Hi all,
in my asp.net 2.0 (VB2005) application I use 
httpContext.Current.User.Identity.Name to get the samaccount of the currently 
logged in user, e.g. DOM\UserA. This works fine for most users, but with just 
1 user we have a case-sensitive problem: It always returns DOM\userA, so a 
small "u" at the start. I've checked his AD-Settings and they seem to be 
correct. I've checked his login (he needs to login to both Windows and then 
Terminal Server) so he really logs in with DOM\UserA (with a capital "U"). 
Nevertheless it does not help, my web app still recoginzes him as DOM\userA.
I've checked 
http://msdn2.microsoft.com/en-us/library/system.web.httpcontext.user(vs.80).aspx 
without success. On IIdentity.Name I got this information "The user name is 
passed to the common language runtime by the operating system or other 
authentication provider (such as ASP.NET)." which also does not really help.

So which field is used to retrieve HttpContext.Current.User.Identity.Name? 
Many thanks in advance!

You can try using "distinguishedName" - See

Hi Kevin,

thanks for the reply, but I don't want to retrieve anything from the Active 
Directory. I just want to know how ASP / IIS 6 retrieves / computes the value 
which is returned when using HttpContext.Current.User.Identity.Name? One user 
logs in with DOM\UserA but it returns DOM\userA. Why is there a small 'u' 
instead of a capital one? For me I could log on as I like, it ALWAYS returns 
DOM\UserB (also when I login to Windows using DOM\userb).
Thanks

It returns the "user name" whatever authentication method you are using so 
the real source could differ.

My guess is that you are using integrated authentication. I'm not sure what 
is the problem. AFAIK the username is not case sensitive i.e. UserA and 
userA are the same user.

I would likely look at where the username is used and needs to be in a 
particular case rather than to try to use a particular case from the start.

Technically I believe it returns the "Windows 2000 legacy name" or something 
similar...

More than likely, it's the AD user object. Check all properties of that 
user (including the object's name itself) for the lowercase "u".
