can I integrated this solution with login script ?
You can, but it's not very elegant.
Basically AFTER login (most legal documents state something to the affect that you must not allow them to login UNTIL they agree, but Windows does not support that) redirect them to a Web page or other similar documentation. Make them sign something and record it to a .INI file. Then read the ini file for the current user and if name not found then FORCE a log off.
