Re: share permissions

Like Ansgar says use Groups with the appropriate permissions. Always
use Groups and move users in and out. That way you have fewer
permissions to set, check and remove (lower maintenance and simpler to
understand) and each user in a Group will get consistent permissions.

Are then any best practices for setting permissions on shared folders?
We have a discussion on whether we should be setting the access on the
share itself or controlling it more at the NTFS level.  I lean more to
setting permissions on the share and at the NTFS level. Thoughts?

Common practice is to grant full access to everyone on the share level,
and restrict access on the NTFS level. If you are super mega hyper
paranoid, you can restrict share level permissions as well, but IMHO
that has more disadvantages than advantages. For one, troubleshooting
permissions becomes a pain when you have to deal with two sets of ACLs.
Also, share level permissions apply only to the share, while NTFS
permissions apply to the shared folder and all files and subfolders. Not
to mention that NTFS permissions are far more fine-grained than share
level permissions.
