Hi just curious, What is the computing/networking model for a site with many users, say, as PF? Is it to grant access to each user to a shared drive? Sorry if this is too simple. I mean, I understand that first I login and I have to be first authenticated, then authorized to access certain network resources. How is that all stored and organized. Is it a domain controller where I am part of a collection of users and/or groups with specified permissions? EDIT: In a database system such as SQL Server I understand I first get access to the general network with a login, either through Windows or through SQL Server. In order to use a database, I must be made into a user of said database. But tha t just gives me access to the database, without the ability to do anything. I must then be assigned a role, which brings with it a set of permissions. How does this work when granting access to different users to a general site/network? Thanks.
