DOCUMENT:Q127103 08-AUG-2001 [winnt] TITLE :Mac Clients Must Log On to Trusted Domains - No Pass-through PRODUCT :Microsoft Windows NT PROD/VER:3.1 3.5 3.51 4.0 OPER/SYS: KEYWORDS:kbnetwork ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Advanced Server, version 3.1 - Microsoft Windows NT Server versions 3.5, 3.51, 4.0 ------------------------------------------------------------------------------- SYMPTOMS ======== From a Macintosh client, if you log into a Windows NT master domain and then access a resource in a Windows NT domain that trusts the master domain, you must re-enter your user ID and password. This occurs even when Services for Macintosh is configured to use the Microsoft User Authentication Module. CAUSE ===== Windows NT clients are able to take advantage of Windows NT pass-through validation, where when you have an account on the master domain, you can access any trusting domain's resources without having to re-enter your name and password. However, the design of the Macintosh redirector and the AppleTalk protocol does not allow for participation in pass-through validation. Thus, you must re-enter your user ID and password. STATUS ====== This is a limitation of the Macintosh network client The Macintosh computer and AppleTalk protocol are manufactured by Apple Computers, Inc., a vendor independent of Microsoft; we make no warranty, implied or otherwise, regarding this product's performance or reliability.
