Yes... You're not loggin in as root, there, so you shouldn't get the sbin paths anyway. Non-root users can often run some sbin things, but normally wouldn't want to anyway.
Switching to root with "su -" should give you the paths back, as well as becoming root, which is, after all, the time when you probably want to run the sbin programs.
In an interactive shell, you'll be running .bash_profile, and in a non-interactive shell, you'll run .bashrc. On RedHat, it makes little difference, but .bashrc will add the ~/bin directory to the path, for user's personal scripts.
They'll also call /etc/bashrc, which sets paths too, but generally by way of the scriptlets in /etc/profile.d/
You'll be glad to know that no paths are getting clobbered, though - the path you've quoted is the right one for a user called "user".
