[Bug 561281] [NEW] case sensitivity option (case sensitive=no) is not honored

[Sven Ehret]

Public bug reported:

Binary package hint: samba

In my setup using samba's “case sensitive = no” option it is not
possible for Windows machines to create files with the same filename but
different cases. Example: “file.test” can not reside next to
“FILE.test”.

However, when a LINUX client (Gentoo) connects to the SAMBA share, it is
allowed to create such files, ignoring SAMBA's case sensitivity option.
When the same LINUX client connects to a Windows share the behaviour is
correct.
