Now I have no user 501 on my system and no dialout group either. Odd.

With Linux kernel 2.6.x and 2.4.25+, CIFS Unix extensions are in effect, allowing you to view and manipulate Unix-y things like symlinks and suid/sgid files using Samba.


This also has the effect that the Unix UIDs and GIDs from the server get passed to the client.

If you look on the server, you'll see that "501" is the numeric ID for the user that actually owns the file. And though you may not be aware of it, you *should* have a group called "dialout" on the Linux machine. (Look at /etc/group to confirm.) You'll notice that the numeric ID for the "dialout" group on your Linux machine maps to the numeric ID for the file's group on the server.

[In case you were wondering what the point of this is, these changes make Samba play nicer with Unix machines. It makes it possible to replace something like NFS with Samba.]

In the 2.4 series (as of 2.4.25), the Unix extensions are an optional configuration of the Linux kernel (i.e. you enable or disable this when building the kernel). I haven't looked at 2.6 yet, but I suspect it's also optional there. I don't know whether you can turn this behavior off or on after the kernel is built (using a mount option or a /proc setting or something), as I just started using it myself.

FWIW, I've encountered a couple pitfalls myself. I think maybe there are still some issues to work out, so if Samba was previously doing everything you needed it to and you don't need the Unixy features, you might want to use a kernel that has these entensions disabled.

(Just a slight caution: I haven't spent a lot of time using Samba, so I may be a little off with some of the things I just said. If so, hopefully the experts will set the record straight.)
