samba - Jul 2008 - Samba 3.2 PDC - Creating Zone Identifier files and not able to read/write/delete them.

Hello,

I use a Suse 11.0 as a Samba 3.2 PDC. The clients run XP SP3. I have
upgraded a few weeks ago from Suse 10.3 and now all files tranfer that I do
- for example, downloading a file using a web browser - it leaves a trash
file named "transferd-file:Zone.Identifier" or
"tranferd-file:encryptable".

The odd thing is that from Windows I can`t read/write/delete these files.
They appear with names like "hdje2423".

Any help will be apreciated.

Thanks in advance.

Looks like a bug in 3.2.0 that got missed in release.
We now handle named streams in xattrs or in a database
but if we're not using either of those modules we should
refuse to create them (as we did in Samba 3.0.x).

Try this patch, should fix it - will be in 3.2.1.
(attached to this post).

Either that or you can add:

vfs objects = streams_xattr

to the share definition and the named streams will
be correctly stored in xattr's instead (so long as
the filesystem supports them.

It's ok now. Thank you very much.
