samba - Feb 2004 - Problems with 'Case-Sensitive' settings.

I am currently running 'Samba 2.2.7a-security-rollup-fix' on a Mandrake
9.1
box.
I have a few pieces of software that are unable to correctly utilize NFS
mounted partitions so I have resorted to using SMB mounted partitions for
this packages.
However, it is critical that the SMB shares follow the same rules that NFS
follows, namely being case-sensitive allowing 'apple' and
'Apple' to exist
in the same folder.
 
I have configured my smb.conf file (both globally, and per share) with the
following parameters:
-- case sensitive = yes
-- preserve case = yes
-- mangle case = no
 
I have restarted the SMB daemon (as well as remounted the partitions)
numerous times.  Each test to create multiple files with mixed-case fails
stating that file X already exists.
 
I can't locate the parameter or missing piece to this puzzle.
 
Can anyone assist with this problem?
 
Thank You,
