samba - Jul 2004 - UID for CIFS mounts

Hi,
Appologies if this is obvious, but the documentation isn't clear to
me, and my google skills don't seem to be up tp scratch today.

Basically:
If I mount a CIFS share as on a linux box, and then multiple users on
that machine use that share, who do they use it as? The user that
mounted or themselves (users are authenticated via pam + winbind on
the linux box)

Is it possible to have them all authenticated as them selves?

We want to have users logging in via SSH and then accessing files on a
Windows 2000 server. It's not clear to me how this would be
accomplished from the docs, as a user name is supplied when mounting
the share, how could the Windows 2000 server then trust the linux box
that the user accessing it is really a different user and not the one
who mounted it?

Does the user that mounts the share have to be a powerful user to
achieve this? Or could a guest or anonymous user mount the share since
the user permissions should be coming from those users that are
actually accessing the files.

Thanks for any help
Chris

Ok, I've tested this, and can't seem getthis happening. But can
someone please confirm this:

If I have a Windows 2000 share with several users files, and the ACL's
permitting only the owner to access their files, is it possible to
mount this Windows 2000 share on a linux box, and ensure that such
ACL's are applied to the users? (presumably using Winbind or something
similar to get User's from Active Directory)


(I have done googling and manual reading and the answer is unclear, so
I would really appreciate it if someone could give me a difinitive
answer)
