Industry sources say Sun Microsystems Inc’s claims to have tested its Project Cascade on Windows NT 5 betas is somewhat disingenuous (CI No 3,492). Cascade is a port of AT&T Co’s Advanced Server for Unix – the equivalent of NT 4.x’s network and file and print services running on Unix – to Solaris. To begin with Sun connected the NT 5.0 beta to the NT 4.0 code in ASU. This does not have the same functionality for file and print serving, authentication, and active directory services as the fully-fledged NT 5.0 will incorporate. Moreover because, as the same sources believe, there’s no reason to suppose AT&T’s recent court settlement with Microsoft Corp over rights to NT 5.0 code gave AT&T access to the source (reports say Microsoft paid AT&T off) then AT&T won’t be enhancing ASU for NT 5.0. That said, Sun might be able to negotiate for the important pieces of NT 5.0 such as Active Directory from bona fide licensees such as Cisco Systems Inc but as J. Crew VP systems architecture Marc Hansen told delegates at a Sun conference in New York last week: Cascade is a great idea, but it’s two years too late.
