Do you have "vfs objects = streams_xattr" or "vfs objects = streams_depot" set on the share ? You'll need this to map named streams to filesystem objects on a POSIX system.

As I already mentioned the :Zone-Identifier stream is working to a certain degree. If I store a file (with Firefox) on the share this stream is created and the explorer property sheet evaluates its content and tells me the file is from the internet (I can "unlock" the file too). It also works if I manually fakes the file's origin. But on the other hand, this stream is not created when I copy a file from another NTFS drive. As there is no use for xattrs in my file system I'd like to get this stuff working without them.

Not correctly, and I don't see how to be honest. > If I store a file (with Firefox) on the share this stream is created and > the explorer property sheet evaluates its content and tells me the file > is from the internet (I can "unlock" the file too). > It also works if I manually fakes the file's origin.

Can't be done. You need to have either the streams_xattr module or streams_depot module enabled to get streams support. Where do you think the stream data will get stored on the filesysytem if you don't enable either of these ?

The way streams are currently handled (just like regular files) is quite sufficient for me. Its just that samba does not advertise this feature. I didn't know about the streams_depot so far. Is there any documentation about the stream naming scheme within the depot directory?
