I am setting up security on a new SQL Server. In the Server Role I do not want anyone to have any permissions. However, I find that the default is the public role and that allows for Connect sa permission. Can some please explain this to me. I know that sa is sequel authentication, but how does that effect server role security. In other words when I choose properties on one of the user logins they (by default) get sa connection as a server role. What does this mean?
