How to Authenticate Lotus LDAP Directory in asp.net web Application

dear all,

have requirement authenticate web application using ldap authentication against lotus notes(not active directory).

besides list of user ldap. i able list of users ldap using following class

ldapconnection

searchrequest 

searchresponse 

searchresultentrycollection 

don't know how authenticate user ldap password. able validate user id.

whether password can taken?

how find encryption have used.

kindly guide me on same.

many suggest following code, not validating users' password rather user alone. password given in code used binding ldap directory. 

public bool isauthenticated(string domain, string username, string pwd)
    {
      string domainandusername = domain + @"\" + username;
      directoryentry entry = new directoryentry(_path, domainandusername, pwd);

      try
      {
        //bind native adsobject force authentication.
        object obj = entry.nativeobject;

        directorysearcher search = new directorysearcher(entry);

        search.filter = "(samaccountname=" + username + ")";
        search.propertiestoload.add("cn");
        searchresult result = search.findone();

        if(null == result)
        {
          return false;
        }

        //update new path user in directory.
        _path = result.path;
        _filterattribute = (string)result.properties["cn"][0];
      }
      catch (exception ex)
      {
        throw new exception("error authenticating user. " + ex.message);
      }

      return true;
    }
