samba - May 2005 - Question On PDC, usernames case insensetive on windows

Hi,
Asking  for recommendation.
On the linux, users can be created....
aaa
AAA
aAa
all are different users on linux... similarly with group names
but on Windows this is not valid... 
now in case there is a case that there are two users called Chin and chin... 
will there be a problem with Samba PDC...
if both are added to samba users...

at present the only problem is I see is that users are unable to create there 
profiles on the PDC, users Chin and chin, but is there more to this than 
meets the eye...
regards
Chin Teongli
