Changing Kerberos Case on Windows XP

Archived from groups: microsoft.public.windowsxp.security_admin (More info?)

DM - Have you had any feedback on this issue? We are encountering a similar
issue with a third party application that we use. It can use the
userid/password used by Windows, but is case sensitive. So when the Windows
username case changes, user login to that application fails. I don't have a
solution, but I'd appreciate hearing about anything you've discovered on the
issue.
