Hello all:

I wanted to bring this to the attention of the group, as it could cause
some major trouble down the road...

Original Bug (I know anyone on the list should have already gotten this):

	You have been subscribed to a public bug:

	Two computers under Feisty Fawn.
	Filesystem ext3

	1) Open nautilus explorer
	2) Create one file named something.txt
	2) Create another file named Something.txt
	3) Edit something.txt and write "aaaa". Save.
	4) Edit Something.txt and write "bbbb". Save.
	5) Share the folder containing the two files (Windows Sharing - 		SMB).

	On another computer (with nautilus):
	6) Navigate through the network and copy the two files on the 		
Desktop (or elsewhere).
	7) Open the two files with text editor
	result: both files contains "aaaa".

	No errors are signaled during the transfert. This problem can be
	"dangerous" since the copy is not similar from the original 			files.

	** Affects: samba (Ubuntu)
	     Importance: Undecided
	         Status: Confirmed

Additional Comments:

	Justin M. Wray Says -

	Correct me if I am wrong, but this seems more like an issue with 	the
way Windows handles filename case, not SMB/Ubuntu.

	I do not experience the same issue with Sharing Linux -> Linux.

	Not that it takes away the issue, just not an issue on our end.

	Thanks,
	Justin M. Wray

	I agree with you with the fact that Windows doesn't care about 			case.

	The problem is that sharing from Linux to Linux with SMB make 			some
troubles; I didn't try with Windows. A common user may 			encounter
difficulties with this. In fact the two files are 			distinguished while
navigating through the network, but the 			copies are not.

	[...]

	In my case I could experience the problem twice. I'm ready to 			make
further experiments if necessary to help.

	The problem will remain if transferring from Linux to Windows 			since
Windows won't be able to create the two files. However, it 	would be
better if from Linux to Linux the case was handled.

	Justin M. Wray Says -
	Okay, let me also do some further test, on the Linux -> Linux 			side.
As that is something we can deal with.

	Eitherway, we need to come up with an approach for the Linux -> 	
Windows example as well. As this could cause problems 				for news
users, and more likely corporate adoption on the 			server-side. As
such, I'll bring this to the attention of 			ubuntu-server as well.

	Thanks again for the report.

	Thanks,
	Justin M. Wray

Obviously the fear is anyone wanting to use Ubnutu Server to share files
with Windows clients would have trouble with SAMBA when two files with
the same name (and different cases) are involved.

Just wanted to bring it to everyones attention, neodelphi and I will
complete further testing, and will update the bug accordingly.

Thanks.
