Centralized Authentication between Solaris and NT

We run a Windows Network. Our main business application runs on Sun Solarix (UNIX). Currently both systems need separate logons.

We need a script / configuration that would enable us to achieve a single logon. ## Deliverables 1) Complete and fully-functional working script(s) or program(s) as well as complete source code of all work done. 2) Exclusive and complete copyrights to all work purchased.
