I may have made a very bad assumption as I had, indeed, envisioned simple PAM in your multi-user system. Aside from the PAM issue, either of these confront you:
- Does this mean that should you be logged in at the console and you went to another PC you could NOT login?
- You login on one PC, but cannot login from a 2nd?
- IDs other than the root ID cannot login?
