Yes, you are exactly correct. I goobered that and I am glad you
caught it and put it out there so at least the archives will reflect
the truth.

If the user ID is created with lower-cased letters, it will be stored
and reported in lower-cased letters. At least that is how the Windows
2003 Active Directory where I work expresses its user IDs.
For example, our regular IDs are a number. Some special IDs have
letters added to the beginning of the number.
I am looking at user IDs right now through the AD User and Computers
mmc snap-in and I can see that most of them are in all caps, but some
are not. No matter how I look at the account name for this particular
ID, it is in lower-cased letters.
The reported 'dn' of objects with lower-cased letters have lower-cased
letters in them, so AD will use that to report the values.
I also know that when you initially log on to a system and it creates
a new user profile for you, the folder it creates will have upper /
lower -cased letters based on how you logged on and not on how AD says
your ID should be capitalized.

This is of course the new best answer to the problem and is something
I also routinely do (mostly to distinguish between groups that are in
different domains but would otherwise have the same name).
I have no idea why it wasn't suggested earlier unless we all just
thought he had probably already tried that.
