[Samba] Permissions problem

[Doug Curtis]

I am having problems settings permissions on files or directories.  I am
running Samba 3.0.4 with domain logins.

Let's say that I have a share where everyone in the domain has access to it
but there are a couple of files in that share that only two of the people in
the domain need access to them.  With my old NT domain, I could right-click
on the files and change the security settings.  Whenever I try to modify the
files security settings, I get an Access is denied message.  I am logging
into the domain with admin privledges.

So does this mean I have to either:

a) create a new share just for these two people?
or
b) create a group for these two people and chgrp the files to this newly
created group?
or
c) change some settings on my server because I should be able to modify a
files security settings?

Thanks,

Doug
