James, once you've determined the filesystem capabilities
for the share, if they're found to be case insensitive and
case preserving, then it needs to override these settings
in the connection struct.

	bool case_sensitive;
	bool case_preserve;
	bool short_case_preserve;

If you do this then the unix_convert() function already
has the logic to bypass case sensitive searches for pathname
lookups that will never be found. This will massively speed
up smbd on directories with thousands of entries when a filename
that doesn't exist is looked up.

Jeremy.
