Case Sensitive Usernames

[Claus Emrich]

Hi,

can somebody tell me who Win2k/XP handles Usernames?
We have developed a Software that uses SSPI to get the
authentication-information. In Windows NT Usernames always were provided by
SSPI in UPPER CASE. So, our Account-Database in the Software lists the
Usernames with UPPER CASE letters. Now, in Win2k/XP the usernames where
provided "as is". If the User types "Miller" the Software get the Username
"Miller" and deny access, because the Softward want "MILLER" to login.
Does anybody knows a way to force Win2k/XP to convert the Usernames in
either UPPER CASE or lower case?

Thanks a lot for your help!

It is best for your software to enforce the case insensitivity=20
by uppercasing what is received before comparing to your=20
internally stored information.
Have you checked in the MSDN library for call options=20
to force LM style names to be returned ? However, as=20
the move is away from the older technologies, and as=20
either resolution involves your modifying your source,=20
you would be best off with internal case insensitivity.
