- TITLE :RAS Password Authentication Failed
- PRODUCT :Windows NT
- PROD/VER:3.10
- OPER/SYS:WINDOWS
- KEYWORDS:BUGLIST3.10 FIXLIST3.10.001
-
- --------------------------------------------------------------------
- The information in this article applies to:
-
- - Microsoft Windows NT Advanced Server version 3.1
- - Microsoft Windows operating system version 3.1
- --------------------------------------------------------------------
-
-
- SYMPTOMS
- ========
-
- Windows NT Remote Access Clients cannot be validated if the password
- contains extended characters. Extended characters have ASCII codes
- above 128.
-
- CAUSE
- =====
-
- The situation surrounding this problem is very complex and it involves
- several interrelated Windows NT bugs besides #996.
-
- Basically, if your Windows NT RAS client password contains any
- Extended characters, RAS client authentication will not properly
- convert their case (that is, uppercase versus lowercase). This will
- cause Windows NT RAS authentication to fail. It works fine for
- characters "a-z" and "A-Z."
-
- RESOLUTION
- ==========
-
- Until a bug fix is released, do not use extended characters in your
- Windows NT passwords. This is especially true for Remote Access and
- Services for Macintosh.
-
- STATUS
- ======
-
- Microsoft has confirmed this to be a problem in Windows NT and Windows NT
- Advanced Server version 3.1. This problem was corrected in the latest U.S.
