(); issuerDetails[0] = (String)result.Properties["name"][0]; issuerDetails[2] = (String)result.Properties["mail"][0];

                int propertyCount = result.Properties["memberOf"].Count;
                int equalsIndex, commaIndex;
    
                if (propertyCount <= 0)
                    issuerDetails[1] = null;
                else
                {
                    for (int propertyCounter = 0; propertyCounter < propertyCount; propertyCounter++)
                    {
                        dn = (String)result.Properties["memberOf"][propertyCounter];
                        equalsIndex = dn.IndexOf("=", 1);
                        commaIndex = dn.IndexOf(",", 1);
    
                        groupName = (dn.Substring((equalsIndex + 1), (commaIndex - equalsIndex) - 1));
                        if (groupName.Equals(ConfigurationManager.AppSettings["AdminRole"]) || groupName.Equals(ConfigurationManager.AppSettings["MemberRole"]))
                        {
                            issuerDetails[1] = groupName;
                        }
                    }
                }
    
                return issuerDetails;
            }
            catch (CustomException cex)
            {
                throw cex;
            }
            catch (Exception ex)
            {
                Exceptions.LogException(ex);
                CustomException cex = Exceptions.GetCustomException("issuer not present in active directory", ex);
                throw cex;
            }
        }
    

    its giving the exception at
    Object obj = entry.NativeObject; saying refferal was sent to the server. Can anyone help me with this exception.
