[Samba] Question about Case Insensitivity

Hi,
I am trying to make a Linux filesystem appear case-insensitive and I got the
idea that I could use a SAMBA loopback mount to do this. I almost succeeded on
my first try but I ran into a snag I have no answer for yet.
My setup involves sharing filesystem "/a" and then mounting it on "/b". I can
use "ls -l" on the "/b" filesystem in a case-insensitive fashion but when I go
to open the file by a case-insensitive name the attempt fails.
Can someone please explain why I am not able to open() files with case
insensitive names even though stat() or lstat() works with them?
These examples illustrate my issue:
Case sensitive ext3 filesystem:
# ls -l /a/AbCd/EFgh
-rw-r--r-- 1 root root 6 Oct 24 10:18 /a/AbCd/EFgh
# ls -l /a/abcd/efgh
ls: /a/abcd/efgh: No such file or directory
Case insensitive mount.cifs mount of SAMBA shared "/a" filesystems:
# ls -l /b/AbCd/EFgh
-rw-r--r-- 1 root root 6 Oct 24 10:18 /b/AbCd/EFgh
# ls -l /b/abcd/efgh
-rw-r--r-- 1 root root 6 Oct 24 10:18 /b/abcd/efgh
But why doesn't open(2) work in a case insenstive fashion?
# cat /b/AbCd/EFgh
hello
# cat /b/abcd/efgh
cat: /b/abcd/efgh: No such file or directory
