Re: Folder permissions

Hi,

I'm getting some confusing test results on shared folder permissions.

I've a standard "Domain Users" group, of which everyone is a member.
I've a "GGVPs" group of which only certain people are a member
I've a testuser USER, who is a memeber of Users.

I've a share: \\serv1\Public which has R/W to all Domain Users

I need to limit \\serv1\Public\AM_test\folder to Read/write of GGVPs,
but not readable by anyone else.

If I apply a Deny to Domain Users, then no-one in GGVPs can access the
folder.

So I Create the folder as:

Administrators (Full Control - This folder, sub and files))
Creator/Owner (Full control - Subfolders and files only)
SYSTEM (Full Control - This fold, sub and files)

Then if I add "testuser" to GGVPs and add Read access for GGVPs to the
folder, then that user can get in ok.

Heres where it goes strange. If I remove testuser from the GGVPs
group, that user can STILL get in. If I remove GGVPs, then that user
can't get in... and if I then add the group again, then testuser can
still access it, even though its not a member of GGVPs anymore.

Any chance theres some caching going on?


No, it's because you're using Domain Users - and creator/owner is weird &
hard to understand. To keep things simple & make this work more easily for
you, I suggest a couple of things -

a) Don't use Domain Users (or creator/owner) for your any permissions
settings on folders you create/share. Create your own groups to use, remove
Domain Users. I create an AD security group called "Companyname Staff" and
use that, as my general group. Plus others (Management, Accounting, HR,
whatnot).

b) Don't get into the business of applying different security for different
subfolders within a single shared folder.....it will lead to madness. Create
additional shares at the same level, instead. If you have a folder called
PUBLIC, and you have subfolders containing data that not everyone who sees
PUBLIC should be able to access, don't put them there - create additional
shares. I tend to set up folders called Shared (\\server\shared%$),
Management (\\server\management$), Accounting (\\server\accounting$) and so
forth - with the appropriate groups granted permission to each.

You should try posting in m.p.windows.server.general for more help ....this
isn't SBS specific, and you may as well cast a wider net.
